Design of a Single Negative Metamaterial based Microstrip Patch Antenna
From the observation of radiation pattern of microstrip antenna integrated with MeTaMaterial (MTM) cover has an improved gain compared to the gain of the microstrip antenna without MTM cover. An improvement of the gain from 10.48db to 11.94db in simulation was obtained when MTM cover is placed in front of the microstrip antenna. However, despite increasing of gain, a bigger side and back lobe was also been introduced. If the side and back lobe can be reduce, the gain of the microstrip antenna with MTM cover can be further improved.
