Design of L-band High Gain Array Antennas Based on Microwave Network Theory

WANG You-bao;ZHENG Guo-qing;GU Meng-yun;Research Center of Applied Electromagnetics,Nanjing University of Information Science & Technology;  
Based on the microwave network theory,two L-band array antennas with 4 and 16 elements are designed in the paper,respectively. It's applied to the receiving antenna of meteorological sounding meter so that the receiver is of complanation and miniaturization. In order to get the feed network of the higher gain antenna array,the coupling effect between antenna elements,the amplitude and phase of each antenna element are all taken into consideration by the application of microwave network scattering matrix theory. The simulation results of the designed array antennas are consistent with the test results. At 1. 68 GHz,the maximum gain of the 4-element and16-element array antennas are 10. 4 and 15. 6 d Bi,respectively. The two antenna arrays meet the design requirements and can be used in the field of meteorological detection.
