摘要：This paper presents a shorted planar quasi semicircular monopole antenna (SPQSMA) for wideband wireless communication application. The shorting strip reduces the size of the antenna. A modified CPW feed is designed to match with 50Ω input impedance. Simulations have been performed to investigate the different characteristics of the antenna. This antenna has desirable characteristics such as very wide dual band (865 MHz to 1.42 GHz and 2.17 GHz to 20 GHz), low cost, ease of manufacture, compact size, bidirectional radiation pattern. The magnetic field distribution of the antenna is shown and a slot of semicircular shaped is introduced at the centre of radiator to reduce the weight, volume and cost of the antenna. The proposed antenna is suitable specially for GSM band and ultrawideband (UWB) applications.
