Design and optimization of a Yagi-Uda 5G-rejecting TV antenna

This paper discusses the design and optimization of a Yagi-Uda antenna for television (TV) reception that can reject ultra-high frequency (UHF) 5G mobile communication band signals. The antenna presents a high realized gain of more than 10 dBi between 470 and 694 MHz, which corresponds to the UHF TV band and rejects 5G mobile communications signal in the 700 MHz band. The antenna is designed and optimized using CST Studio Suite and it does not utilize an extra filter, relying only on the filtering properties of the structure, especially of the last few director elements.
