Miniaturized Metamaterial Antenna for 5.7 GHz Services

This paper provides multiband antenna-based Metamaterial for gains improvement. Here, the developed antenna constitutes patches such that the first is square-shaped and printed on a Taconic FR-30 substrate. In addition, for exciting the first patch, the process used conduction, whereas the other was capacitively coupled to the source as the impedance of either should be matched accordingly. Furthermore, the second patch constitutes a metasurface layer designed and placed on it as a superstrate, which increases the antenna gain towards the CRLH. The results show a maximum gain of 14.5 dBi at 5.7 GHz with maximum dimensions of 200× 200mm2. Moreover, this antenna operates at additional frequency bands (1.1 GHz, 1.3 GHz, 1.7 GHz, 3 GHz, 3.1GHz, 3.4 GHz, 4.7 GHz, 4.9 GHz, 5.7 GHz and 5.9 GHz), with a minimum reflection coefficient of −18.2db, −11.75db, 11.52db, −20.3db −17.47dB, −14.27dB, −11.3dB, −13.9dB −10.16dB and, −14.69dB respectively. The proposed antenna is designed and analyzed using the CST MWS simulator.
