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 present invention relates to an indoor base station and a PIFA antenna thereof. The PIFA antenna comprises a reflection floor, a feed network and a radiating element. The radiating element comprises a metal plate body, a feed part, an open-circuit branch and a short-circuit branch, wherein the metal plate body is provided with a feed end and a short-circuit end, and a hollow portion is formed on the metal plate body. The impedance bandwidth of the PIFA antenna is related to the distance between the reflection floor and the metal plate body, and the configurations of the open-circuit branch and the short-circuit branch are conducive to optimizing impedance matching; furthermore, the configuration of the hollow portion enables an electric current to form a meander on the metal plate body, so that a current path is elongated. Moreover, the short-circuit branch can form a loop between the short-circuit end and a feed end, so as to further extend a current path. Since the current path is extended, the signal frequency that the radiating element can receive and send also changes therewith, so that the working frequency band of the radiating element is reduced. It can be seen that the coverage frequency band of the PIFA antenna can be expanded while the volume thereof is reduced, and this is beneficial to the miniaturization of an indoor base station.

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...
