Thank you Dave , as you have shown .... As Above so Below

----------------- now let us resonate a few Constructs :

Multiband Pyramidal Antenna for Radio Navigation
and Telemetry Systems


Quote:
AbstractA novel multi-band pyramidal antenna combining
radio navigation and MicroSAT telemetry applications was
recently introduced by the authors. This flexible antenna
provides independent and easily adjustable operating frequency
design. Furthermore, the radiation patterns of this pyramidal
antenna are relatively similar at the different operating
frequencies. One key element of this radiating structure is its cutoff
waveguide ( Granite in our case )
placed underneath the antenna ground plane in
order to improve input ports impedance matching while
minimizing the antenna rear radiation level.
This paper further
describes the above-mentioned antenna and gives its latest
improvements.
