Yagi-Uda Antenna for TV Reception Rejecting 5G Communication Band Signals

This work describes the design and simulation analysis of a high-gain Yagi-Uda antenna with 6 and 10 directors that have been tuned specifically for digital UHF TV reception. The antenna has a novel design that can successfully reject interference from 5G mobile communication low band signals. The fast deployment of 5G networks has resulted in significant electromagnetic interference, adversely affecting television reception. In order to address this growing challenge, the proposed antenna acts as an efficient band-stop filter. The filtering effect depends on the relative position of the driven element and the spacing between directors. This reduces the need for extra filtering components and is tuned specifically to reject frequencies that are linked with 5G mobile communication signals. Simulations indicate that the antenna reaches a peak realized gain of 16.3 dBi, hence improving directional signal reception and significantly mitigating interference from adjacent frequencies.
