Wideband antenna
First Claim
1. A wideband antenna, comprising:
- at least one dipole arm base to be received by a ground plane, said at least one dipole arm base supporting a first and second dipole arm each fed by a dipole arm feed, said dipole arm base being dimensioned to provide less than a quarter wavelength separation between said ground plane and said dipole arm, said dipole arm base having apertures to provide a quarter wavelength effective electrical length between said ground plane and said dipole arm feed.

Abstract
Wideband antennas, a wideband antenna assembly and a method are disclosed. One wideband antenna comprises at least one dipole arm base (90A) to be received by a ground plane (80) and supporting at least one dipole arm (20) fed by a dipole arm feed (40), said dipole arm base being dimensioned to provide less than a quarter wavelength separation between said ground plane and said dipole arm, said dipole arm base having apertures (100) to provide a quarter wavelength effective electrical length between said ground plane and said dipole arm feed. Through this approach, it can be seen that the height of the antenna can be reduced whilst still maintaining its correct operation by providing slots to increase the effective electrical length.
