Abstract :
This paper describes the design of a new broad-band, dual-frequency coplanar waveguide fed slot-antenna. This antenna operates at about 27 GHz and 40 GHz. It has a return loss that is about 20 dB at each of the two operating frequencies, with a maximum gain of about 4.5 dBi. The cross-polarization is about 30 dB less than the co-polarization. Matching the antenna at the two widely separated frequencies is achieved using a special matching network of resonant slot antennas.
