 技術摘要 / Our Technology： |
一種槽孔天線，用以傳輸一圓極化訊號，包括一天線基板、一饋入導體以及一天線接地層。天線基板具有一第一表面以及一第二表面。饋入導體設於該第一表面。天線接地層設於該第二表面，其中，該天線接地層具有一槽孔，該槽孔具有一饋入點、一訊號折點、一第一邊緣以及一第二邊緣，該第一邊緣沿一第一方向連接該饋入點以及該訊號折點，該第二邊緣沿一第二方向連接該饋入點以及該訊號折點，該第一方向相反於該第二方向，當該槽孔天線傳輸該圓極化訊號時，一行進波(traveling wave)於該第一邊緣上行進，至少一駐波於該第二邊緣上震盪。
An aperture antenna for transmitting a circularly polarized signal is provided. The aperture antenna includes an antenna substrate, a feed conductor and an antenna ground layer. The feed conductor is microstrip-fed or coplanar-wave-guide-fed. The antenna ground layer has an aperture, the aperture has a feed portion, a signal turning point, a first edge and a second edge, the first edge connects the feed portion to the signal turning point in a first direction, and the second edge connects the feed portion to the signal turning point in a second direction, the first direction is opposite to the second direction. When the aperture antenna transmits the circularly polarized signal, a traveling wave travels on the first edge, and at least one standing wave is formed on the second edge.
