4.5:1 bandwidth microstrip notch array measured performance

The measured performance of a 4.5:1 bandwidth microstrip notch array antenna is presented. This dual-linear polarized array provides orthogonal radiating elements with coincident phase centers. VSWR and gain patterns are presented for individual elements in the array. Pattern data of the array being steered are also presented. This array provides an inexpensive, easy to fabricate solution to wide bandwidth antenna arrays.
