Hi Egliu,
I've designed and measured patch antennas at 1.5 GHz, 5 GHz and "conventional" patch antennas at 1.5, 2.4, 5, 10 GHz both in Linear and Circular Polarization
At the moment, I'm involved both in probe-fed slotted microstrip antennas and "contact-less" patch antennas.
I'ld like to share my results with yours for the same type of antenna in terms of Impedance Bandwidth, Polarization Bandwidth and so on...
What do you think?
Then, for what concerns contact-less excitation, I'm studying a patch antenna capacitive-coupled at 3 GHz in LP. What about you? Can you give more informations about your design? We can exchange observations.
Do you have material or articles about it? (not IEEE)
Regards
Lupin
