Improved Performance of the Basic Array of a Microstrip Adaptive Antenna using a Tree Structure of Patch Fed by Electromagnetic Coupling
نویسندگان
چکیده
The aim of this investigation is to improve the performance of a basic microstrip antenna array using a tree structure patch supplied by electromagnetic coupling. The developed network which contains two subnets, a distribution subnet and a scanning subnet, is considered as a first step to design an adaptive microstrip antenna for UMTS use. The patch distribution structure used in this experiment allowed a great improvement of gain, directivity as well as the adaptation level of the studied array. The following work was realized in the laboratory signals, systems and components of FST-Fes, in colaboration with the Microwave Laboratory of the National Institute of Posts and Telecommunications of Rabat. Keywords—microstrip antenna array; electromagnetic coupling; adaptive microstrip antenna; tree patch distribution structure.
