Hello everyone,
I'm designing a dual probe fed patch antenna with air dielectric for the lower GSM band. Although I get a very good radiation pattern and decent return loss, the isolation between the two ports is only about 12 dB at the higher end of the frequency range. The ports are at a distance of 73 mm from each and are a little bit on inside of adjacent edges of the antenna.
I've tried finding literature about the same but couldn't find a dedicated paper or article about improving isolation in dual fed patches.
Any help is appreciated..
Thanks,
Ananth.
