    • A sparse array antenna is disclosed. The antenna comprises series-fed antenna array columns tuned to a respective transmit and receive frequency. The transmitting and receiving radiation elements are formed with a given distance between each transmitting radiator element and each receiving radiator element, and the series-fed antenna columns are arranged in parallel, perpendicular to a symmetry line forming a symmetric interleaved transmit/receive array. Furthermore the receiving array columns operate as parasitic elements in a transmit mode and transmitting array columns operate as a parasitic elements in a receive mode, thereby reducing creation of grating lobes. The created sparse array antenna may further be arranged to be scanable to also provide reduced sidelobes entering visual space when scanning the main radiation lobe from an off boresight direction. Typically the series-fed array columns may be formed as extended ridged slotted wave-guides tuned to a respective transmitting or receiving frequency.
    • 公开了一种稀疏阵列天线。 该天线包括被调谐到相应发射和接收频率的串联馈送天线阵列列。 发射和接收辐射元件在每个发射辐射体元件和每个接收辐射体元件之间以给定的距离形成,并且串联馈送的天线列与垂直于形成对称交错的发射/接收阵列的对称线平行布置。 此外,接收阵列列以发射模式作为寄生元件运行,并且发射阵列列作为接收模式中的寄生元件运行,从而减少了栅瓣的产生。 所创建的稀疏阵列天线可进一步被布置成可扫描,以便在从远视线方向扫描主辐射波瓣时还提供进入视觉空间的减少的旁瓣。 通常,串联馈送的阵列列可以形成为被调谐到相应的发射或接收频率的延伸的有脊的时隙波导。
