Abstract

A novel wideband horizontally polarized omnidirectional (HPO) antenna with coupling lines is proposed for indoor wireless base station applications. It consists of four microstrip dipoles, a tune disk with four square-shaped perturbations and four pairs of tapered parallel transmission lines. Each right arm of the microstrip dipole has been engraved with a coupling line. The measured 10 dB return loss (RL) relative bandwidth is 51% (1.6-2.72 GHz). In horizontally plane, the proposed antenna has an omnidirectional radiation pattern and anaverage gain of 2.4 dBi.
