ANTENNE FUER EIN FUNKSENDE- UND EMPFANGSGERAET.

摘要

The antenna uses high ohmic resistors (20) or HF choke coils (21) bridging slits (18,19) which divide the conductor paths and surfaces for the telephone circuit into 3 adjacent zones (F1,F2,F3). One of the outer zones (F2) acts as the radiator for the transmission antenna and the other outer zone (F3) acts as the radiator for the reception antenna. The remaining two zones (F1,F3;F2,F3) in either case act as the counter weight. An HF module (17) is pref. positioned above or below the centre zone (F2) of the circuit substrate (10), incorporating an HF transmitter and an HF receiver.
