Abstract Based on optimized geometry structure of tapered slot antenna, an end-fire printed antenna is designed with rectangular-grooved and periodic structure. Its effects on the radiation pattern of antenna is studied and simulated. From 1 GHz to 3.5 GHz, those structures improve the end-fire characteristics of the antenna obviously. Finally, pairs of antennas are constructed and measured. The measured results show that VSWR is smaller than 2 and the gain is approximately equal to 7 dBi from 1 GHz to 3.5 GHz. The measured transfer characteristics results show that the antenna achieves a stable group delay and a low late-time ring. The antenna can be applied to the impulse radar.
