Advanced Radar Programs use low sidelobe, wide angle scan active aperture arrays over a broad bandwidth to ensure the frequency agility and ECCM requirements of modern day radar systems. The design of such a high performance, cost effective active aperture array within the weight, size and volume constraints is very critical right from choosing the array grid architecture, radiating element structures...

A new compact planar microstrip antenna element is reported for active phased array applications. The element has been designed in S-band frequency with a wide beamwidth better than 120 degrees. The antenna element gives a VSWR of 1:2 over a bandwidth of 11% in S-band. The element is fabricated on a low cost glass epoxy (FR4) substrate for cost effectiveness.
This paper presents design and development of a light weight and low profile microstrip antenna array meant for a ground based surveillance radar. The array has been configured to form shaped and narrow beams in elevation and azimuth planes, respectively. Array has performed satisfactorily producing a minimum gain of 24 dB and sidelobe level of -25 dB in azimuth plane and shaped beam coverage beyond...
