Abstract
A novel wideband horizontally polarized omnidirectional antenna (HPOA) with an electrical conductor reflector is proposed for the 4th generation (4G) Long Term Evolution (LTE) applications. The proposed antenna consists of four pairs of printed dipoles distributed on the front and back of the substrate, and a star-shape patch integrated with stepped parallel strip lines constitutes a balun for the unbalance-balance transition from the coax feeding to the antenna. Both simulated and measured reflection coefficients (S11) demonstrate a wide -10 dB impedance bandwidth of 39.6%, from 1.82 to 2.72 GHz. This band covers PCS, UMTS, LTE 2300, LTE 2500, WLAN and Bluetooth bands. The presented antenna has a peak gain of 3.2 and 4.0 dBi at 1.95 and 2.48 GHz, respectively, and an omnidirectional radiation pattern in E-plane. HPOA may be suitable for ceiling-mounted indoor 4G applications.
