Problems solved by technology

Since the antennas have a certain length and volume, they not only need to occupy installation space, but are also easily damaged due to external force collisions, and additional assembly procedures and costs need to be added. Therefore, how to further reduce and see through the antennas Or invisible, in order to save the occupied space, and let it be arranged on the picture frame glass, photo frame glass or car windshield for receiving radio signals without destroying the beauty and visual effect, it becomes An important issue that every antenna industry wants to solve

Embodiment Construction

[0041] The present invention is a fractal antenna. As shown in FIG. 1, the fractal antenna 10 includes two symmetrically arranged antenna components 201, 202, and the two antenna components 201, 202 are arranged on a side surface 111 of a dielectric material 11. Above, to form a double dipole (dipole) antenna, each of the antenna components 201, 202 is formed by repeated evolution (iteration) of a metal microstrip 21 according to a fractal algorithm (fractal algorithm), and the two metal microstrips The adjacent ends of the dielectric material 11 are respectively connected with a matching network 214 for modification to achieve the best matching state, and a certain gap T is reserved therebetween. On the other side 112 of the dielectric material 11, corresponding to the An antenna assembly 201 and the position of the gap T are provided with a metal sheet 40 for coupling. After the central core wire 31 of the coaxial cable 30 passes through the dielectric material 11 from the po...

Abstract

Being setup on side face of a dielectric material, fractal type antenna composed of two symmetrical arranged antenna modules forms a dipole antenna. Each antenna module is produced by iteration based on fractal algorithm for prearranged shaped metal microstrip. A matching network is respectively connected to one end of adjacent metal microstrips. There is a gap between matching networks. Being setup on the other side face of the dielectric material, a metal piece is corresponding to an antenna module and a gap. Passing through the dielectric material, central core wire of coaxial cable is connected to the metal piece in use for coupling. Shielding wire of the coaxial cable is connected to a matching network of another antenna module. Capacitance coupling type Balun interface is formed between the antenna and the coaxial cable. Thus, electric wave signal received by antenna can be transferred to the coaxial cable successfully.

Description

technical field [0001] The present invention relates to an antenna for receiving digital TV program signals, especially an antenna that uses a basic and simple metal microstrip to evolve a fractal shape repeatedly by itself, so as to reduce the size of the antenna and make it With the advantages of broadband or multi-frequency, the fractal antenna can be placed on a picture frame, photo frame or car windshield for receiving radio signals without damaging the appearance or affecting the visual effect. Background technique [0002] At present, the digital TV system is a new wireless TV technology. Its working principle converts the "analog signal" used in current TV programs into a "digital signal" and broadcasts it through multitasking, modulation and other processing technologies. , the text or image information of digital TV programs played by digital TV is composed of digital signals such as 0 and 1, so that when users watch digital TV programs, they can access or store ac...
