Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method and device for manufacturing a multi-working frequency antenna, in particular, a metal spirally wound on the surface of a ceramic substrate with a high dielectric constant. Working frequency antenna. [Prior art] The antenna is designed to radiate or receive electromagnetic waves in transmission and reception systems. Sting, 疋 is a transducer of electricity and waves, which is converted into wave radiation. Flooding of the Global Positioning System (GPS). It also has the requirements for its antenna to provide right-hand circular polarization and its field shape can uniformly cover the entire upper hemisphere; the circular polarization operation design is used in satellite communication propagation The propagation method has no restrictions on the transmission of electrical property in the direction of transmission and reception, and is far from linear polarization. In addition, the electromagnetic wave in the ionosphere will produce a normal rotation effect, which makes circular polarization extremely important in satellite communications. Sex. When the helical antenna works in the axial mode, fortunately, the situation of 5 shots is the same as that of an end-fire antenna (end-fire), and it is shot lightly along the axis of the helical antenna itself; Axial mode occurs when the circumference of the antenna is about one wavelength. In addition, the health and wireless mobile communications market is booming rapidly, and the development of communication systems with wireless satellite communications technology and highly mobile communications equipment 1238566 4 /,-most of this development is due to the miniaturization and lightweight of key components. Some of the functions of the mr may have the function of an axis metal resonator, and this type is called a dielectric resonator (dieleetric resound, such as DR). In the current trend of pursuing products to be light, thin, short, and small, μ-wave dielectrics with high dielectric values play an important role. For dielectric materials, the size of the dielectric material affects the size of the component and the size of the recording. It mainly depends on its ability to be polarized. Read the picture in Figure A. 'It is a conventional normal mode helical antenna. The figure shows that when the antenna is working in the normal mode, the vertical direction of the radiating field is the largest. The axis of the antenna; since the diameter of the antenna under this test will be much smaller than one wavelength, and the spiral helix will be relatively small !! The circumference G1 will be much smaller than-long, so the spiral state of the Falai state =, the nature is small, so , Its efficiency is also very low, the degree of circular polarization is not ideal. Please refer to Figure -B, which shows the conventional axial modal spiral antenna: Figure. ^ It can be seen from the figure that when the helical antenna works in a purely directional mode (Axiai 〇e Rishou), its radiation field has an endfire effect, and it is emitted along the sister of the helical antenna itself; this mode occurs all in the antenna. When the circumference c2 is about one wavelength. In this way, the directional helical antenna of the car can provide stable identification and circular polarization of high magic na, so it is widely used in satellite communications. The secret four metal wires are shown in the figure: 'The single-loop four metal wires are composed of metal wires with a phase difference of about X ~ D. In conventional technology, such as US Patent No. 1238566 US6300917 [Antenna (ΑΝΤΕΝΑ)], US Patent Case No. jjs6552693 [ANTENA], US Patent No. US6424316 [HELICAL ANTENA], it can be clearly seen that the degree of circular polarization of the conventional invention is difficult to control in design. However, the antenna design is generally known. It has the following disadvantages: 1. The single-loop four-metal wire spirally wound on the ceramic substrate of the antenna, which causes the fixation between the metal wires, making it difficult to adjust the circular polarization field type of the antenna; 2. The single-circuit four-metal wire wound around the ceramic ceramic substrate of the antenna forms a small working bandwidth for receiving signals. Based on the above, it is known that the above-mentioned conventional manufacturing method and device for multiple working frequency antennas are practical. In terms of design and system, there are inconveniences and shortcomings that need to be improved. ^ Yes, the above-mentioned shortcomings of the Wei people can be improved, and based on years of relevant experience in this field, carefully observe and study, and match: ==, and propose a reasonable design and effectively improve the conventional multiplexing; the present invention of a method and device for the lack of frequency antenna clothing.
