Hi, guys!
Have somebody worked with UHF chip having two antenna connected to two different port? I obtained increment of read range about 1.4 times (near to theory ) using two orthogonal straight dipole, but using dipoles of different form led to essential decreasing of read range. I think...
Thank you for the reference, I have found some useful information about patch antenna structures, design methods and CAD software. But unfortunately, I have not found any information about historical development of patch antennas.

Hi!
During simulation of a PIFA antenna (see fig. 1) I had a question: what is difference between theta component and X component when, for example, a directivity DirTheta and DirX (see fig. 2 and 3) is plotted? These components is codirectional. Why diagrams is different?
