Design of simple and high performance antennas for polarization diversity

Abstract

A wideband dual-polarized with a simple structure is investigated. The title of the antenna is called “Design of simple and high performance antennas for polarization diversity”. By using the L-probe coupling technique and the counteract technique together with the simple structure, a wideband dual polarized antenna with high isolation (S12<-30dB, 0.82-0.96GHz) is fabricated and test. The proposed antenna is suitable for the CDMA800 and GSM900 for mobile communication. By using simple structure, it can help to decrease the coupling effect in between the two L-shaped probes, help to achieve high gain, good matching result and it would be time saving and less working procedure than fabricate a network to achieve the same result. Moreover, my proposed antenna was added with a Wilkinson power divider which can be function in CP (circular polarized) for satellite communication. Finally, the techniques of my antenna are seldom be used, so I would write a Paper to IEEE for the performance of my antenna.
