Directivity and Bandwidth Enhancement of Proximity-Coupled Microstrip Antenna Using Metamaterial Cover
Keywords:
Metamaterial cover, FDTDAbstract
Two major problems associated with patch antennas are low gain and narrow bandwidth. This paper is mainly concerned with directivity and bandwidth enhancement of proximity-coupled microstrip antenna using metamaterial cover. Compared to the patch without metamaterial cover, bandwidth of the antenna is improved about 2.33% and directivity is increased about 9.91dB. The commercial software CST Microwave Studio and a full-wave FDTD numerical technique, developed by the authors, are adopted for the simulations.
