ABSTRACT:
A multi-band receiving antenna is supported on a windowpane for a radio-receiving set having a single antenna input socket. The antenna has a fishpole-type section which principally contributes to the reception of the metric wave band. A frame section, which runs parallel to the rim of the windowpane, principally contributes to the reception of the medium wave band. Each of the two sections contributes furthermore in a substantial measure, in the order of 10 - 20%, to the reception of signals having a frequency included in the band which is principally received by the other section. The impedance of the metric wave section is adapted by a spirally formed arrangement of the conductor or conductors of the frame portion of the antenna starting from the antenna terminal. The spiral forms an inductance of 0.2 - 0.5 .mu.H over an area of 5 - 15 cm.sup.2. The medium wave section includes a single conductor which runs in close proximity to the rim of the pane or two conductors which run in different directions along portions of the rim. When two conductors are used, the spiral is formed of a double wire.
