Zusammenfassung: | The invention is applicable to the fields of wireless electric signal transmission, and provides an antenna used in electronic equipment. The electronic equipment comprises a printed circuit board and a ground layer; the printed circuit board is provided with a test terminal; the ground layer is positioned on the printed circuit board; the antenna comprises antenna bodies and a switch modulator-demodulator; the antenna bodies are arranged on the ground layer at intervals; the switch modulator-demodulator is electrically connected between the printed circuit board and the antenna bodies; the switch modulator-demodulator comprises a first input end, a second input end and an output end; the antenna bodies are provided with low-frequency signal access points and high-frequency signal access points; wires, extend out of the low-frequency signal access points, for electrically connecting the antenna bodies with the first input end; wires, extend out of the high-frequency signal access points, for electrically connecting the antenna bodies with the second input end; and the test terminal is electrically connected with the output end. When the first input end is electrically connected with the output end by the switch modulator-demodulator, a low-frequency signal antenna is formed, and when the second input end is electrically connected with the output end by the switch modulator-demodulator, a high-frequency signal antenna is formed |
