Development of a 23cm patch antenna


Looking for a robust design for a portable antenna to use with my new DJ-G7E, I decided to try a microstrip patch.This is just a precisely-shaped conductive plate suspended above a ground-plane; but by using PCB techniques, this becomes a simple rectangular "flat-panel" antenna

23 cm Hybrid-Quad von
Some time ago I experimented with double quad antennas in the 23cm band, and I found that the resulting gain in terms of material expenditure is very large, and the broadband nature of such antennas for ATVs is almost the same
