A S / X dual broad band patch antenna with shared aperture structure is fabricated. A $2{\times}2$ perforated patch is used for S-band operation and a $2{\times}2$ patch antenna array is integrated in the $2{\times}2$ perforation for X-band operation. The measurement results of a S / X dual broad band patch antenna with shared aperture structure show the broad band characteristics larger than 20 % in both bands.
