Problems solved by technology

[0002] As far as the current general GPS antenna design is concerned, because GPS satellite signals are transmitted by right-handed circularly polarized waves, traditional GPS circularly polarized receiving antennas are mostly designed as planar antennas. The advantages of this type of antenna are It has circular polarization characteristics and high directivity, but based on the current design of existing antenna products on the market, it needs to occupy at least a whole piece of about 12 x 12 mm 2 The rectangula

Example Embodiment

[0018] See figure 1 versus figure 2 The first embodiment of the present invention provides a dual-path inverted-F antenna structure 15 with circular polarization characteristics, which is applied to a portable electronic device 1. The portable electronic device 1 can be a mobile phone, a tablet computer, a watch, or the like. The portable electronic device 1 further includes a circuit board 11, a display screen 12, a circuit shield 13 and a casing 14.

[0019] In this embodiment, the casing 14 is a rectangular frame, which defines an accommodating space 142 for accommodating the circuit board 11, the display screen 12, the circuit shield 13 and the dual-path inverted F antenna structure 15 therein Inside, and then load and protect all the components.

[0020] The circuit board 11 has a square structure and is fixed to the bottom end of the casing 14. On both sides of the circuit board 11 close to one corner thereof, an antenna clearance area 111 is respectively provided to impro...

Abstract

An antenna structure includes a first radiation arm, a second radiation arm, a feed end, and a ground end. The second radiation arm is perpendicularly connected to the first radiation arm. The first radiation arm and the second radiation arm jointly form a junction, both the feed end and the ground end are positioned adjacent to the junction.

Description

technical field [0001] The invention relates to an antenna structure, in particular to an inverted F-shaped antenna structure and a portable electronic device with the antenna structure. Background technique [0002] As far as the current general GPS antenna design is concerned, because GPS satellite signals are transmitted by right-handed circularly polarized waves, traditional GPS circularly polarized receiving antennas are mostly designed as planar antennas. The advantages of this type of antenna are It has circular polarization characteristics and high directivity, but based on the current design of existing antenna products on the market, it needs to occupy at least a whole piece of about 12 x 12 mm 2 The rectangular design area is not conducive to the spatial arrangement of existing mobile communication devices, especially small-sized devices such as smart watches. Therefore, the general design is mainly based on the linearly polarized inverted F-shaped antenna design,...
