Abstract
A miniaturized radio antenna element for use at VHF and UHF is designed to operate well short of resonance. It comprises a small flat cavity in the surface of which is formed at least one radiating slot very much smaller than a normal resonant slot. However, an impedance matching circuit is often required at the ports of this antenna.
