Problems solved by technology

On the other hand, existing GPRS antenna basically adopts spiral metal antenna, its cost is higher, and it is also inconvenient to combine with existing electronic equipment (such as satellite TV set-top box, etc.), so it is necessary to provide a GPRS antenna that is convenient to combine with existing electronic equipment. Antenna is a technical problem faced by antenna design industry

Embodiment approach

[0044] In order to reduce the energy loss of the antenna and improve the performance of the entire GPRS antenna, a low-dielectric constant and low-loss dielectric substrate is used as the dielectric substrate of the GPRS antenna 15. The dielectric substrate 4 has a nominal dielectric value of ≤4.0 at a working frequency of 1GHz Constant and electrical loss tangent of ≤0.0002. The dielectric substrate 4 includes glass fiber cloth, epoxy resin and a compound that reacts cross-linked with the epoxy resin. The first type of implementation of the dielectric substrate is as follows:

[0045] The manufacturing process of the dielectric substrate 4 is as follows: first, a wetting solution is provided including: a first component, which contains epoxy resin; a second component, which contains a compound that cross-links with the epoxy resin; and a or various solvents. Wherein the first component and the second component are configured and mixed according to a certain ratio.

[0069] Please also refer to Figure 6 , 7 and 8 are schematic diagrams of the fourth embodiment of the GPRS antenna. The GPRS antenna includes a dielectric substrate 1 and an antenna unit 3 arranged on both surfaces of the dielectric substrate 1, the dielectric substrate 1 includes a first surface 5 and a second surface 6 opposite to the first surface 5 . The antenna unit 3 includes a first resonant frequency band unit EFGHJ and a second resonant frequency band unit EC; the first resonant frequency band unit EFGHJ and the second resonant frequency band unit EI are coupled to each other and share a feeder E. In this embodiment, the first resonant frequency band unit EFHGJ and a second resonant frequency band unit EI are both disposed on the first surface 5 of the dielectric substrate 1 . In other embodiments, the first resonant frequency band unit EFHGJ and a second resonant frequency band unit EI are respectively disposed on the first surface 5 and the second surface 6 of t...

Abstract

A GPRS electronic device includes a GPRS antenna, and the GPRS antenna includes: a dielectric substrate including a first surface and a second surface opposite to the first surface; an antenna unit including a first resonant frequency band The unit and a second resonant frequency band unit are arranged on the surface of the dielectric substrate; the first resonant frequency band unit and the second resonant frequency band unit share a feeder and are coupled to each other. Compared with the existing spiral technology GPRS antenna, the low-cost planar GPRS antenna is adopted, which is a GPRS antenna that is conveniently combined with electronic equipment.

Description

technical field [0001] The present invention relates to a wireless communication device, more specifically, to a GPRS electronic device. Background technique [0002] General Packet Radio Service (GPRS for short) is a packet data bearer service. Because GPRS communication is not limited by the working distance, it is especially suitable for complex areas such as urban areas and mountainous areas where electrical signals are blocked seriously and has been widely used. GPRS communication working frequency range is 880~960MHz and 1710~1880MHz. [0003] The existing GPRS antenna basically adopts a rod antenna, so the length of the antenna is relatively long when it is in use, and it is not suitable for use as an antenna component of a consumer electronic product. In the field of radio frequency antenna technology, antennas designed based on copper-clad laminates have the advantages of being plate-shaped, which also makes them widely used in various electronic devices. After re...
