Abstract
A high gain printed loop antenna comprises a first and second loop arranged symmetrically about a feed network, wherein each of the loops include pairs of substantially parallel radiation sections which when excited in phase from the feed network improves the gain of the antenna. Each of the parallel radiation sections are joined by patch elements such that the width of the patch elements is greater than the width of other portions of the loop. Thus, the patch elements allow for an increased variance in the path of a surface current through the loop.
