Array antenna having pairs of antenna elements |
摘要 |
An antenna apparatus capable of generating scanning beams through a range of 0°-90° is provided. The antenna apparatus includes one or more rows of antenna elements, with the antenna elements in each row being arranged in pairs. The elements within a pair are separated by a distance of about lambda/four, and the pairs are separated by a distance of about lambda/two, where lambda is the wavelength of the center frequency of signals transmitted from the antenna apparatus. Transmit/receive circuitry may be electrically connected to each pair of antenna elements, with the signal to elements within a pair having a phase quadrature relationship so that the pair of antenna elements generates a scanning beam in one direction and a control pattern null is achieved in another direction. A control system controls the generation of a scanning beam output by the antenna apparatus.
