“…Wideband stacked patch antenna consisting of 21 layers was reported in [6] for wide scan angle in 4-12-GHz frequency band. Other types of wideband arrays also have been reported, but most of them have limited gain [7]. Manuscript Thus, different antennas for each band or multiband antennas are required to meet bandwidth and gain requirements simultaneously.…”

A high-gain, wideband antenna element that covers most portions of X-and Ku-bands is essential for multimode radar applications. This letter presents an aperture-coupled stacked patch antenna for 8.75-12.25-GHz frequency band. Fixed beam tilt up to 30 in scan range can be obtained by offsetting the aperture relative to a driven patch. When there is no offset, a single antenna has broadside gain greater than 10 dBi. An antenna array (4 4) with fixed beam tilt is designed and validated with measurements. The prototype antenna exhibits 44% fractional bandwidth and maximum gain 20.6 dBi in the target frequency band.
