Dual Band Gap Coupled Patch Antenna for Wireless Communications

“…In last decade, the many developments in a microstrip patch have gone through in terms of design and applications such as dual-band antenna-inpackage with T-shaped slots [21], annular-ring microstrip antenna for GNSS applications [22], compact dual-band GPS antenna design [23], wideband dual-beam U-slot microstrip antenna [24], dualband WLAN/UWB printed wide slot antenna for MIMO/diversity applications [25], low prole antenna for body centric communications [26], compact notch loaded half disk patch antenna for dual band operation [27], proximity fed gap coupled compact semi-circular disk patch antenna [28], F-shape microstrip line fed dual band antenna [29] [31], toppled H-shaped microstrip patch antenna [32], proper use of meta materials have enhanced the bandwidth and gain of microstrip antenna without compromising its physical dimensions [33], triple-band single-fed compact microstrip antenna [34], multi-frequency monopole antennas that is loaded with complementary meta-material transmission line (CMTL) [35], multi-frequency complementary split ring resonators (CSRRs) [36]. All these research paper published have their own limitations such as complicated geometry, low gain, poor radiation eciency, lack of theoretical analysis and the experimental verication of theoretical results.…”
