Abstract :
Dual dipole antennas have been developed in the frequency range of 33-50 GHz and 105-135 GHz for use as imaging array elements in an electron cyclotron emission imaging (ECEI) and microwave imaging reflectometry (MIR) plasma diagnostic system respectively. A wideband balun with less than 3 dB back to back insertion loss was achieved in the frequency range of 1.7 GHz-19.8 GHz (1:11.7) for convert IF signals from the balanced antenna to the unbalanced transmission line/connector.
