[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0024] figure 1 It is a structural schematic diagram of the multi-frequency circularly polarized antenna of the present invention. like figure 1 As shown, a kind of multi-frequency circularly polarized antenna provided by the present invention includes: a rectangular dielectric plate 10 and an antenna piece 20, and the antenna piece 20 is arranged along one side of the rectangular dielectric plate 10 from the end corner of the rectangular dielectric plate 10 , the antenna piece 20 is perpendicular to the rectangular dielectric plate 10 . The shape and size of the rectangular dielectric plate 10 are the same as the device to which the antenna is applied. For example, if the antenna of the present invention is used in the navigation and positioning of a...
