Abstract
A circularly polarized antenna has a dielectric substrate, a feeding member, a coupling member, a ground plane, a support and a radiating patch. The feeding member is mounted on the dielectric substrate and has a first conductor, a second conductor, a connecting conductor and a third conductor. The second conductor is connected to the first conductor. The connecting conductor is connected to the first conductor. The third conductor is connected to the connecting conductor and is parallel to the second conductor. The coupling member is connected to the feeding member. The ground plane is mounted on the dielectric substrate. The support is mounted on the dielectric substrate. The radiating member is mounted on the support. The circularly polarized antenna generates the circularly polarized radiation being parallel to the ground plane so that portable wireless products with the circularly polarized antenna have an excellent gain.
