Wideband antenna using bow tie shape with incision Gap for DVB-T2 application

摘要

This paper presents a unidirectional bowtie shaped antenna with incision gap for DVB-T2 application. The antenna consists of a bowtie radiator with incision gap on top of a square reflector. The simulated and measured results of the antenna show a good impedance matching for |S11| of less than -10 dB along a frequency range of 450-1080 MHz (82.35%). The measured gains are 6.10-8.42 dBi along an operating frequency of 470-862 MHz with the half-power beamwidth in the vertical plane of 83.5°, 98° and 127.5° and the half-power beamwidth in the horizontal plane of 60.5°, 54° and 94° at the frequency of 470, 666 and 862 MHz, respectively.
