Description of the invention: [Technical field to which the invention pertains] In particular, a multi-bandwidth switching method of the present invention relates to a digital antenna structure for a digital antenna. [Prior Art] The family TV, we call it analog TV (a 'Day's signal is a continuous change, the N-bit TV is digitalized after the picture signal becomes - string number = bit tone It has been transmitted to digital boxes or digital TVs in the home to watch digital TV programs. The success of digital TVs is mainly due to the advancement of technology. The international unified compression standard is MPEG_2, which is powerful. 2 In the traditional hotline TV station 6M_ can convey 1080 horizontal scanning lines of high-definition TV (High-Definition TV) > fn m mrv — ^ — Bei electric research ^ ...% resistance. Its face than traditional TV ·:,! The surface is delicate and the color is vivid. At the same time, it also provides three-dimensional, Dolby AC3 two-level sound effects. = Under the continuous advancement of technology, many electronic products are oriented, and the work is out = small direction production' The main consideration is for the user: the digits +, f. Therefore, the digital TV is reduced to a portable type: the user can carry it or use it. In the portable digital TV颧Go #纳斯士_ Disaster link - external夭 贝 必须 must be in the digital TV casing ^ 〇 antenna, through the reception of this antenna allows users to enjoy the A car, or outdoor viewing +, 曰 & the frequency range is wider to hire 3: mesh. Because in order to let the digital The size of the digital antenna of the TV is made into a larger bar, such as the certificate number of the national patent gazette No. M27 (10) (such as the first = kg not, the fourth (four) pro number (as shown in the second figure), the first 146 Hu (such as the three brothers) and the number 443 (as shown in the fourth picture). So within 4:; = line can only take the connection between external and digital TV, extremely not portable inside the digital TV, resulting in The user is carrying [invention] Because the internal (four) out-minimum (four) digital W-type digital TV internal (four) square, the ratio is inversely proportional, the wavelength and frequency of the vibration of the gate wave can be based on the number: Second line: Γ Multiple frequency bands, when the antenna is in the frequency range, and then switch the appropriate connection. The J-body antenna can also be achieved in the broadband system operation for the above purpose, the digital receiving antenna of the present invention Improvements, including: And the:: face has a plate body, the plate body is formed with a - grounded metal surface bare;; the road::: the ground metal surface has the same side - a substrate surface line, and the:: :上:匕:ΐ: formed on the metal-microstrip one day _ has a number of wires and contacts on the curve.

Electrical connection, and the first, second, 14, 15 other - The terminals are electrically connected to the antenna unit 2, and the spring m forms an antenna capable of switching multiple frequency bands, and the external frequency modulation device is arranged in the switch unit (figure The signals are not driven. The signal is driven by the frequency converter ,% to switch the frequency band of the antenna unit 2. The estimation M only allows the digital TV with the same type to receive digital signals of different frequency bands to watch digital TV programs. The image of the digital antenna structure of the present invention and the internal circuit of the switch 7L are shown in Fig. As shown in the figure, the substrate 1 disclosed in the figure has a plate body 10, and the plate body 10 is formed with a grounding metal surface 11 and a first exposed surface 16 on the same side of the grounded metal surface n. a second exposed surface 17 which exposes the surface of the substrate 1 and which is formed with a metal microstrip line 12, and the end of the metal microstrip line 12 extends to the bottom end of the second exposed surface 17 There is a contact 121, which can be electrically connected to the wire or coaxial wire lead to form a __ signal feed point, so that the signal can be transmitted to the circuit board (not shown) of the mobile device. The metal micro, the other end of the line 12 is electrically connected to the wheel end 35 of the switch unit 3, and the input end 33 of the switch unit 3 and the first and second on the first exposed surface 16 respectively: = line 1_3, 14, The contacts (3), 141, and (5) of 15 are electrically connected; and the other ends of the two wires 13, 14, 15 each have a contact = 142, 152 ' and the first exposed surface 16 has a contact with the contact 152. Another junction adjacent to 161. The antenna unit 2 is a carrier 21 having a high dielectric constant material (κ^4), and the two ends of the carrier 21 are covered with a first _ '=electrode 23, and the second electrode 22 When the continuous conductor 24 70 2 which is electrically connected to the surface of the carrier 21 is electrically connected to the substrate 1, the first, 22, i3 and the contact 132 of the antenna unit are de-energized.

Ρ has a plurality of ground terminals 31, three control terminals 32, three input terminals /, when the frequency of the channel of the switching frequency converter 4 is in the range of 550~650MHZ, the guard frequency is 4 rounds. The signal is input by the second control pin 322, and the control pin 322 is hlgh, so that the second switch 342 is turned on. The digital signal received by the early 7L 2 will be output by the second wire 14 (because of the antenna block used for the volts) Where the length of 2 is shortened, the wavelength is inversely proportional to the frequency. Therefore, the frequency #增力0' is transmitted through the second micro-strip line 12 to the digital television via the second input pin 332 and the second switch power. The opposite is the process of 't'. At this time, the system can receive the digital slogan within the bandwidth. When 兮f: the frequency of the channel with a frequency of 4 is in the range of 650~·Hz. The signal outputted by 4 is input by the third control pin 323, day:: single: = Γ23 is _, the third switch 343 is turned on, and the used day: the bit signal will be output by the third wire 15 (because 俜, The length of the early 兀 2 is shortened, because the wavelength is inversely proportional to the frequency. 343 ^ " The foot 333 and the third switch circuit board are processed, at this time: the second is transmitted to the television signal of the digital television. The human P can receive the digits in the range of the έ 频 bandwidth, which is shown in the figure of the other embodiment of the present invention.
