EXPANDABLE WIRELESS TRANSCEIVER
First Claim
1. An expandable wireless transceiver, comprising:
- an antenna, for detecting an electromagnetic signal from surrounding space and receiving a signal with a first central frequency according to the detection result;
a receiver, coupled to the antenna for receiving the signal delivered by the antenna;
a transmitter, for outputting a radio-frequency signal with a second central frequency; and
a switch connector, having a first connection terminal coupled to the transmitter, a second connection terminal coupled to the antenna and a third connection terminal, wherein the third connection terminal provides an connective path to an expansion antenna, and the first connected terminal delivers the radio-frequency signal with the second central frequency to the second connection terminal or the third connection terminal according to the coupling condition of the third connection terminal,wherein the expandable wireless transceiver transmits the radio-frequency signal with the second central frequency to surrounding space through the antenna or the expansion antenna, and the second central frequency and the first central frequency are both in a specific band.

Abstract
An expandable wireless transceiver is provided. The expandable wireless transceiver includes an antenna, a receiver, a transmitter and a switch connector. The antenna detects an electromagnetic signal in surrounding space and receives a signal with a first central frequency according to the detection result. The receiver receives the signal based on the detection result of the antenna. The transmitter outputs a radio-frequency signal. A third connection terminal of the switch connector provides a connective path to an expansion antenna. According to the coupling condition of the third connection terminal, the switch connector delivers the radio-frequency signal to its second connection terminal or third connection terminal. Thus, the radio-frequency signal with a second central frequency is transmitted to surrounding space through the antenna or the expansion antenna, wherein the second central frequency and the first central frequency are both in a specific band.
