Compact portable antenna for terrestrial digital television
Abstract:
The present invention relates to a portable compact antenna formed from a first dipole type element operating in a first frequency band and comprising a first and at least one second conductive arm, differentially supplied, the first arm or cold arm forming at least one cover for an electronic card and the second arm or hot arm being constituted by a U-shaped conductive element realized on an insulating substrate. Further, a radiating element with bends is realized between the branches of the U-shaped element and is dimensioned to operate in a second frequency band.
