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

1.2 GHz FM Wireless SpyCam
This camera did not include audio, but the circuit board is obviously the same one used for cameras with a mic
10 GHz waveguide slot antenna
A slotted waveguide antenna works by radiating energy from the inside though a number of slots cut in the waveguide
10 Elements Yagi Directional Antenna for 23cm
For ATV transmission in the 23cm band from our club station
20-turn helix antenna for 23 cm
Design of a 10 GHz beacon antenna. A standard WG16 waveguide is used
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
