Claim 5:
6. An antenna, comprising:
an antenna module, configured to receive an electromagnetic wave signal and convert it into an alternating current signal;
a first rectifying circuit, configured to output a corresponding first direct current signal according to the alternating current signal generated by the antenna module;
a second rectifying circuit, configured to output a second direct current signal according to the alternating current signal generated by the antenna module; and
a differential amplifying circuit, configured to receive the first direct current signal and the second direct current signal, amplify a difference between the first direct current signal and the second direct current signal and output an amplified difference between the first direction current signal and the second direct current signal,
wherein the first direct current signal and the second direct current signal have directions opposite to each other, the first rectifying circuit comprises at least one of a first band-pass filter and a first low-pass filter,
the antenna module comprises two receiving antennas, and the two receiving antennas are connected with the first rectifying circuit and the second rectifying circuit in one-to-one correspondence.
