Experimental Investigation of Planar Frequency Dispersive Phase Shifter for Base Station Antennas

A frequency-dispersive phase shifter that can be integrated in dual band: 1.5 GHz and 2.0 GHz mobile base station antennas has been proposed to improve communication capacity by increasing the tilt angle of the multiband mobile base station antennas’ low-frequency band. This paper presents the prototype results of the phase shifter by obtaining the simulated and measured S-parameter and transmission phase characteristics.
