Novel TEM Horn Antenna Based on the Linearly Tapered Slot Antenna

A novel TEM horn antenna is proposed by unite its typical structure and the linearly tapered slot antenna structure. The simulation reveals that the proposed antenna performs best in the port matching and has the similar gain with the typical TEM horn antenna, which are much remarkable than those of the linearly tapered slot antenna. Significantly, the proposed antenna can be fabricated based the PCB (printed circuit board) technology which is lower in cost and easier in implement than the typical TEM horn antenna used to be made with complete metal structure.
