Abstract :
In this paper a technique for improvement of radiation efficiency of metamaterial zero order antenna based on increasing of vertical antenna height is presented. Comparison of the two microstrip line implementation of the zero order resonator (ZOR) antennas with different height over ground plane is demonstrated. Improved ZOR antenna exhibit 75% efficiency compared to 10% of the reference antenna.
