A wideband, low profile P- and Ku-band Dual Polarized shared aperture antenna

This paper focuses on a design to integrate P-band and Ku-band antenna in a shared compact planar aperture. The antenna consists one antenna element for P-band and a 8 X 8 planar array for Ku-band. To share the same radiation aperture, the Ku-band antenna array is placed on the P-band patch. This means that the P-band patch serves as both the radiation patch in P-band and the reflector plane in Ku-band. To obtain a wide bandwidth, stacked patch antenna is selected for Ku-band and L-probe feeding is selected for P-band. The antenna is analysed with HFSS software and the simulated results are presented.
