Abstract :
We introduced a new concept of a coplanar patch antenna (CPA) and presented simulation and experimental results for the antenna. The coplanar patch antenna consists of a patch surrounded by closely spaced ground conductor and a CPW feed line, which has a similar geometric configuration as the loop slot antenna. Simulation and experiment results clearly demonstrated that the CPA behaves, particularly the resonant property, more similar to the microstrip patch antenna rather than a loop slot antenna. Simulated and measured results for the return loss, radiation pattern and gain were presented. A good agreement between the simulation and measurement has been obtained. The similarity of the microstrip patch antenna and coplanar patch antenna, and some design consideration for the patch have been described.
