Abstract:

A planar two-dimensional reactively steered adaptive array which includes a single active microstrip element and eight closely coupled parasitic strip elements has been designed and tested. Steering of a null towards a single incident jammer is accomplished by adaptive control of reactive terminations on the parasitic elements using a guided random search algorithm. The planar array can steer a null in both the elevation and azimuth directions with a depth of 30 decibels.
