MOBILE TELEPHONE WITH A BUILT-IN PLANAR TELEVISION ANTENNA ADAPTED FOR RADIOTELEPHONE SIGNAL REJECTION

摘要

A mobile telephone comprises a casing housing a telephone set to receive and transmit radiotelephone signals and a television set comprising a main television antenna (MAN) to receive radiotelevision signals, a television receiver arranged to process the received radiotelevision signals to output television signals to be displayed, and a display means to display the outputted television signals. The main television antenna (MAN) is made in planar technology, is built-in inside the casing and comprises a filtering slot (FS) having chosen dimensions (Dl, D2) to be resonant around the frequency of the radiotelephone signals to reject them at least partly.
