New Mechanism for Feeding Integrated Elevated Patch Antennas

A new concept for feeding an elevated patch antenna is presented for first time. The antenna scheme maximizes the antenna radiation performance on high dielectric substrates. The elevated antenna patch is excited by feeding a metal post directly connected with the radiator, and it also vertically mounted at the end of the centre conductor of the covered coplanar waveguide (C-CPW) line underneath the patch. Our results show that the bandwidth is 4.3 GHz, determined from 10 dB return loss and the gain is about 6.3 dB at G-band frequencies (140GHz-220GHz) with nearly constant broadside radiation pattern over its bandwidth.
