Re: polarization
vfone, a credit for your explanation about polarization. I was thinking a lot about an answer but your explanation is splendid. I have an additional question about polarization. Let´s say we have to micro_strip antennas with circular polarisations, one for recieving and the other for transmitting . To achive reception, do both have to be RHCP or LHCP ? Can there be one with LHCP and the other with RHCP ? I disregard reception due to reflections.
And to danesh, i really recommend a basic regarding antenna desig by Balanis named ' Antenna Theory Analysis and Design '.
