Title :
Wideband dual-polarized base station antenna for GSM1800 and WCDMA UMTS
Abstract :
The goal is to design an antenna that covers the WCDMA UMTS and GSM1800 bands: 1710...2170 MHz. Two polarizations are required. The antenna element is aimed to be used in base stations, as an element for a phased array. The implementation uses a large-volume square patch antenna in order to reach a wide bandwidth. The maximum bandwidth for the volume is achieved with the secondary auxiliary resonator. The dielectric feed arrangement helps reach good cross-polar characteristics. This work is done using the FDTD simulations. The antenna was designed with a single feed, and the dual feed case is compared to it. The antenna achieves the goals reasonably well
