摘要: A novel planar tapered-slot-fed annular slot antenna is proposed in this paper. The utilizes a unique tapered-slot feeding structure and simultaneously possesses ultrawide bandwidth, almost uniform radiation patterns, low profile. It is, hence, adequate for ultrawide-band (UWB) applications. By means of normalized transfer function, both frequency domain time characteristics the are carefully investigated. Two measures, uniformity related to patterns fidelity associated with transient behaviors, used quantitatively describe performance an over such bandwidth. Effects varying antenna's geometric parameters on then Finally, influence minimizing dimension discussed at end
