ABSTRACT:
The antenna, particularly for portable televisions, comprises two ports coupled to a radiating element (11), the two ports being placed on the radiating element at 90° to each other and at 45° relative to a horizontal plane. The two ports are linked to a broadband switching and phase shifting circuit controlled in order to supply a polarization diversity signal as output.
