Abstract

In this paper, the concept of a current sheet array (CSA) is expanded to design a broadband bowtie-shaped antenna array. The present approach has the potential to achieve a 7:1 bandwidth over the VHF and UHF frequency bands with wide-angle beam. A 3 by 3 array of overlapping bowtie-shaped elements, with center feeding, was simulated. Printing was carried out on both faces of the dielectric slab and kept at a defined distance from the ground plane. A selected design was fabricated and tested experimentally to verify the simulated results for concept validation.
