hai all,

I have made one wide band patch antenna(800-2.5GHz), it is working well, now i want to have dual polarization in that like +45 and -45. i will be very glad to have your suggestions.

Thank you

Can you show me your current design?
Please attach the design file or design information.

How are you defining your bandwidth? You are describing about 200% bandwidth if I understand correctly.

That is quite an accomplishment. I would like to know more about your antenna if it does not violate any confidences.

Without knowing your structure suggestions as how to create circular polarization would be pointless. In general, a circular signal requires two equal ( E field) components orthogonal in space and in phase quadrature. Circularly polarized patch antennas often accomplish this with orthogonal feeds.
