antenna dual polarization
Recently I read a dual polarized antenna and have some questions to ask, the structure of the antenna is as follows:
As the author said, the patch antenna is orthogonally fed by two CPWs, the antenna can work at 2.45GHz with the two polarizations simultaneously, with high port isolation. And the proposed antenna has smaller size than two single polarized antenna working at the same frequency.
But I think when the two ports are simultaneously excitied at 2.45GHz, the current flowing on the patch will be a totally new distribution rather than a simple superposition, and forms a new polarization (not an addition of the two orthogonal polarizations). And this one patch antenna can not be compared with two single antennas at one frequency, they are totally different in nature.
I do not know if I am right. What is your opinion?
Thank you!
