    摘要： New type of planar antenna of microwaves appropriate for operating in linear or circular polarization, free of welds and floating potentials, and therefore free of electrostatic discharges and problems related to passive intermodulation products, whose application is of particular interest in aircraft and space technologies. Said antenna consists in the interconnection of a microstrip radiator with a spiral antenna of wires. For certain applications wherein said radiators are arranged in a same plane, the radiating effect of the patch may reduce the size of the spiral, whereby the radiator object of this invention degenerates into a circular slit in the ground plane of the supply line and wherein the helically arranged wires provide for the electric contact between the edges of the slit.

    摘要翻译： 新型的微波平面天线适用于线性或圆形极化，无焊缝和浮动电位，因此无静电放电和与被动互调产品相关的问题，其应用在飞机和空间技术中尤为重要。 所述天线包括微带散热器与电线螺旋天线的互连。 对于其中所述辐射器布置在同一平面中的某些应用，贴片的辐射效应可以减小螺旋的尺寸，由此本发明的散热器物体退化为供电线的接地平面中的圆形狭缝，并且其中 螺旋布置的导线提供狭缝边缘之间的电接触。
