Double H shaped metamaterial embedded compact RMPA

This paper presents a compact double H shaped metamaterial-embedded rectangular microstrip patch antenna. The slots are cut in rectangular microstrip patch antenna (RMPA) to decrease the resonant frequency, but this leads to impedance mismatch. To overcome this effect a double h shaped metamaterial is embedded inside the slot. This technique not only provides a good impedance matching and bandwidth, but in addition, also provides the 34% compactness in size. The proposed antenna is simulated and optimized using HFSS software. The prototype antenna has been fabricated and measured results of the proposed antenna are in good agreement with simulated results.
