In addition, the term "or" used in this document may include any one or more combinations of the associated listed items as the case may be.

[First embodiment]

Referring to Figures 1 to 4, the first embodiment of the present invention provides an antenna module M with a light-emitting function, which includes: a radio frequency and DC signal shunt circuit structure 1, an antenna structure 2, and a light-emitting structure 3.

First, as shown in FIG1 , the RF and DC signal shunt circuit structure 1 includes a circuit substrate 10, a shunt capacitor 11 disposed on the circuit substrate 10, and a shunt inductor 12 disposed on the circuit substrate 10. In addition, the antenna structure 2 is electrically connected to the shunt capacitor 11 of the RF and DC signal shunt circuit structure 1, and the light-emitting structure 3 is electrically connected to the shunt inductor 12 of the RF and DC signal shunt circuit structure 1. Thus, when an RF signal RF and a DC signal DC transmitted from the outside of the RF and DC signal shunt circuit structure 1 are input into the RF and DC signal shunt circuit structure 1 through the "same signal transmission line L", the RF signal RF can be transmitted to the antenna structure 2 through the shunt capacitor element 11 (at this time, the RF signal RF will not pass through the shunt inductor element 12), and the DC signal DC can be transmitted to the light-emitting structure 3 through the shunt inductor element 12 (at this time, the DC signal DC will not pass through the shunt capacitor element 11).

Furthermore, as shown in FIG1 , the RF and DC signal shunt circuit structure 1 includes a first electrical connector 13, a second electrical connector 14, and a third electrical connector 15, the antenna structure 2 and the circuit substrate 10 are separated from each other, and the light-emitting structure 3 and the circuit substrate 10 are separated from each other. Further, the first electrical connector 13 is disposed on the circuit substrate 10 and electrically connected to the signal transmission line L to receive the RF signal RF and the DC signal DC. The second electrical connector 14 is disposed on the circuit substrate 10 and electrically connected to the antenna structure 2 to output the RF signal RF to the antenna structure 2, so that the RF signal RF can be transmitted and received through the antenna structure 2. The third electrical connector 15 is disposed on the circuit substrate 10 and electrically connected to the light-emitting structure 3 for outputting a DC signal DC to the light-emitting structure 3, so that the light-emitting structure 3 can generate a light source through the power (DC power supply) provided by the DC signal DC.

In addition, as shown in FIG. 1 , the circuit substrate 10 has a first conductive path 101, a second conductive path 102, and a third conductive path 103. More specifically, the first conductive path 101 is electrically connected between the first electrical connector 13, the shunt capacitor 11, and the shunt inductor 12, so as to transmit the radio frequency signal RF and the direct current signal DC to the shunt capacitor 11 and the shunt inductor 12, respectively. The second conductive path 102 is electrically connected between the shunt capacitor 11 and the second electrical connector 14, so as to transmit the radio frequency signal RF from the shunt capacitor 11 to the second electrical connector 14. The third conductive path 103 is electrically connected between the shunt inductor element 12 and the third electrical connector 15 to transmit the DC signal DC from the shunt inductor element 12 to the third electrical connector 15.

For example, the shunt capacitor 11 may be a ceramic capacitor or any passive element that can be used to filter a DC signal (or, such a passive element may not be used), and the shunt inductor 12 may be a ceramic inductor or any passive element that can be used to filter a RF signal (or, such a passive element may not be used). Since the shunt capacitor 11 and the shunt inductor 12 may be ceramic capacitors and ceramic inductors, respectively, the present invention can be used to withstand high power transmission, and this feature is suitable for small base stations. In addition, the antenna structure 2 can be an antenna structure applied to Wi-Fi 6E or Frequency Range 1 (including the full frequency band below 6 GHz, such as between 410 MHz and 7125 MHz) for 5G, or any antenna structure that can be used to transmit and receive radio frequency signals RF, and each frequency band has the characteristics of "low insertion loss" and "high isolation (that is, the characteristics of being able to share a line without mutual interference, and being able to simultaneously transmit and receive radio frequency signals RF and generate luminous effects)". In addition, the light-emitting structure 3 can include at least one light-emitting diode chip, or any at least one light-emitting element that can be used to generate a light source. However, the above example is only one of the feasible embodiments and is not intended to limit the present invention.

For example, as shown in FIGS. 2 to 4, the RF and DC signal shunt circuit structure 1 includes a plurality of matching inductance elements 11A and a plurality of matching capacitance elements 12A. Further, one of the plurality of matching inductance elements 11A and the plurality of matching capacitance elements 12A can be disposed on the second conductive path 102 of the circuit substrate, and electrically connected in parallel or in series between the shunt capacitance element 11 and the second electrical connector 14, so that the present invention can provide better antenna impedance matching (for example, as shown in FIG. 2 or FIG. 4, one matching inductance element 11A can be used). Furthermore, another one of the multiple matching inductance elements 11A and the multiple matching capacitance elements 12A is arranged on the third conductive path 103 of the circuit substrate, and is electrically connected between the shunt inductance element 12 and the third electrical connector 15 in parallel or series, so that the present invention can provide better antenna impedance matching (for example, as shown in Figure 3 or Figure 4, one matching capacitance element 12A can be used). That is, the present invention can provide better antenna impedance matching by selecting the matching inductor 11A and/or the matching capacitor 12A (that is, in the second conductive path 102 and the third conductive path 103, it is not limited to use the matching inductor 11A or the matching capacitor 12A, and the number of the matching inductor 11A and the matching capacitor 12A used is not limited), and by adjusting the parallel or series electrical connection mode.
