Abstract

In this paper, a wideband dual polarization L/X-band shared aperture antenna is presented. As the frequency ratio is about 8, the configuration of perforated patch and patch antenna is selected. To increase the bandwidth, stacked patch antennas are used for both Land Xbands. The antenna consists of one antenna element for L-band and an 8x8 planar array for X-band. To obtain good patterns over the whole frequency band, corporate feed network is used in the X-band array. The element with high isolation and low cross polarization characteristics introduced in [6] was used in the X-band array.
