本發明涉及一種天線罩，特別是指一種具限縮雷達偵測範圍功能的天線罩及雷達偵測裝置。 The present invention relates to an antenna cover, and more particularly to an antenna cover and a radar detection device having the function of limiting the radar detection range.
一般雷達偵測裝置都是事先根據預定規格設計其發射天線的增益，使雷達偵測範圍符合預定的需求。若是要縮小雷達偵測範圍，就需要適應性地改變電路板的運作條件來降低發射天線的增益。然而，這種方式會降低雷達偵測裝置的偵測精確度。 Typically, radar detection devices are designed with their transmitting antenna gain pre-designed according to predetermined specifications, ensuring that the radar detection range meets predetermined requirements.

請參考圖1至圖5所示，本發明根據一實施例提供的一天線罩1是適於被安裝在一雷達偵測裝置中。雷達偵測裝置包含一電路板20，電路板20包含一天線晶片21，天線晶片21包含至少一接收天線22和至少一發射天線23。以下將以天線晶片21只有一個接收天線22和一個發射天 線23作為範例來說明。 Referring to Figures 1 to 5 , an antenna housing 1 according to one embodiment of the present invention is suitable for installation in a radar detection device. The radar detection device includes a circuit board 20, which includes an antenna chip 21. Antenna chip 21 includes at least one receiving antenna 22 and at least one transmitting antenna 23. The following description uses an example in which antenna chip 21 includes only one receiving antenna 22 and one transmitting antenna 23.
天線罩1包含一罩體10，罩體10為金屬材質且包含一頂遮部11和一支撐部12。支撐部12具有一第一端和相對於第一端的一第二端。支撐部12的第一端接觸且固定於電路板20，支撐部12的第二端則連接頂遮部11的周緣，使得頂遮部11與天線晶片21在電路板20的法線N上相隔一預定距離D，也使得頂遮部11遠離電路板20。此預定距離D例如但不限於是介於1.2mm至1.8mm之間，例如大約1.2mm、1.4mm、1.6mm或1.8mm，較佳為大約1.6mm。 The antenna cover 1 includes a housing 10 made of metal and comprising a top cover 11 and a support 12. The support 12 has a first end and a second end opposite the first end. The first end of the support 12 contacts and is fixed to the circuit board 20, while the second end of the support 12 connects to the periphery of the top cover 11. This ensures that a predetermined distance D separates the top cover 11 from the antenna chip 21 along the normal N of the circuit board 20, thereby positioning the top cover 11 away from the circuit board 20. This predetermined distance D is, for example, but not limited to, between 1.2 mm and 1.8 mm, such as approximately 1.2 mm, 1.4 mm, 1.6 mm, or 1.8 mm, and preferably approximately 1.6 mm.
在本實施例中，支撐部12的第一端設有多個固定腳14，且這些固定腳14可分別插入並被固定於電路板20的多個固定孔24；然而，本發明並不限於此實施例。在其他的實施例，固定腳14的數量和固定孔24的數量可改成一個，且固定腳14的位置和固定孔24的位置可視實際情況調整；或者，支撐部12的第一端改設有至少一個固定孔24，而電路板20則改設有至少一個固定腳14；或者，天線罩1與電路板20之間的固定方式可改成黏合或其他方式。 In this embodiment, the first end of the support portion 12 is provided with multiple fixing legs 14, which can be inserted into and fixed to multiple fixing holes 24 on the circuit board 20. However, the present invention is not limited to this embodiment. In other embodiments, the number of fixing legs 14 and the number of fixing holes 24 can be reduced to one, and the positions of the fixing legs 14 and the fixing holes 24 can be adjusted according to actual circumstances. Alternatively, the first end of the support portion 12 can be provided with at least one fixing hole 24, while the circuit board 20 can be provided with at least one fixing leg 14. Alternatively, the antenna cover 1 and the circuit board 20 can be fixed together using adhesive bonding or other methods.
頂遮部11設有至少一鏤空孔13。此至少一鏤空孔13露出天線晶片21的至少一接收天線22和至少一發射天線23。頂遮部11的鏤空孔13的數量對應(例如大於或等於)接收天線22的數量和發射天線23的數量的總和。 The top cover 11 is provided with at least one cutout hole 13. This at least one cutout hole 13 exposes at least one receiving antenna 22 and at least one transmitting antenna 23 of the antenna chip 21. The number of cutout holes 13 in the top cover 11 corresponds to (e.g., is greater than or equal to) the total number of receiving antennas 22 and transmitting antennas 23.
舉例來說，在本實施例中，頂遮部11的鏤空孔13的數量只有一個，天線晶片21也只有一個接收天線22和一個發射天線23，此鏤空孔13完全露出接收天線22和發射天線23，甚至更完全露出天線晶片21。 但在其他實施例中，當接收天線22的數量和發射天線23的數量的總和是2或大於2時，頂遮部11的鏤空孔13的數量可改成是二個(如圖8至圖11所示)或二個以上，且這些鏤空孔13完全露出與其相對應的那些接收天線22和發射天線23。 For example, in this embodiment, the top cover 11 has only one cutout hole 13, and the antenna chip 21 has only one receiving antenna 22 and one transmitting antenna 23. This cutout hole 13 fully exposes both the receiving antenna 22 and the transmitting antenna 23, or even more fully exposes the antenna chip 21. However, in other embodiments, when the total number of receiving antennas 22 and transmitting antennas 23 is two or greater, the top cover 11 may have two or more cutout holes 13 (as shown in Figures 8 to 11), and these cutout holes 13 fully expose their corresponding receiving antennas 22 and transmitting antennas 23.
在本發明中，鏤空孔13的形狀例如但不限於是矩形(如圖1至圖4、圖8和圖9所示)、圓形(如圖10和圖11所示)或其他形狀。 In the present invention, the shape of the hollow hole 13 is, for example but not limited to, a rectangle (as shown in Figures 1 to 4, 8, and 9), a circle (as shown in Figures 10 and 11), or other shapes.
請參考圖6A至圖6D來示範性說明圖3的當雷達偵測裝置未安裝天線罩1時和之後的輻射場型的變化。圖6A中，線TE1代表當雷達偵測裝置未安裝天線罩1時發射天線23在水平方向的輻射場型，線TH1代表當雷達偵測裝置未安裝天線罩1時發射天線23在垂直方向的輻射場型。圖6B中，線RE1代表當雷達偵測裝置未安裝天線罩1時接收天線22在水平方向的輻射場型，線RH1代表當雷達偵測裝置未安裝天線罩1時接收天線22在垂直方向的輻射場型。圖6C中，線TE2代表當雷達偵測裝置已安裝天線罩1時發射天線23在水平方向的輻射場型，線TH2代表當雷達偵測裝置已安裝天線罩1時發射天線23在垂直方向的輻射場型。圖6D中，線RE2代表當雷達偵測裝置已安裝天線罩1時接收天線22在水平方向的輻射場型，線RH2代表當雷達偵測裝置已安裝天線罩1時接收天線22在垂直方向的輻射場型。 Please refer to Figures 6A to 6D for exemplary illustration of the changes in the radiation pattern of the radar detector device before and after the antenna dome 1 is installed in Figure 3. In Figure 6A, line TE1 represents the horizontal radiation pattern of the transmitting antenna 23 when the antenna dome 1 is not installed, and line TH1 represents the vertical radiation pattern of the transmitting antenna 23 when the antenna dome 1 is not installed. In Figure 6B, line RE1 represents the horizontal radiation pattern of the receiving antenna 22 when the antenna dome 1 is not installed, and line RH1 represents the vertical radiation pattern of the receiving antenna 22 when the antenna dome 1 is not installed. In Figure 6C, line TE2 represents the horizontal radiation pattern of transmitting antenna 23 when the radar detector device is installed with antenna dome 1, and line TH2 represents the vertical radiation pattern of transmitting antenna 23 when the radar detector device is installed with antenna dome 1. In Figure 6D, line RE2 represents the horizontal radiation pattern of receiving antenna 22 when the radar detector device is installed with antenna dome 1, and line RH2 represents the vertical radiation pattern of receiving antenna 22 when the radar detector device is installed with antenna dome 1.
從圖6A和6B可知，在加裝天線罩1之前，天線的輻射場型較為對稱。從圖6A和6C可知，在加裝天線罩1之後，由於天線輻射受到天線罩1的頂遮部11的左右兩側的金屬阻礙，使得圖4中靠右側(圖面右側)的發射天線23的輻射場型往左傾。同樣地，從圖6B和6D可知，在加裝 天線罩1之後，圖4中靠左側(圖面左側)的接收天線22的輻射場型往右傾。並且，從圖6C和6D可知，發射天線23的輻射能量較集中在水平方向，接收天線22的輻射能量也較集中在水平方向。藉此，可使得雷達偵測裝置整體的雷達偵測範圍縮小。 As shown in Figures 6A and 6B, before the antenna cover 1 is installed, the antenna's radiation pattern is relatively symmetrical. However, as shown in Figures 6A and 6C, after the antenna cover 1 is installed, the antenna's radiation is obstructed by the metal on the left and right sides of the top shield 11 of the antenna cover 1, causing the radiation pattern of the transmitting antenna 23 (on the right side of the drawing) in Figure 4 to tilt to the left. Similarly, as shown in Figures 6B and 6D, after the antenna cover 1 is installed, the radiation pattern of the receiving antenna 22 (on the left side of the drawing) in Figure 4 tilts to the right. Furthermore, as shown in Figures 6C and 6D, the radiation energy of the transmitting antenna 23 is more concentrated in the horizontal direction, and the radiation energy of the receiving antenna 22 is also more concentrated in the horizontal direction. This can reduce the overall radar detection range of the radar detection device.
請參考圖7來示範性說明在圖3的雷達偵測裝置的電路板20的運作條件不變的情況下，天線晶片21的發射天線23和接收天線22的增益在安裝天線罩1之前和之後的變化，其中天線晶片21運作在大約頻率60.5GHz~61GHz之間。圖7中，曲線CT1代表當雷達偵測裝置未安裝天線罩1時發射天線23的增益隨不同頻率變化，曲線CT2代表當雷達偵測裝置已安裝天線罩1時發射天線23的增益隨不同頻率變化，曲線CR1代表當雷達偵測裝置未安裝天線罩1時接收天線22的增益隨不同頻率變化，曲線CR2代表當雷達偵測裝置已安裝天線罩1時接收天線22的增益隨不同頻率變化。 FIG7 illustrates, for example, how the gain of the transmitting antenna 23 and receiving antenna 22 of the antenna chip 21 changes before and after installing the antenna cover 1, while maintaining the operating conditions of the circuit board 20 of the radar detection device shown in FIG3 . Antenna chip 21 operates at a frequency between approximately 60.5 GHz and 61 GHz. In Figure 7, curve CT1 represents the gain of transmitting antenna 23 as it varies with frequency when the radar detector device is not equipped with antenna cover 1. Curve CT2 represents the gain of transmitting antenna 23 as it varies with frequency when the radar detector device is equipped with antenna cover 1. Curve CR1 represents the gain of receiving antenna 22 as it varies with frequency when the radar detector device is not equipped with antenna cover 1. Curve CR2 represents the gain of receiving antenna 22 as it varies with frequency when the radar detector device is equipped with antenna cover 1.
從曲線CT1和CR1的比較和曲線CT2和CR2的比較可知，相較於發射天線23發射的雷達波，接收天線22接收的回波都有能量損耗的情形。從曲線CR1和CR2的比較可知，曲線CT2的輻射增益較曲線CR1的輻射增益差，表示有天線罩1的雷達偵測裝置的發射天線23有一定比例的能量沒有被雷達偵測裝置輻射出去(也就是說，被天線罩1屏蔽掉)，因此有安裝天線罩1的雷達偵測裝置的雷達偵測範圍較未安裝天線罩1的雷達偵測裝置的雷達偵測範圍(例如距離約25cm)小。 Comparing curves CT1 and CR1, and curves CT2 and CR2, reveals that the echo received by receiving antenna 22 suffers from energy loss compared to the radar wave emitted by transmitting antenna 23. Comparing curves CR1 and CR2 reveals that the radiation gain of curve CT2 is lower than that of curve CR1, indicating that a certain percentage of the energy from transmitting antenna 23 of the radar detector device with antenna dome 1 is not radiated by the radar detector device (in other words, it is shielded by antenna dome 1). Consequently, the radar detection range of the radar detector device with antenna dome 1 is smaller than the radar detection range (e.g., approximately 25 cm) of the radar detector device without antenna dome 1.
因此，本發明的雷達偵測裝置可以方便地被運用在僅需要小範圍的雷達偵測上，例如設在道路旁的行人優先按鈕，如此雷達偵測 裝置便可只偵測試圖觸碰行人優先按鈕的手指的手勢，而排除只是單純靠近行人優先按鈕但沒有試圖要用手指觸碰的行人，以及排除其他離行人優先按鈕較遠的的行人。 Therefore, the radar detection device of the present invention can be conveniently used in applications requiring only a small range of radar detection, such as a pedestrian priority button located along the road. In this way, the radar detection device can only detect gestures of fingers attempting to touch the pedestrian priority button, while excluding pedestrians who simply approach the button but do not attempt to touch it, as well as pedestrians who are farther away from the button.
雖然本發明以前述之實施例揭露如上，然而這些實施例並非用以限定本發明。在不脫離本發明之精神和範圍內，所為之更動、潤飾與各實施態樣的組合，均屬本發明之專利保護範圍。關於本發明所界定之保護範圍請參考所附之申請專利範圍。 Although the present invention is disclosed above with reference to the aforementioned embodiments, these embodiments are not intended to limit the present invention.
