Abstract
A broadband helical microstrip antenna having a small foot print is disclosed. A PCB (printed circuit board) has a first planar side opposite a second planar side with dielectric material therebetween. The first planar side comprising a plurality of spaced apart non-linear antenna segments, each non-linear antenna segment having one or more electrical vias to the second planar side of the printed circuit board. The second planar side comprising a plurality of spaced apart parallel linear antenna segments. The plurality of non-linear antenna segments and the plurality of linear antenna segments form the broadband helical microstrip antenna symmetrical about a center line formed by a centered linear antenna segment of the plurality of spaced apart parallel linear antenna segments of the second planar side.
