“…Moreover, the development of UWB technology promotes further researches on the time-domain characteristics of ultra-wideband antennas. Current ultra-wideband antennas mainly include log-periodic antenna [1], Archimedean spiral antenna [2], equiangular spiral antenna [3], bow-tie antenna [4], tear drop antenna [5], tapered slot antenna [6,7], traditional TEM horn antenna [8][9][10], etc. Among them, traditional TEM horn antenna fails to benefit the integration of communication system because of its stereo-structure with relative big volume and heavy weight.…”

Abstract-In this paper, a new kind of printed TEM horn antenna with high-gain fed by balanced microstrip line is proposed. The radiation part of the antenna (printed on the FR4 epoxy substrate) is composed of two symmetrical triangular metal foil branches fed by balanced microstrip line. The antenna has been simulated by CST MICROWAVE STUDIO software and the simulated results show that the proposed antenna is a kind of traveling wave antenna. Besides, an equivalent adopted V-shaped antenna model is proposed to describe the radiation characteristic of the antenna. The simulated and measured results indicate that in the frequency ranging from 1.64 GHz to 9 GHz, the reflection coefficient of the antenna is less than −6 dB and in the work frequency band, the average gain value is over 8.2 dB. The antenna gain will be improved greatly by extending the length of the dielectric slab appropriately (in the main radiation direction) without influencing the bandwidth. The measured and simulated results have a good consistency. This antenna will have wide application in the UWB field.
