Broadband Dipole Antenna with In-built Balun

Broadband dipole antenna with a built-in balun design for DTV and LAN applications that incorporates a tuning element and balun is presented. The proposed approach, which straddles the gap of the suggested dipole antenna, utilises a unique tuning mechanism. This helps to reduce interference from signals outside the designated digital TV band that would otherwise deteriorate the quality of the DTV signal by allowing the dipole antenna's frequency range to be tuned to narrowly cover the band. The measured findings verify that the suggested antenna covers the frequency band of DTV systems (470-862 MHz) and LAN systems (2.45 GHz and 5.85 GHz). Additionally, the suggested antenna has a maximum realised gain of 2.95 dBi and superb omnidirectional radiation. These outcomes show that the antenna is appropriate for DTV applications.
