a compact multi-band metamaterial-inspired antennaincorporating shorting pins

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 overalldimensions 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.

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 magnetodielectric behavior at the lower frequencies. With the aid of effective material, a miniaturized printed patch antenna operating at 650 MHz is achieved. In some frequency bands, the MTM structure efficiently provides an artificial magnetic conductor (AMC). This latter feature helps to achieve efficient multiband 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).
