Claim 1
Independent Claim
209 words
In a multi-band receiving antenna supported on a windowpane having a rim and suitable for a radio-receiving set having a single antenna input terminal, which antenna includes a fishpole-type section which prevalently contributes to reception of the metric wave band and which is connected to the terminal and a frame section which runs parallel to the rim of the windowpane and prevalently contributes to reception of the medium wave band, the improvement wherein said frame section consists of a single conductor having a free end and running along parallel to and in close vicinity from said rim, and means for adapting the impedance of the metric wave section comprising a spirally formed conductive extension of said single conductor of said frame section of the antenna connected between said terminal and said single conductor, such as to form an inductance of from substantially 0.2 to substantially 0.5μH over an area of from substantially 5 to substantially 15 cm 2 , said free end of said single conductor terminating in the vicinity of said spirally formed extension, whereby each of the sections contributes in substantial measure, in the order of 10 to 20%, to reception of signals having frequencies included in that band which is prevalently received by the other section.
Claim 2
Dependent Claim

In a multi-band receiving antenna supported on a windowpane having a rim and suitable for a radio-receiving set having a single antenna input terminal, which antenna includes a fishpole-type section which prevalently contributes to reception of the metric wave band and which is connected to the terminal and a frame section which runs parallel to the rim of the windowpane and prevalently contributes to reception of the medium wave band, the improvement wherein said frame section consists of a single conductor having a free end and running along parallel to and in close vicinity from said rim, and means for adapting the impedance of the metric wave section comprising a spirally formed conductive extension of said single conductor of said frame section of the antenna connected between said terminal and said single conductor, such as to form an inductance of from substantially 0.2 to substantially 0.5μH over an area of from substantially 5 to substantially 15 cm 2 , said free end of said single conductor terminating in the vicinity of said spirally formed extension, whereby each of the sections contributes in substantial measure, in the order of 10 to 20%, to reception of signals having frequencies included in that band which is prevalently received by the other section.
Claim 3
Dependent Claim
53 words
An improved multi-band antenna according to claim 1, wherein said single conductor running along in parallel to said rim of said windowpane includes a first portion and a second portion, said second portion consisting of a portion of said single conductor running in parallel to and in close vicinity from said first portion.
Claim 4
Dependent Claim
32 words
An improved antenna according to claim 2, wherein the conductor forming said frame section of the antenna is spaced from approximately 7 to approximately 10 cm from said rim of said windowpane.
Claim 5
Dependent Claim
32 words
An improved antenna according to claim 1, wherein the conductor forming said frame section of the antenna is spaced from approximately 7 to approximately 10 cm from said rim of said windowpane.
