Embodiment Construction

[0015] figure 2 and image 3 Shown is the antenna assembly 100 of the preferred embodiment of the present invention, which can be applied to portable electronic devices with navigation functions such as GPS. The antenna assembly 100 includes a circuit substrate 120 and two antennas 140 that are axially symmetrically arranged on the same side of the circuit substrate 120.

[0016] In this embodiment, the circuit substrate 120 may be a circular, rectangular, or other axisymmetric printed circuit board (Printed Circuit Board, PCB). The circuit substrate 120 is provided with two grounding points 122 axisymmetrically. A feed point 124 is provided adjacent to each ground point 122 respectively. The feed points 124 are distributed axially symmetrically and share a symmetry axis with the ground point 122.

[0017] The antennas 140 are Planar Inverted-F Antennas (PIFA), and each antenna 140 includes a radiating element 142, a feeding end 144 and a grounding end 146. The radiating element...

Abstract

The invention provides an antenna component, comprising a circuit board, two antennas are arranged on the circuit board in an axisymmetric way, and the antenna is a plane reverse F-shaped antenna.

Description

Technical field [0001] The present invention relates to an antenna assembly, in particular to an antenna assembly with a circularly polarized wave radiation effect. Background technique [0002] At present, many portable electronic devices such as mobile phones and personal digital assistants (Personal Digital Assistants, PDAs) are equipped with global positioning system (GPS) or navigation functions. For example, when using the GPS function, circular polarization is generally required. An antenna can effectively receive satellite signals. [0003] In order to enable the antenna to have the radiation effect of circular polarized waves, the conventional patch antenna (Patch Antenna) is the mainstream design in the prior art. See figure 1 A known patch antenna 1 that can be used in a GPS system includes a short-circuit point 11, a feeding point 12, and a radiation patch 13, wherein a cross-shaped slot 14 is provided in the center of the radiation patch 13. In this patch antenna, th...
