First Claim
Patent Images
1. A microstrip crossed-drooping dipole antenna arrangement, comprising:
- a first planar printed circuit board and a second planar printed circuit board, said boards being assembled to intersect each other at right anles to each other;
each said board comprising a microstrip realization of a drooping dipole antenna;
said realization comprising, for each planar board and on one side of said board, a first vertical feed line and a second side-by-side vertical feed line;
a first radiating element extending from said first feed line on the side of said first feed line opposite said second feed line and a second radiating element extending from said second feed line on the side of said second feed line opposite said first feed line;
a ground plane on each said board comprising a conductive pattern formed on the other side of said board; and
means for feeding said feed lines of said first and second boards such that they have a nominal 90°
phase relationship with each other.

Abstract
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 lines is fed 90° out of phase with the other feed line on the same board.
