BROADBAND DIPOLE ANTENNA WITH INBUILT BALUN

SSRN Electronic Journal
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
