Abstract :
The conventional microstrip patch antenna has low gain and low directivity. This paper presents coaxial feed rectangular microstrip patch antenna with left-handed material (LHM) and photonic bandgap (PBG) circular holes. The left-handed material has a new unit cell structure which is a double split rectangular ring resonator. It has effective negative parameters in the frequency of 6.9GHZ. By using both techniques of left-handed material and PBG circular holes, the performance of the antenna have been improved obviously. The simulation results and measurement data verified the proposed patch antenna.
