摘要：
An innovative wideband omnidirectional horizontally polarized (HP) antenna is presented for 4G Long Term Evolution (LTE) wireless communication and networking systems. The proposed planar antenna consists of four pairs of flag-shaped radiators, a balun for balance-unbalance transformation, and four parasitical strips for bandwidth enhancement. Such a design enables in-phase and axially symmetric current flowing along the radiators. The measurements show that the proposed HP antenna exhibits a relative bandwidth of 41% with the return loss greater than or equal to 10 dB; it covers the frequency band of 1.76-2.68 GHz, including PCS, UMTS/LTE, Bluetooth, ISM, and WLAN bands. With an omnidirectional radiation pattern in E-plane, the proposed antenna has a peak gain of 3.6-4.2 dBi across the operational band and a radiation efficiency of 83%. The low profile and compact design, along with the omnidirectional radiation pattern, makes it ideal for ceiling or surface-mounted indoor and automobile 4G applications.
