Circularly polarized wave patch antenna with wide shortcircuit portion |
摘要 |
A patch and a ground conductor are shortcircuited with two shortcircuit portions that are composed of conductive plates and that pass through a dielectric substrate. The shortcircuit portions are connected to the inner periphery of the patch and have large widths therealong. A first shortcircuit portion is disposed on a first line that connects a microstrip feeder line and the center point of the patch. A second shortcircuit portion is disposed on a second line that passes through the center point. The inner angle of the first line and the second line is in the range from 80 degrees to 110 degrees.
