Dual Band Patch Antenna

I have seen a couple of the examples on here and the web. I wanted to design a dual band patch at 915MHz and 2.4GHz but it doesn't seem like any of the designs I have seen can work with such a large delta freq. Is there a design I have overlooked? Or do I just need to give up and try other ideas.

Re: Dual Band Patch Antenna

I think I have seen this paper. I was looking for a design that is microstrip feed not feed directly by a coax. But thanks fro the help.

The design is to broadband I think. I really only need two selects frequencies.

Part about Dual Frequency Microstrip Antenna you can find in book "Compact and Broadband Microstrip Antennas" by Kin-Lu Wong. And you also can look attached presentation. Maybe PIFA design is suitable for you.
