[B-1-68] Design of a Center-fed Dual-polarized Parallel-plate Waveguide Slot Array Antenna
Keywords:Dual-polarized antenna、Planar antenna、Parallel-plate waveguide antenna、Slotted array
A dual-polarized paralle-plate waveguide (PPW) slot array antenna operating at 24.5 GHz is presented. In the proposed antenna, two 20$\times$19-element slot arrays are positioned orthogonally to realize dual-polarization. The centered longitudinal coupling slot is introduced into the feeding waveguide, in order to improve aperture efficiency and cross-polarization discrimination (XPD) level.
