    • A dual, preferably orthogonally polarized microstrip patch antenna which includes a layer of electrically insulating material in the form of a printed circuit board. First and second sets of electrically conductive patches, preferably of copper, are disposed on one surface of the electrically insulating material, the first set adapted for transmission and/or reception of electromagnetic radiations polarized in a first direction and the second set adapted for transmission and/or reception of electromagnetic radiations polarized in a second direction. Patches of the first set are interlaced with patches of the second set. A feed for each of the patches is coupled to the opposing surface of the electrically insulating material which includes a first plurality of slots, one associated with each of the patches of the first set for polarizing the patches of the first set in the first direction and a second plurality of slots, one associated with each of the patches of the second set for polarizing the patches of the second set in the second direction. The centers of the patches of the first and second sets of patches are disposed in a straight line and the centers of adjacent patches of each of the sets of patches are spaced apart less than one wavelength of the carrier frequency of interest.
    • 双重优选正交极化的微带贴片天线,其包括印刷电路板形式的电绝缘材料层。 第一组和第二组导电贴片,优选为铜布置在电绝缘材料的一个表面上,第一组适于传输和/或接收在第一方向上极化的电磁辐射,第二组适于传输和/ /或接收在第二方向上极化的电磁辐射。 第一组的贴片与第二组的贴片交错。 用于每个贴片的馈电耦合到电绝缘材料的相对表面,该电绝缘材料包括第一多个狭槽,一个与第一组中的每个贴片相关联,用于使第一组的贴片沿第一方向偏振, 第二多个槽,一个与第二组的每个补片相关联,用于在第二方向上偏振第二组的补片。 第一组和第二组贴片的贴片的中心以直线布置,并且每组贴片的相邻贴片的中心间隔开小于感兴趣的载波频率的一个波长。
