Abstract (en)
[origin: US6342855B1] The invention relates to a planar antenna (1), in particular for mobile radio, the planar antenna (1) having two conductive layers arranged at a predefined distance from one another, the conductive layers being plates (2, 12, 20, 20'; 3, 13, 30, 30') or sheets which are plane-parallel with one another, the first layer (2, 12, 20, 20') having a surface that is symmetrical with respect to a symmetry axis (15) and the second layer (3, 13, 30, 30') being a subregion of the surface of the first layer, the second layer being formed by reducing, or respectively cutting off or leaving out a part of the first area along a straight line or chord (4, 14, 40, 40') extending at right angles to the symmetry axis (15), and the chord of the second layer forming a rectilinear edge, and the two layers being conductively connected to one another, the conductive connection being made by pointwise-arranged or strip-like connection elements (15, 19) on the border (8, 18) of the layers which is remote from the chord (4, 14, 40, 40').
