Hello,
I am trying to improve Bandwidth of dual coax feed linear polarized antenna on a single patch. I have made a square patch however the bandwidth is quite less. In order to improve it, one way is to make slots parallel to the feed. However since i have two feeds orthogonal to each other, i cant make parallel. So what can be the possible options to address this dual feed issue. The research papers and books i have gone thru addresses single feed antennas by making U shaped slots. I neeed guidance to improve Bandwidth for dual feed. The limitations of design are.... it has to be made on FR4, epsr 4.4, thickness 1.6mm, single patch.
