圆极化天线及电子设备
摘要：
本发明公开了一种圆极化天线及电子设备。该圆极化天线包括偶极子天线阵列和馈电网络。在该天线阵列中，每个偶极子天线的第一和第二分支是辐射分支，第三和第四分支是馈电分支；所述馈电网络包括第一和第二馈电分支，用于提供具有90°相位差的馈电信号，其中，第一偶极子天线的第三分支与第一馈电分支相连，第二偶极子天线的第三分支与第二馈电分支相连，其他天线分支接地。与现有技术相比，根据本发明的圆极化天线的馈电网络结构简单。
摘要（英）：

The invention discloses a circularly-polarized antenna and electronic equipment. The circularly-polarized antenna comprises a dipole antenna array and a feed network. In the antenna array, first and second branches of each dipole antenna are radiation branches, and third and fourth branches are feed branches. The feed network comprises first and second feed branches used for providing a feed signal possessing a 90 degree phase difference. The third branch of a first dipole antenna is connected to the first feed branch, and the third branch of a second dipole antenna is connected to the second feed branch. Other antenna branches are grounded. Compared to the prior art, the structure of the feed network of the circularly-polarized antenna in the invention is simple.
