Title: Wide band antenna array
Inventor: HILL DAVID ROY
IPC: H01Q11/10
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To provide an asymmetrical logalithm cycle dipole array by which a grating lobe is restricted without limiting the interval of element by permitting the respective poles of an asymmetrical dipole to be asymmetric, permitting the lengths of the end parts of the dipole to be equal and permitting angles to be the prescribed one against the center part of the dipole so as to execute formation. SOLUTION: The individual dipole is arranged in, for example, a Z-shape, that is, asymmetrically. The angles β between the end parts and the center part are mutually equal and the asymmetric dipole is perfectly included in one planar area. The angles β is 90 deg., for example. Then, the whole center parts of the dipole is the same in length and is equal to semi-wavelength in a highest frequency operation. In this case, the lengths of the two end parts 21a and 21b of the asymmetrical dipole 21 by 90 deg. are equal. Thus, the width of the logarithm cycle dipole array is fixed and adjustment is executed by the highest frequency operation regardless of the request of band width.
