C Network Base Station Antenna Array And Front-end Lna Simulation Design And Analysis Of Research

In the cellular mobile communication(CMC),it is to set up a wireless transmission between the base station (BS) and the mobile station(MS) served in the field to the antenna for BS. In the physical parts of the air interface, a communication between BS and MS has to be equipped with BS antenna to do. And, the other part of the transceiver , low noise amplifier (LNA) is a next one under a antenna as the first part of signal procession. They are all critical for a system.The article is based on the project in a corporation, including the first segment, which are calculation , simulation and analysis for BS antenna array, and second one, which are design, obtaining the simulation result and measurement.In the first segment for antenna design, the antenna unit structures and its parameter are analyzed. It is illuminated for the reason to a unit slice , opened stub analysis, and Green function for microstrip antenna analysis exactly.The next step is mainly followed by comb antenna array design. After the comparing among the structures, one has been selected and analyzed with its equal circuit. Then, practical design has been taken , simulated for the schematic. Finally, analysis of the result is taken with a good comparing.The second portion focus on the designed of a LNA. The reason of a structure selection, some components selection for the system is narrated. Then, the circuit is designed concretely, including adjusting and practical effects. As the result is obtained, the practical measurement is compared with it, show a favorable satisfaction.
