摘要:
The hybrid antenna includes a spiral antenna, e.g. a log spiral antenna, and a patch array layer adjacent to the spiral antenna and including a passive periodic patch array of conductive patch elements. A conductive ground plane may be adjacent to the patch array layer, and a dielectric layer may be between the conductive ground plane and the patch array. The spiral antenna may include an upper antenna arm, a lower antenna arm and a dielectric sheet therebetween. Each of the upper and lower antenna arms may be a printed planar conductive trace that is wider at a distal end thereof with respect to a center of the log spiral antenna. The patch or periodic array layer operates in conjunction with the ground plane to couple energy into the spiral antenna and thereby improve low frequency antenna efficiency while maintaining electrically small dimensions.
摘要(中):
混合天线包括螺旋天线,例如。 对数螺旋天线和邻近螺旋天线的贴片阵列层,并且包括导电贴片元件的无源周期性贴片阵列。 导电接地平面可以与贴片阵列层相邻,并且电介质层可以在导电接地平面和贴片阵列之间。 螺旋天线可以包括上天线臂,下天线臂和它们之间的介电片。 上天线臂和下天线臂中的每一个可以是相对于对数螺旋天线的中心在其远端处更宽的印刷平面导电迹线。 贴片或周期性阵列层与地平面结合操作以将能量耦合到螺旋天线中,从而在保持电小尺寸的同时提高低频天线效率。
