Study Of The 4ports 4polarizations Base Station Antennas For PHS

The rapid development of the world communication service has brought the demand of high quality communication equipments. Antenna is an important part of the communication base station. It takes on signal reception and transmitting. Along with the increase in telephone number, completion rate's dropping off, call-drop will ascend. So the quality of the network is confronted with proof.Antennas function in network optimization in PHS and improve the SNR. To improve the quality of the network, to operate perfectly, and to pursue the perfect quality of the communication, we can not build base stations at random but design better base station antennas, which is one part of the study on the network optimization.In this paper, we mainly study on the base station antenna. On the base of theory, we make software simulations and conduct experiments on the design. Introduced the technique of diversity reception, we devise PHS 4ports 4polarizations antenna with 6 sides configuration and the antenna take on a good action.The main contents in this paper are:1. Design dual-polarization base station antenna units2. Simulate on the arrays and conduct experiments3. We can be familiar with analyzing the radiation pattern through comparing with the horn antenna4. Analyze the measured result...
