Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an indoor base station and a PIFA antenna thereof. The PIFA antenna comprises a reflection floor, a feed network and a radiation unit, wherein the radiation unit comprises a metal plate body, a feed part, open circuit branches and a short circuit branch, the metal plate body comprises a feed end and a short circuit end, and a hollow part is formed in the metal plate body.The impedance bandwidth of the PIFA antenna is relevant with the distance between the reflection floor and the metal plate body, the impedance matching is optimized by virtue of the arranged open circuit branches and short circuit branch, and furthermore, curved current is formed on the metal plate body through the current by virtue of the arranged hollow part, so that the current path is lengthened; furthermore, a loop can be formed between the short circuit end and the feed end through the short circuit branch, so that the current path can be further lengthened; and the frequencies of signals received and emitted by the radiation unit are changed along the lengthening of the current path, so that the working frequency band of the radiation unit is reduced. Therefore, the volume of the PIFA antenna can be reduced when the frequency band is extended, so that the miniaturization of the indoor base station is promoted.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an indoor base station and a PIFA antenna thereof. Background technique [0002] With the development of mobile communication networks, the demand for indoor low-power hotspot coverage is increasing rapidly, so the demand for indoor base stations with small size, low cost and good performance is also increasing. Among them, the most critical components involved in an indoor base station include a base station antenna, and currently a commonly used base station antenna for an indoor base station is a PIFA (planar inverted F-shaped) antenna. [0003] The widely used frequency band of indoor base stations is mainly 1710-2690MHz, and the frequency band is relatively wide. However, the common PIFA antenna covers a relatively narrow frequency band, so a single PIFA antenna cannot meet the requirement of covering all frequency bands of an indoor base station. Therefore, m...
