Design of compact ACS feed microstrip antennafor UWB application

In this article, a compact Asymmetric Coplanar Strip (ACS) Feed Microstrip antenna has been summarized and reported. Designed antenna has very compact size of 12m × 24 mm and has been simulated over the CADFEKO EM Simulation tool. Proposed ACS antenna has been simulated against the Ultra-Wide Band (UWB) operating region with frequency of 3.10 GHz to 10.60 GHz. Simulated antenna shows <;-10 dB reflection coefficient bandwidth all over the UWB region and poses 90% of operating efficiency. Proposed antenna has been modeled with semicircular patch and slotting methods have been adopted for proper UWB operation. Antenna has been simulated with FR-4 dielectric substrate with effective dielectric constant of 4.4 and loss tangent of 0.02.
