The contact lens element 140 includes a second wireless transceiver 150, wherein the second wireless transceiver 150 can be used to receive the wireless signal SW from the reflector 130.

In some embodiments, the first wireless transceiver 120 and the second wireless transceiver 150 may both cover an operating frequency band, wherein the operating frequency band is greater than or equal to 60 GHz. Therefore, the first wireless transceiver 120 and the second wireless transceiver 150 may at least support broadband operation of millimeter wave (mmWave) or terahertz (THz) communication.

Under the design of the present invention, the reflector 130 is helpful to enhance the radiation gain of the first wireless transceiver 120. Generally speaking, after using the reflector 130, the radiation beam of the first wireless transceiver 120 will be more concentrated in the same direction, thereby improving the communication quality between the first wireless transceiver 120 and the second wireless transceiver 150.

The following embodiments will introduce various different configurations and detailed structural features of the communication device 100. It must be understood that these drawings and descriptions are only examples and are not intended to limit the present invention.

The remaining features of the communication device 200 in FIG. 2 are similar to those of the communication device 100 in FIG. 1 , so both embodiments can achieve similar operating effects.

FIG. 3 is a schematic diagram showing a communication device 300 according to an embodiment of the present invention. FIG. 3 is similar to FIG. 1. In the embodiment of FIG. 3, a first wireless transceiver 320 of the communication device 300 includes one or more antenna elements 321, 322, and the communication device 300 further includes an eyeball-tracking module 360, wherein the eyeball-tracking module 360 is disposed on the frame element 110.

The first wireless transceiver 320 can further receive an external signal SX. For example, the external signal SX can come from a smart phone or a wireless access point, but is not limited thereto. In some embodiments, the first wireless transceiver 320 can generate a wireless signal SW according to the external signal SX. In other embodiments, the first wireless transceiver 320 can also directly relay the external signal SX. That is, the wireless signal SW transmitted to the reflector 130 can be equivalent to the external signal SX mentioned above.

In addition, after executing an eye detection procedure, the eye tracking module 360 can generate a control signal SC based on an eye detection signal SE. For example, the eye detection signal SE may be related to the rotation state of an eye. Then, the first wireless transceiver 320 can select one of the radiation beam directions 326, 327, 328, 329 based on the control signal SC. That is, the first wireless transceiver 320 can transmit the wireless signal SW along the selected radiation beam direction. In response to the selected radiation beam direction, a reflector 330 of the communication device 300 will correspond to one of the plurality of reflection directions 431, 432, 433, 434. That is, the reflector 330 can reflect the wireless signal SW along the corresponding reflection direction. Under this design, the communication device 300 will have the function of beamforming or beam switching to achieve the required adjustable reflection mechanism. The remaining features of the communication device 300 of FIG. 3 are similar to those of the communication device 100 of FIG. 1, so both embodiments can achieve similar operating effects.
