Patent ID: 7969373

Claim:
Planar antenna device for an electronic device characterized in that it comprises: i) a loop antenna with a chosen shape and comprising first and second ends spaced one from the other, ii) a tuning means connected to said first and second ends and arranged to control the frequency of the VHF TV signals said loop antenna is able to receive from command signals, iii) a first ground plane coupled so as to cooperate with the loop antenna in order that it acts as a UHF monopole for receiving TV signals having UHF frequencies, iv) a first coupling means coupled to the loop antenna at a first chosen location and arranged to deliver the received TV signals having VHF frequencies, v) a second coupling means coupled to the loop antenna at a second chosen location and arranged to deliver the received TV signals having UHF frequencies, vi) an amplification means coupled to the first ground plane and arranged to amplify TV signals, and vii) a switching means arranged to couple the amplification means to the first coupling means and/or to the second coupling means in dependence on command signals, such that the amplification means delivers amplified selected TV signals having VHF and/or UHF frequencies to an output.
