ABSTRACT:
This portable microwave radiation monitor utilizes an antenna formed in a dual Archimedean spiral. The power density of the electric field is indicated on a meter coupled to diode means connected across the inner terminals of the antenna by inductance means selected to resonate with the variable capacitance of the diode, substantially at the frequency of the field being monitored.
