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

Thanks,

Near 1.5 Ghz the "Patch" antenna works well for me and my GPS receiver. I
THINK it is CP but which rotation??? Some sources indicate you have to nick
alternate corners of the radiating element to achieve CP. I don't know.

Google .com tells me the GPS patch is available at

or a 2.4 GHz version at http://www.rc-cam.com/gp_patch.htm#GPP_faq

You scale it to your approximate center freq. Good luck
