    dual circularly polarized antenna with branch line coupler feed

    I think if cross-polarization levels are good, then beams should be more or less independent.

    dual circularly polarized antenna with branch line coupler feed

    just to make sure I get this right. If there is sufficient isolation between LH and RH ports, then you can transmit/receive two independent beams in LHCP and RHCP at the same frequency?

    dual circularly polarized antenna with branch line coupler feed

    Hi all, I'm some what confused about dual polarized antennas. In some cases it is concurrent dual polarization, while in others it is switchable between the two polarizations. Take this example with branch coupler feeding each antenna and four antennas arranged in sequential rotation feed...
