1) What's the difference between omnidirectional antenna and the normal UHF antenna? What I know is there are 2types of antenna in RFID implementation; linear polarized and circular polarized. Does omnidirectional refers to circular type antenna?
2) Is the calculation for EIRP / ERP the same for linear and circular polarized antenna?
3) Near field vs far field antenna / reader, do they come with linear polarized and circular polarized or does it use a different kind?
4) As for the combination of tag antenna and reader antenna, I heard that if the tag antenna is circularly polarized then it would be best to use a circular polarized antenna for the reader als. Is this true?
