CPW-Fed Triple High Rejection Notched UWB & X-Band Antenna on Silicon for Imaging & Wireless Applications

摘要： In this paper, compact Coplanar Waveguide feed antenna covering UWB & X-Band signals (2.98GHz-13.34GHz) is presented. Antenna also offers triple notched band elimination (WiMAX: 3.40GHz-3.95GHz, WLAN: 4.50GHz-6.34GHz & Downlink Satellite System: 7.11GHz-7.802GHz) which are due to insertion of stub and etching of slots. Antenna is fabricated and characterized on silicon for imaging and wireless applications with having fractional bandwidth of 133%. The antenna offers gain, radiation efficiency and group delay between 3.26dBi-8.00dBi, 84%-92% and ≤ ±1.0ns respectively for the entire of its bandwidth. Isolation of antenna in face to face and side to side orientations are < -25dB with very less distortion presented in the transmission and reception of the signal. The radiations emitted by the antenna are observed as dipole like pattern in E-plane and omni-directional in H-plane.
