Wideband coplanar waveguide fed coplanar patch antenna

In this paper, we have presented simulation and experimental results of wideband coplanar waveguide fed coplanar patch antennas. The antennas were developed to widen the narrow bandwidth of the newly suggested coplanar patch antennas. This was achieved by introducing two identical parasitic patches next to the resonant edges of the main patch. Simulation was done by a commercial package. Antennas operated at 10GHz were designed and fabricated. Return loss, radiation patterns and gain of the antennas were measured. An impedance bandwidth (return loss < -10 dB) of about 8.0 % and stable radiation patterns were observed, gain of the antennas were about 9.0 dBi. Design procedures and experience of the antennas have been discussed.
