Abstract

In this paper, a novel compact single whip wideband antenna with an improved omnidirectional wideband antenna is proposed. Firstly, a single whip antenna is designed on a thin flexible printed circuit (FPC) with a tapered coplanar waveguide feed line. This proposed antenna shows a wide impedance matching performance in a frequency ranged from 194-2124 MHz with a bandwidth ratio of 10:1, while a measured return loss is better than 10 dB within the desired passband. The single whip antenna has demonstrated an ultra-wide bandwidth with satisfactory radiation properties in lower frequency band. However, the omnidirectional radiation pattern deteriorated in higher frequency band. Three whipped antennas are co-designed to form an improved omnidirectional radiation pattern. Finally, the measured performance of the fabricated antenna shows a good agreement with that obtained through simulation results.
