Dual Polarized Dual Fed Vivaldi Antenna for Cellular Base Station Operating at 1.7–2.7 GHz

Figure 1

The simulation model of one radiator. (a) Dual polarized radiator structure with the coordinate system (b) and radiator structure with dimensions. The figure is presented in -cut with respect toϕ = 45° in -cut. (c) The symmetrical feed network to divide the signal of one polarization. The figure is presented in -cut with respect toϕ = 45°. (d) Microstripline feed with the stub and the cavity dimensions and (e) the prototype antenna. Dimensions are in mm and all the figures are not in the same scale.
