The capability of complementary capacitively-loaded-loop (CCLL) inspired metamaterial (MTM) to
miniaturize printed patch antenna is examined. The cell etched at the antenna ground plane. The
antenna is comprised of three main sections: CCLL cell, shorting pins, and a patch with the overall
dimensions of 50×25 mm2. It is shown that the MTM structure exhibits a magneto-dielectric
behavior at the lower frequencies. With the aid of the effective material, a miniaturized printed patch
antenna operates at 650 MHz has been achieved. In some frequency bands, the MTM structure
efficiently provides an artificial magnetic conductor (AMC). This later feature helps to achieve
efficient multi-band operation and the antenna can cover the required frequency band of the most
commercial wireless communication systems, such as LTE 2500/2600 (2480 to 2730 MHz),
radiolocation service (2890 to 3110 MHz) and LTE 3500/3700, WLAN 3600 (3640 to 3880 MHz).
In order to validate the simulation results, a prototype of the antenna is fabricated and tested. Good
agreement between the simulation and measurement results is obtained.
