Abstract :
This work has developed an ultrawideband tapered slot antenna in the frequency range from 2.2 GHz to 8.5 GHz. High directivity is achieved by using a dielectric rod as a waveguide and a metallic reflector. The antenna exhibits a stable main beam direction over the band of operation and a measured mean gain of 8.1 dBi. At 5.5 GHz, a 3 dB opening angle of 42deg and a front-to-back ratio better than 14 dB were realized.
