Abstract: The invention concerns a planar broadband patch antenna, in particular for transmitting and/or receiving digital and/or analogue terrestrial television UHF/SHF signals, having a bandwidth low frequency tuned reflector and a radiator connected to a specific power supply and radiating in a frequency F1. The radiator also has a slot tuned to a frequency F2. The antenna is characterized in that the radiator has another slot tuned to a frequency F3 different from frequencies F1 and F2, the slots being connected through a linking slot designed to constitute a coupling line to provide a substantially identical electromagnetic current at each of the slots of frequency F2, F3, respectively.
