Abstract
Abstract A multiband antenna for window panes includes a frame-type antenna component and a fishpole-type antenna component. The two components have a common output terminal. The fishpole component is free of any cross bar. At least one leg of the frame-type component which runs along the lower rim of the window is provided with a succession of horizontally directed S-shaped loops, each loop having a length corresponding to an uneven multiple of wave lengths corresponding to the central frequency of the metric band.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A multiband antenna for window panes, the antenna comprising a fishpole-type antenna component and a frame-type antenna component having a common terminal, at least one leg of said frame-type antenna component bordering one window rim and including a succession of series-connected horizontally directed S-shaped loops in a single conductor adjacent said one window rim, each said S-shaped loop having a length corresponding to an uneven multiple of a quarter wave length corresponding to the central frequency of the metric wave band.
Claim 2
Dependent Claim
81 words
A multiband antenna for window panes, the antenna comprising a fishpole-type antenna component and a frame-type antenna component having a common terminal, at least one leg of said frame-type antenna component bordering one window rim and including a succession of series-connected horizontally directed S-shaped loops in a single conductor adjacent said one window rim, each said S-shaped loop having a length corresponding to an uneven multiple of a quarter wave length corresponding to the central frequency of the metric wave band.
Claim 3
Dependent Claim
42 words
A multiband antenna according to claim 1, wherein said frame-type antenna component consists of a single conductor starting from said terminal common with said fishpole-type antenna component and bordering all rims of said window pane to end short of said common terminal.
Claim 4
Dependent Claim
75 words
A multiband antenna according to claim 1, wherein said frame-type antenna component consists of two conductors, each said conductor starting in opposite directions from said common terminal positioned on the lower end of said fishpole-type antenna component and bordering one half of the window rims to end short of the upper end of said fishpole-type antenna component, the lower leg of each said conductor forming a respective succession of said series-connected, horizontally directed S-shaped loops.
Claim 5
Dependent Claim
27 words
A multiband antenna according to claim 1, wherein said fishpole-type antenna component has a single end unconnected to said common terminal and free of any cross bar.
Claim 6
Dependent Claim
27 words
A multiband antenna according to claim 2, wherein said fishpole-type antenna component has a single end unconnected to said common terminal and free of any cross bar.
Claim 7
Dependent Claim
27 words
A multiband antenna according to claim 3, wherein said fishpole-type antenna component has a single end unconnected to said common terminal and free of any cross bar.
