Bowtie array
WebA batwing or super turnstile antenna is a type of broadcasting antenna used at VHF and UHF frequencies, named for its distinctive shape which resembles a bat wing or bow tie. Stacked arrays of batwing antennas are used as television broadcasting antennas due to their omnidirectional characteristics. Batwing antennas generate a horizontally polarized … WebFeb 6, 2024 · A tightly coupled bowtie array antenna at a millimetre-wave band is presented in the study. The antenna has a simple structure and exhibits a high performance over an ultra-wide bandwidth. The feeding network is designed by using the dielectric-based inverted microstrip gap waveguide technology in order to have a compact layout. An 8 × …
