Abstract
Official abstract text for this publication.
The subject of this invention is a multiband antenna radiating element comprising a first pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a first radiating plane corresponding to a low frequency band. The radiating element also consists of at least a second pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a second radiating plan corresponding to a higher frequency band. The first and second radiating planes are parallel; the second radiating plane is positioned above the first from which it is electrically insulated and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is larger than the surface of the second radiating plane covering the conducting arms of the second pair of dipoles. The first radiating plane can be defined by a first pair of dual cross-polarization dipoles or one printed circuit dipole and the second radiating plane can be defined by a second pair of dipoles chosen from cross dipoles, butterfly dipoles and printed circuit dipoles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A radiating element for a multi-band antenna, the radiating element comprising: a reflector oriented to lie within a reflector plane; a first pair of dipoles, each dipole of the first pair of dipoles having two collinear conductive arms, the dipoles of the first pair being oriented orthogonally relative to each other and to lie substantially within a first radiator plane; and a second pair of dipoles, electrically insulated from the first pair of d…
