Abstract :
A new design of circularly-polarised square microstrip antenna fed along a diagonal with a pair of suitable chip resistors located alone the centreline is presented. This design provides a wider bandwidth for circular polarisation radiation about two times that of a similar design with a pair of shorting posts. Details of the antenna design and experimental results are presented
