Abstract

This short communication presents the design, fabrication and the measured results of a stacked array antenna for X-band radar applications. The antenna array is comprised of 2 × 8 radiating elements to produce a fan beam which is narrow in the azimuth and wider in the elevation. The individual radiating elements of the array utilize a stacked patch topology to achieve broad bandwidth and high gain. The array elements are pin fed from a microstrip corporate feed network designed on a substrate placing beneath to conserve the broad space. The simulation results show that the individual radiating element operates from 10.0 to 10.6 GHz with − 10 dB return loss bandwidth of 600 MHz, and realized gain of 6.3 dBi. A 2 × 8 array is then fabricated. The measured results show that the antenna has Phi-0 beam width of 10° and a Phi-90 beamwidth of 30° with 17.1 dBi boresight gain. The antenna is suitable for X-band applications like amateur radio, amateur satellite, military, airborne and naval radars.
