Satellite downlink communication band notched UWB antenna using uniplanar EBG structure

Abstract

Ultra-Wide Band (UWB) antenna with band notch possessions by means of artificial materials is suggested. This methodology makes use of uniplanar Electromagnetic Band Gap (EBG) structure that is capacitively attached to antenna feed to accomplish band-notched designs. One of the compulsory features of uniplanar EBG structures is elimination of perpendicular vias, thus simplifying fabrication method and brands them attuned with microwave and millimetre circuits. Antenna integrated with plus shaped EBG discards the frequency band 7.25–7.75 GHz used for satellite downlink signal. Notch occurrences may be altered by varying the attaching outlines and cavities of EBG cells. The compensations of band notched antenna designs by means of uniplanar EBG structures resembling comfort of production, notch-frequency alteration and stable radiation configuration is also presented. Made-up and tested results are established to be in worthy promise with simulated ones.
