Curvature Shape Utilization for Characteristics Enhancement of Skeletal Wire Discone Antenna

Numerous techniques to realize a discone antenna and its enhancements either to improve its performance characteristics or manufacturing process have been reported by academicians and researchers [1]–[3]. A discone antenna, which mainly consists of two parts, i.e., the disc and the cone, was developed by modifying the conventional one using six flared hexagonal panels to reduce the complexity of cone realization [1]. By advantaging a 3D printing technology, a discone antenna based on polylactid acid (PLA) filament has been realized with the reduction in cost of fabrication [2]. While in [3], a skeletal discone antenna whereby the cone part is developed by integrating 3 circular-rings and 8 straight thin copper wires has been characterized experimentally to produce a wideband frequency response.
