    • A wideband slot-loop antenna is described which comprises a generally planar loop element having a generally rectangular outer perimeter and a slot defining an inner perimeter, the mid portion of the slot-loop structure providing a major radiation portion of the antenna; a loading structure extending from one end of the slot, the loading structure for top loading the radiation portion; and an impedance matching portion for coupling a feed to the major radiation portion. The antenna also includes distributed matching patches. The distributed matching patches realize extra wideband performance. The antennas in the present invention are suitable for various wireless communications, such as PCS, Cellular Telephone, wireless data and computer network.
    • 描述了一种宽带槽环天线,其包括具有大致矩形的外周边和限定内周的槽的大致平面的环形元件,所述槽环结构的中间部分提供天线的主辐射部分; 从槽的一端延伸的装载结构,用于顶部装载辐射部分的装载结构; 以及用于将馈送耦合到主辐射部分的阻抗匹配部分。 天线还包括分布式匹配补丁。 分布式匹配补丁实现了额外的宽带性能。 本发明中的天线适用于各种无线通信,例如PCS,蜂窝电话,无线数据和计算机网络。
