Problems solved by technology

However, under the premise that TV screens tend to be smaller and thinner, if the wireless module wants to use a planar inverted-F antenna to receive WLAN dual-band signals, it often cannot meet the requirements of thin size and large bandwidth at the same time.

Embodiment Construction

[0030] The present invention relates to a broadband planar inverted-F antenna with dual frequency bands. A radiating arm and a recessed structure are formed in the planar radiation conductor to generate resonant standing wave radiation and traveling wave radiation when signals are fed in, and the recessed structure The distance between the opposite sides gradually becomes larger from the opening of the concave structure along the direction of the closed bottom of the concave structure, so as to increase the signal bandwidth of the traveling wave radiation. Therefore, a planar inverted-F antenna with both thinness and large bandwidth can be produced, which is suitable for being built into a thin and thin frame of a TV screen, and at the same time meets the requirement of large bandwidth required for WLAN communication.

[0031] Please refer to Figure 1A , which shows a structure diagram of a broadband planar inverted-F antenna according to a preferred embodiment of the present ...

Abstract

A broadband planar inverted-F antenna includes a first radiation conductor, a second radiation conductor and a third radiation conductor. The first radiation conductor includes a first inclined-plane portion and a feeding point. The feeding point is located at one end of the first inclined-plane portion. The second radiation conductor is connected to the first radiation conductor at the feeding point. The third radiation conductor is connected to the first radiation conductor, and includes a second inclined-plane portion and a ground point. The second inclined-plane portion is separated from and facing to the first inclined-plane portion. The ground point is located at one end of the second inclined-plane portion and facing to the feeding point, wherein the distance between the first inclined-plane portion and the second inclined-plane portion is gradually increased from the part near the feeding point along a direction departing from the feeding point.

Description

technical field [0001] The present invention relates to a broadband planar inverted-F antenna (Planar Inverted-F Antenna; PIFA), and in particular to a dual-band and broadband planar inverted-F antenna built in a thin frame TV. Background technique [0002] With the vigorous development of wireless communication, many communication products tend to be miniaturized. Therefore, the antenna requires a small volume and an embedded structure to meet the aesthetics. Compared with the monopole antenna and the inverted F antenna, the planar inverted F antenna has the characteristics of small size and large bandwidth, and can receive dual-band and multi-band wireless signals through the appropriate design of the radiation conductor, so it has been widely used Applied to signal reception of wireless electronic products such as mobile phones. [0003] In addition, in recent years, the digital television (DTV) has been combined with a wireless module to receive wireless signals of the ...
