Abstract
A wideband horizontally polarized (HP) omnidirectional antenna is presented. The tightly coupled array (TCA) mechanism is ultilized into the design of the antenna to realize reduced lower cut-off frequency and improved bandwidth. The −10dB impedance bandwidth is 102.6% from 4.8GHz to 14.7GHz. Meanwhile, uniform omnidirectional radiation patterns with a gain variation of less than 3dB are obtained within the frequency band of 4.7–8GHz (51.96%).
