- Design and implementation of a 3D printed discone antenna for TV broadcasting systemPublication . Gonçalves, Ricardo; Pinho, Pedro; Carvalho, NunoDiscone antennas are wide bandwidth and omnidirectional radiation antennas that are widely used in VHF and UHF broadcasting systems. This paper presents the design and implementation of a discone antenna, for indoor use in a digital TV receiving/transmitting system, which was developed using 3D printing technology, allowing the development to be simple, quick and less expensive. The antenna presents a measured matched bandwidth, below - 10dB of return loss, between 380 MHz and 3 GHz. Simulation and measurements match, with the antenna presenting an omnidirectional radiation pattern within the considered TV band.
