Compact Penta Band Notched Antenna Using Concentric Rings with Splitter Bricks for Ultra Wide Band Applications

摘要

In this paper novel miniature ultra wide band circular mono pole antenna with penta band rejection characteristics is proposed. The antenna is fed through a Coplanar Waveguide (CPW) feed. The antenna is designed using RT/ DUROID substrate with permittivity 2.2. In the proposed antenna Concentric Rings with Splitter Bricks (CRSB) are used to achieve band notching characteristics. It will reject the existing WIMAX (Worldwide Interoperability for Microwave Access) from 3.326-3.612 GHz, C band down link frequency from 3.8-4.2 GHz, WLAN application from 5.393-5.822 GHz, X Band downlink Satellite communication application from 7.25-7.733 GHz and ITU band operations from 8.0-8.565 GHz. The Simulations of this antenna are carried out using CST microwave studio suite 2016. Antenna performance parameters like Return loss, Voltage standing wave ratio (VSWR), Radiation efficiency and Gain are evaluated. Radiation pattern of the antenna at different frequencies are observed. This antenna provides good gain and a larger band width over the frequency range 3.1-11.6 GHz.
