Abstract


With the development of mobile communication base station antenna is also the ever-increasing demands . Requires not only having a wider frequency band or a plurality of bands , but also have a higher gain , a good pattern , etc., while the volume is as small as possible in terms of structure , the structure is as compact as possible in order to reduce the drag , reducing installation time environmental requirements. The first two chapters of this article reviews the course of development of the mobile communications and antenna theory and used simulation software HFSS the theoretical basis of the finite element method to do a simple introduction . The third detailed in chapter covering the design of broadband dual-polarized base station unit CDMA800MHz/GSM900MHz through simulation and actual test proved that it has good voltage standing wave ratio , isolation , pattern , and gain . While the unit is casting process, compared with ordinary microstrip unit , lower cost , structural stability , and third-order intermodulation better . Final chapter Taylor consolidation method , designed an eight- unit inclination of 4 degrees electric array antenna through the test indicators fully meet the mobile communication requirements .
