Abstract :
A novel uniplanar coplanar waveguide-fed quasi-Yagi antenna is presented. The originality of this design is because of its feed selection and its elliptical structure and in doing so achieving a wide bandwidth and compact size. An X-band prototype is developed and measures a bandwidth of 40%, with 3.2 dBi gain and 11 dB front-to-back ratio measured at 10 GHz. The antenna is realised on a high dielectric constant substrate and is compatible with monolithic microwave integrated circuits and solid-state devices
