Abstract
An antenna array () for detecting an incoming radio wave () having an operating wavelength, comprising: a plurality of antenna elements () arranged in an array with a periodic repetition of the antenna elements (). Each antenna element () comprises a slot () being shaped such that the polarisation of the corresponding antenna element () is non-linear, and having a first axis (A) and a second axis (A) orthogonal to the first axis. Each of the first and second axes (A; A) has a length in the range of about 0.05-0.2 times the operating wavelength of the incoming radio wave () and the ratio of the length of the first axis Ato the length of the second axis Ais between about 1-2.5. There is also a method of configuring an antenna arrayfor detecting an incoming radio wave (), and a method of determining the angle of arrival of a radio wave () impinging on such an antenna array ().
