Title: A compact pentagonal monopole antenna for portable UWB systems
Author: Thomas, Paulbert; Gopikrishna, M; Aanandan, C K; Mohanan, P; Vasudevan, K
Abstract: Design of a compact microstrip-fed ultra-wideband antenna suitable for USB dongle and other such space constraint applications is presented. The structure consists of a pentagonal monopole element and a modified ground plane that gives an impedance bandwidth from 2.8 to 12 GHz. Radiation patterns are stable and omni-directional throughout the band with an average gain of 2.84 dBi. The antenna occupies only 11 × 30 mm2 on FR4 substrate with permittivity 4.4.
