Referring toFIG.1, a detachable antenna100includes a light-emitting module110, a connector120, and an antenna module130. The light-emitting module110includes a bias circuit111and a light-emitting unit112(a light signal unit). The bias circuit111includes an input end, a first output end, and a second output end. The input end of the bias circuit111is coupled to the connector120. The first output end of the bias circuit111is coupled to the antenna module130. The second output end of the bias circuit111is coupled to the light-emitting unit112. The input end of the bias circuit111receives a mixed signal S1from the connector120. The mixed signal S1includes a communication signal S2and a drive signal S3. It is worth noting that, the bias circuit111of this embodiment is, in an embodiment, a bias Tee circuit. The connector120of this embodiment is a sub miniature version A (SMA) connector. The light-emitting module110of this embodiment is a light-emitting diode (LED) light board. The light-emitting unit112of this embodiment includes one or more LEDs. The antenna module130of this embodiment includes a copper tube antenna.

In this embodiment, the detachable antenna100is adapted to be mounted on a device body of an electronic device to provide communication and light emitting functions. The detachable antenna100is electrically connected to a circuit board in the device body of the electronic device through the connector120to receive the mixed signal S1from a single pin of the connector120. In this embodiment, the bias circuit111outputs the communication signal S2and the drive signal S3in the mixed signal S1to the antenna module130and the light-emitting unit112respectively, so that the antenna module130transmits a wireless signal according to the communication signal S2, and the light-emitting unit112is illuminated according to the drive signal S3. Therefore, the detachable antenna100of this embodiment uses the single pin to receive the mixed signal S1, and performs the communication and light emitting functions simultaneously.

In this embodiment, the communication signal S2is an analog signal, and the drive signal S3is a digital signal. In an embodiment, the communication signal S2is a radio frequency (RF) signal with 2.4 GHz or 5 GHz, and the drive signal S3is a direct current voltage signal (less than 60 mA) with 3.3 V.

Referring toFIG.2, a detachable antenna200includes a light-emitting module210, a connector220, and an antenna module230. The light-emitting module210includes a bias circuit211and a light-emitting unit212. The bias circuit211includes an input end N1, an output end N2, and an output end N3, and includes a circuit node CN1, an inductor2111, and a capacitor2112. An inductance of the inductor2111is, in an embodiment, 27 nH. A capacitance of the capacitor2112is, in an embodiment, 10 pF. In this embodiment, the circuit node CN1is coupled to the input end N1, the output end N2, and the output end N3. One end and the other end of the inductor2111are respectively coupled between the circuit node CN1and the output end N3. One end and the other end of the capacitor2112are respectively coupled between the output end N3and a ground end (a ground voltage). In this way, when the detachable antenna200is mounted on an electronic device, the connector220receives a mixed signal S1provided by the electronic device. The mixed signal S1includes a communication signal S2and a drive signal S3. The mixed signal S1is inputted to the bias circuit211via the input end N1, and flows through the circuit node CN1. The mixed signal S1is outputted to the antenna module230via the output end N2, so that the antenna module230implements a communication function according to the communication signal S2in the mixed signal S1.

It is worth noting that, because the communication signal S2is an analog signal, and the drive signal S3is a digital signal, the drive signal S3in the mixed signal S1does not affect an antenna function of the antenna module230. However, in an embodiment, the bias circuit211also includes another capacitor coupled between the circuit node CN1and the output end N2to block the drive signal S3from being transmitted to the antenna module230via the output end N2. In an embodiment, one end of the another capacitor is coupled to the circuit node CN1, and the other end of the another capacitor is coupled to the output end N2.

In this embodiment, the communication signal S2being the analog signal in the mixed signal S1is blocked by the inductor2111, so that only the drive signal S3being the digital signal in the mixed signal S1passes through the inductor2111, and the capacitor2112filters out signal noise of the drive signal S3. Therefore, the output end N3of the bias circuit211outputs the drive signal S3to the light-emitting unit212. In this embodiment, the light-emitting unit212includes a plurality of LEDs2121_1to2121_N and a plurality of resistors2122_1to2122_N, where N is a positive integer. One end and the other end of the resistors2122_1to2122_N are respectively coupled between the output end N3and respective first ends of the LEDs2121_1to2121_N. Second ends of the LEDs2121_1to2121_N are respectively coupled to the ground end. Resistances of the resistors2122_1to2122_N are, in an embodiment, 330 OHM respectively.

In this embodiment, the drive signal S3drives the LEDs2121_1to2121_N to implement a light emitting function. The light emitting function of the LEDs2121_1to2121_N is used for, in an embodiment, providing a light signal indicating related indication information such as a light signal indicating a current communication state. In addition, for other technical features of the detachable antenna200of this embodiment, refer to the description of the detachable antenna100of the embodiment ofFIG.1, and so on.
