Novel band‐notched ultra‐wideband elliptical monopole antenna with dual radiating elements

Abstract

A novel ultra‐wideband design of planar elliptical monopole antenna with dual radiating elements is presented. The proposed antenna consists of two elliptical radiating elements and a ground plane. The antenna has a super‐wideband from 2.8 to 15 GHz for voltage standing wave ratio less than 2, except the notched band at 4.8–5.9 GHz for filtering the wireless local area network signal. Based on the contribution of the shorting position d to the notch bandwidth, a particular notch‐band range can be designed by adjusting the size of the minor elliptical radiating element. The radiation pattern of the proposed antenna in the yz‐plane is omni‐directional. © 2011 Wiley Periodicals, Inc.
