Abstract :
In this paper, a low-cost compact microstrip line-fed antenna with parasitic patches resulting a Wide-band characteristics with a band dispensation is presented. The antenna was implemented on FR4 substrate with a thickness of 1.6 mm and relative permittivity(εr) of 4.4. It has a partial ground plane. This antenna is exited by a microstrip-line feed. The reflection coefficient (S11) is less than -10 dB in 3.7 GHz-11.1 GHz frequency range with possible ultra-wideband (UWB) application. The proposed antenna is also simulated with band notch in 4.9 GHz-5.9 GHz frequency range by introducing an inverted U shape slot. The return loss results and radiation pattern plots of the antenna are included in this paper. The performance characteristics of the proposed antenna are simulated using CST microwave studio 2008 software.
