ANTENNA ARRAY - UNIV MALTA

Title:

ANTENNA ARRAY

Document Type and Number:

WIPO Patent Application WO/2015/019084

Kind Code:

A3

Abstract:

An antenna array has a plurality of elements including at least one of a first type and at least four of a second type. The element of the first type (12) comprises part of two seeds (20, 21) with two elements (13,16) of the second type, and is capacitively coupled to two further elements (14,15) the second type. The elements may each comprise a plurality of hollow sub-elements, arranged one within the other, to define openings in each element between the sub-elements. Alternatively, or in addition, the antenna may include a ground plane separated from the planar element array and a frequency selective surface formed by a resistive component on a layer of dielectric material, between the planar element array and the ground plane.
