Abstract
A multi-band windshield or window antenna has a fishpole-type conductor for metric wave band signal reception, the fishpole-type conductor having a free upper end, which may be split or folded back upon itself. At least one second conductor is provided for the reception of medium wave band signals. Each second conductor is connected to a common terminal with the fishpole-type conductor, extends along adjacent at least a portion of a first horizontal rim of the windshield, is bent back upon itself, extends vertically parallel to said fishpole-type conductor, horizontally adjacent to a second horizontal rim of the windshield and then vertically adjacent to a vertical rim of the windshield.
Claims11
In a multi-band windshield or window antenna having a fishpole-type conductor for metric wave band signal reception and having a free upper end portion extendng to a given level, and at least one conductor running along in close vicinity to a periphery of the windshield or windowpane for the reception of medium wave band signals, all conductors conjoining at a common terminal located adjacently to a first rim of the windshield or window, the improvement wherein each conductor for medium wave signals extends in a generally horizontal direction from said common terminal for a distance adjacent said first rim, then doubles back on itself to form a first loop, at the end of which it bends upward into a generally first vertical leg running parallel to and in close vicinity to said fishpole-type conductor, until substantially reaching said given level of said free end portion of said fishpole-type conductor, to bend thereat away from said fishpole-type conductor and run along adjacent to at least a portion of a second rim of said windshield or window, and then bends downwardly and extends toward said first rim, running along adjacent to a third rim of said windshield or window to define a second vertical leg, whereby the at least one conductor for the reception medium wave band signals also participates in picking up of the metric wave band signals and the fishpole-type conductor also participates in picking up of the medium wave band signals.
