Abstract

In this paper, a low-cost compact microstrip line-fed antenna with parasitic patches resulting 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 of 4.4. It has a partial ground plane. This antenna is exited by a microstrip-line feed. The return loss is less than -10 dB in 3.7 GHz-11.6 GHz frequency range with Possible UWB application. The proposed antenna is also simulated with band notch in 5 GHz-6 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.
