چکیده
|
Design and implementation procedure of a wideband aperture coupled microstrip antenna in l-bandfrequency is introduced. to improve radiation performance of the microstrip antenna four structures are proposed.the measurement and simulation results show better performance in terms of matching bandwidth for the structureconstructed with air substrate. experimental results of frequency bandwidth and radiation patterns of the optimumstructure are in agreement with the simulation results. the proposed patch antenna creates a directive radiation pattern with a gain of 8.5db. in addition, it provides a quite large frequency bandwidth of greater than 25%, and f/b better than 15db as well. this aperture coupled microstrip antenna has been used as an element of 8×1 microstriparray antenna for ssr systems. the array antenna gain, sll and azimuth hpbw are: 17.5db, less than 24db and10°, respectively.
