Abstract:
This letter presents a compact double-flip trapezium monopole antenna (D-FTMA) for ultra wideband (UWB) application. A significant impedance bandwidth improvement of 7:1 can be achieved at a centre frequency of 7.96 GHz compared to the conventional antenna when the dual bevel technique is deployed near the ground plane. The proposed compact antenna consists of 22 mm  25.8 mm radiating element and 64 mm  40 mm rectangular ground plane and fed by a 50 X coaxial connector. Furthermore, the low cost D-FTMA is fabricated on the FR4- PCB. The antenna agrees between simulation and measurement of return loss, which covers the UWB frequency range (3.1–10.6 GHz). The D-FTMA has a very constant and high relative gain at particular frequency up to 6 dBi. Moreover, the D-FTMA is observably capable in producing divisive radiation patterns with linear polarization at four different frequencies: 4, 6, 8, and 10 GHz. The parameter optimization analysis has been studied using CST Microwave Studio. The presented simulated results are supported by the measurement as well. VC 2012 Wiley Periodicals, Inc.
