چکیده

The hexagonal shaped slotted Wine glass shaped Co Planar Waveguide (CPW) fed antenna for wireless applications is proposed in this paper. The Woodpile based Electronic Bandgap (EBG) structure is used as linked ground surface for bandwidth and gain enhancement. The performance characteristics of different sized strip widths of woodpile structures with wine glass shaped antenna are carried out. The antenna resonates in the band of 2 GHz, 5 GHz and 7 GHz. The band width enhancement of 43 % and gain of 9 dB at 1.9910 GHz for 1mm strip width of woodpile is observed. The group delay variation and E –plane co and cross polarization radiation patterns are also obtained for various strip widths of woodpile structure. The group delay is maintained less than 5 ns and there is significant difference between co and cross polarization for E- plane radiation patterns for 1mm strip width of woodpile structure. The antenna is fabricated with hexagonal slot and 1mm strip width woodpile structure and tested for return loss and radiation pattern.
