An elliptical SRR low-profile multiband antenna-backed AMC for wireless applications and satellite communications

Abstract This paper presents a low-profile, triple-band elliptical coplanar waveguide-fed antenna designed using the split-ring resonator technique. An artificial magnetic conductor with three zero-phases of the reflection coefficient is incorporated as a reflector to improve the antenna gain. The results show a gain enhancement of 3.4, 5.65, and 1.5 dBi at the three frequency bands of interest centered on 2.45, 5.2, and 8 GHz, respectively. The first two operational bands are Industrial, Scientific and Medical bands (2.33–2.59 and 4.97–5.48 GHz) that can be particularly used for wireless local area network and Bluetooth applications, while the third band (7.48-8.59 GHz) is suitable for military and satellite communications. The proposed solution that is designed, fabricated, and tested exhibits a good agreement between measured and simulated results.
