What would be a good (free space, 1 GHz) antenna to achieve
circular polarizarion with a nearly spherical coverage?

Thanks,

Sam


Hi Sam

If you want "half spherical" coverage for receiving a circularly
polarized
signal, a turnstile is probably the easiest to build.
If your requirements for sensitivity are more stringent than the
turnstile
provides, a quadrafilar helix is excellant circular polarization.

Hi Jerry,

Unfortunately I am looking for the full sphere :-(

Hi Sam

You may have alot of difficulty locating a design for an antenna that
radiates a given "circular" polarization with "spherical" coverage. I
consider those requirements to be entirely beyond reality. Are you
planning to build this antenna or buy it *off the shelf*?

Jerry

Hi Jerry,

Buy if available, build otherwise ;-((
