In this paper, three types of novel bowtie antennas with round corners are presented and studied carefully, including quadrate, rounded-edge and triangular shapes, which have better return loss, flatter input impedance, more stable radiation patterns and smaller area at the same time. The effect of round corners is attached importance to due to their novelty. The conclusion is drawn that adding the round corners at the sharp vertexes of radiation surfaces can have positive effects on performances of not only bowtie antennas but also the others.
