Description

The structure of the big frequency range antenna of tool

Technical field

The utility model relates to the structure of the big frequency range antenna of a kind of tool, uses a copper pipe as antenna body frame structure, and the frequency response of required frequency band is provided, and especially partly replaces the antenna of traditional helical coil framework at low frequency.

Background technology

The application of antenna is very extensive, such as need to use the product of wireless telecommunications, the existence of antenna is nearly all arranged, and antenna concerns that wireless signal receives and launch mass very corrupt, therefore it is constructed a little difference and can cause antenna receiving-sending news quality, see also TaiWan, China patent announcement number M290618 number " miniaturization digital broadcasting antenna " novel patent, it is to interconnect by first antenna and second antenna, to reach the purpose that it shortens antenna length, but described first antenna and second antenna are all helicoidal structure, and described helicoidal structure antenna has following shortcoming:

Helical antenna received signal instability: because helical antenna may cause elastic fatigue because service time is longer, length is increase and decrease to some extent naturally, and different antennae frequency response that length causes is different naturally;

The helical antenna frequency range is narrower: the structure of helical antenna is very simple and easy and cheap, but its receivable frequency range relative narrower;

The helical antenna size can't be reduced significantly: helical antenna is applicable to than low-frequency range for making it, so that its size must design is longer, can reach its purpose.

For solving above-mentioned shortcoming, the structure of the big frequency range antenna of tool of the present utility model is the helical antenna structure for a change, uses the integral type copper pipe instead as the antenna main structure, can effectively improve above-mentioned shortcoming.

Summary of the invention

Based on the shortcoming that solves the above prior art, the utility model is the structure of the big frequency range antenna of tool, it provides a copper pipe as the antenna main structure, and the antenna of non-traditional helical coil framework, the utlity model has that reception is stable, can to receive frequency range bigger, and the various advantages of dwindling antenna volume.

Another purpose of the present utility model is that the applicable frequency range of structure of the big frequency range antenna of tool of the present utility model includes: Digital Television signal (DVBT)/hyperfrequency (UHF) (474～860MHz), Global System for Mobile Communication (GSM) (900,1800,1900MHz), industry, science, medical treatment (ISM) (2.4GHz～2.5GHz, 5.8GHz), to reach the multiduty purpose of an antenna.

In order to achieve the above object, the structure of the big frequency range antenna of tool of the present utility model, it is made of a copper pipe in the antenna main structure, one end of described copper pipe is a closed state, the corresponding other end is to be provided with a screw thread in copper pipe body inside, and described screw thread can provide an aerial signal feed side corresponding connection.

The structure of the big frequency range antenna of tool of the present utility model, it is to have following advantage:

1, the copper pipe antenna receiving signal is very stable: because the copper pipe antenna can be not longer because of service time, cause elastic fatigue, length is maintained fixed forever, so received signal is very stable;

2, copper pipe antenna bandwidth broad: have the copper pipe of hollow structure, but its frequency acceptance band is wide than the conventional helical antenna;

3, the copper pipe antenna length can reduce significantly: the copper pipe antenna has extremely broad frequency acceptance band, still can reach the effect more preferable than conventional helical antenna so shorten length.

For further the utility model being had more deep explanation, be by following diagram, figure number explanation and detailed description of the invention.
