Embodiment 1

[0056] Such as Figure 1~3 As shown, this embodiment shows a miniature patch antenna, which includes an FR4 dielectric substrate 100, a folded line radiation patch 200 located on the front side of the FR4 dielectric substrate 100, an edge front loading unit 400 and a feeder 300, and The edge backside loading unit 600 located on the backside of the FR4 dielectric substrate 100, the size of the miniature patch antenna is designed to be 5mm*5mm, which is printed at the relative permittivity ε r =4.4, loss tangent tanδ =0.02 on the FR4 dielectric substrate 100, the size of the FR4 dielectric substrate 100 is 20mm*20mm*1mm, that is, the micro-patch antenna is formed on the 5mm*5mm spacer 110 separated by the FR4 dielectric substrate 100, The outside of the spacer 110 is the ground plane of the dielectric substrate 100. It can be understood that when the antenna is formed by a printing process, the spacer 110 is a blank area before the miniature patch antenna is formed, that is, ...

Abstract

The invention discloses a miniature patch antenna which comprises the components of a broken line type radiation patch which is arranged on the front surface of a dielectric substrate, and an edge front loading unit and an edge back loading unit, wherein one end of the broken line type radiation patch is connected with a feeding part; the edge front loading unit and the edge back loading unit arecorrespondingly arranged and are respectively positioned on the front surface and the back surface of the dielectric substrate, and a spacing groove is formed between the edge front loading unit and the broken line type radiation patch. According to the invention, the broken line type radiation patch, i.e., a non-existing planar radiation patch, is adopted, and the perimeter of the broken line type radiation patch can be increased without changing the area of the patch, so that the current flowing path is increased, and the miniaturization design is realized; the edge front surface loading patches and the edge back surface loading patches on the front and back surfaces improve the current distribution in the antenna, and can reduce the resonant frequency of the antenna or reduce the size of the antenna under the same working frequency, thereby further realizing the miniaturization of the antenna, and ensuring the stable working frequency band of the miniature patch antenna at the sametime.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a miniature patch antenna. Background technique [0002] WLAN is the abbreviation of Wireless Local Area Network (wireless local area network). It is a technology combining wireless communication and computer network. It is a solution for wireless data transmission and can realize user mobility. Due to its low price, flexible networking form, and support for high-speed data access, WLAN has been applied in industries such as medical care, manufacturing, and retail. [0003] With the proposal of the IEEE802.11b / g (2.4-2.4835GHz) standard and technological progress including antennas, the wireless LAN communication technology has developed rapidly, which can achieve the coverage of the entire area while taking into account the signal strength of each point . At the same time, the demand for WLAN antennas is gradually increasing. Whether it is a mobile phone, a wireless network c...
