Abstract
The addition of an annular short-circuited ring to a microstrip disc has resulted in a novel compact antenna suitable for reflector feed applications. Variations of the ring geometry allow bandwidth extensions up to twice that of the disc, but with some gain penalty. The radiation pattern has good circular symmetry and a reduced crosspolarisation of ¿21 dB compared to the isolated disc.
