<p>A first planar printed circuit board and a second planar printed circuit board are assembled to intersect each other at right angles to each other. Each board includes a microstrip realization of a drooping dipole antenna. The realization comprises, for each planar board, two vertical parallel feed lines with a radiating element extending from each feed line. Each of the feed line is fed 90.degree. out of phase with the other feed line on the same board.</p> |
