1. An antenna system for wireless transmission, comprising:
an antenna; and a logarithmic detector amplifier (LDA) connected to the antenna configured to cancel radio interference in transmission data received or transmitted by the antenna, the LDA comprising:
an amplifying circuit having an input port, and configured to receive, at the input port, an input signal having a first frequency and to generate an oscillation based on the input signal;one or more resonant circuits coupled to the amplifying circuit and configured to establish a frequency of operation of the system and to generate, at a first output port, a first output signal having a second frequency, the second frequency being substantially the same as the first frequency; anda controller circuit connected to the amplifier input and configured to cyclically terminate oscillation of the input signal each time a pre-determined threshold of voltage is detected, the controller circuit including a low pass filter configured to generate, at a second output port, a second output signal having a repetition frequency at a third frequency, wherein the antenna is coupled to the input port of the amplifying circuit and is configured to transmit a first transmit signal, and wherein the first transmit signal is amplified by the LDA operating in a reverse mode.
