Abstract :
A novel circular polarized antenna structure capable of high radiation efficiency and suitable for use in multilayer microwave circuits is presented. The antenna uses a low permittivity dielectric layer on top of a high permittivity substrate to enhance radiation. The novel split ring design ensures compensation for the progressive loss in the travelling wave around the ring. Data are provided for a prototype antenna working at 20 GHz.
