[0004] However, the length of the antenna body of the inverted-F antenna needs to be substantially equal to a quarter of the wavelength of the radio signal to be transmitted and received by the antenna. For the increasingly shrinking circuit modules, this restriction on the length of the antenna body is the cause of the overall The main factors that make it difficult to further reduce the size of the module

Embodiment Construction
[0031] Embodiments of the present invention will be described below in conjunction with related drawings. In the drawings, the same reference numerals designate the same or similar elements.
[0032] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art should understand that the same element may be called by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. "Includes" mentioned throughout the specification and claims is an open-ended term, so it should be interpreted as "including but not limited to...".
[0033] Please refer to figure 1 , which is a simplified schematic diagram of a planar inverted-F antenna (Planar Inverted-F Antenna, PIFA) 10 according to an embodiment of the present invention. The antenna 10 includes a radiating body, a short-circuit pin 110 ext...

The invention discloses an inverted-F antenna (IFA) and a correlated radio communication apparatus. According to an IFA embodiment provided in the technical scheme, the IFA comprises: a radiation main body, wherein the radiation main body comprises a plurality of radiation portions and part of radiation portions among the plurality of radiation portions are at a same plane; a short circuit pin, wherein the short circuit pin is extended outwardly from the radiation main body and a first predetermined included angle is formed between one of the plurality of radiation portions and the short circuit pin; a feed-in pin, wherein the feed-in pin is extended outwardly from the radiation main body and a second predetermined included angle is formed between one of the plurality of radiation portions and the feed-in pin; and a protrusion portion, wherein the protrusion portion is extended outwardly from one of the plurality of radiation portions and a third predetermined included angle is formed between one of the plurality of radiation portions and at least a local portion of the protrusion portion. Besides, at least one among the first predetermined included angle, the second predetermined included angle and the third predetermined included angle is a right angle virtually.
Description
technical field [0001] The invention relates to an antenna, in particular to an inverted-F antenna used in wireless communication equipment. Background technique [0002] Antenna is one of the important components in wireless communication equipment, but it is also one of the components with the largest area and size in circuit modules. As wireless communication-related products tend to emphasize lightness, thinness, shortness, and smallness, the miniaturization of antennas has become the mainstream of today's design. [0003] In the related technical field, an inverted-F antenna (Inverted-F Antenna, IFA) is a type of antenna that is often used, mainly because it has the advantage of an approximately omnidirectional radiation pattern, so it is widely used in network cards. , mobile phones and other portable wireless electronic devices. [0004] However, the length of the main body of the inverted-F antenna needs to be substantially equal to a quarter of the wavelength of t...
