摘要： A patch antenna (10) includes a dielectric substrate (12), a patch conductor (14) and a ground conductor (18) formed on both surfaces thereof. A step (16) is formed on the lower surface of the dielectric substrate, which makes a spacing between the patch conductor and the ground conductor nonuniform in a direction of length of the patch conductor. By making nonuniform the spacing between the patch conductor and the ground conductor in the direction of length of the patch conductor, radiation efficiency and antenna gain are changed in that direction, resulting in asymmetrical directivity.

摘要： In the present invention, a patch antenna wherein electric waves in two frequency bands can be transmitted and received is provided with smaller dimensions and a lower cost than in the conventional arts. The patch antenna has a radiation electrode and a ground conductor disposed to oppose each other, and has dielectrics in the gap between the radiation electrode and the ground conductor. The radiation electrode and the ground conductor are made of a material being excellent in electric conductivity. The radiation electrode is rectangular in a plan view. A power supplying part is disposed at a position having substantially the same distance from the opposing two sides of the radiation electrode. The thickness of the dielectrics differs with a boundary located at the position of distance a from one terminal side of the radiation electrode in the longer-side direction of the radiation electrode.
摘要翻译：在本发明中，与现有技术相比，能够发送接收两个频带的电波的贴片天线具有较小的尺寸和较低的成本。贴片天线具有彼此相对设置的放射电极和接地导体，并且在辐射电极和接地导体之间的间隙中具有电介质。辐射电极和接地导体由导电性优异的材料制成。辐射电极在平面图中是矩形的。供电部设置在与放射电极的相对的两侧具有大致相同距离的位置。电介质的厚度与放射电极的长边方向的距辐射电极的一个端子侧的距离a的位置的边界不同。
