Corner Truncated Triple Band Notch Monopole with DGS for Satellite Communication Applications

Abstract

A Compact triple notch band monopole antenna with defected ground structure is proposed in this article. Corner truncated square radiating element on the top side and defected ground structure on the bottom side are placed on FR4 substrate of permittivity 4.4. An inverted U-slot is placed on the feed line to have proper impedance between feed point and the ground plane. The proposed antenna providing triple notch band characteristics between 7-7.4 GHz, 8-12 GHz and 16-18 GHz respectively. The fabricated antenna occupying the dimension of 24X26X1.6 mm and the measured results providing excellent correlation with simulation results.
