Abstract
The utility model discloses a kind of dual polarized antenna of cordless telephone main frame, comprise the antenna electrode line be electrically connected on cordless telephone host mainboard, the positive and negative of described cordless telephone host mainboard is respectively arranged with the two antenna negative plates oppositely extended with the bearing of trend of antenna electrode line.The utility model has can strengthen transmission and Received signal strength, obtains the advantage of good communication distance.
Description
Technical field
The utility model relates to cordless telephone, especially relates to a kind of can enhancing and sends and Received signal strength, obtain the dual polarized antenna of the cordless telephone main frame of good communication distance.
Background technology
Cordless telephone is a kind of automatic telephone unit.This telephone is made up of main frame and slave two parts.Main frame accesses telephone network by telephone wire, and slave keeps communicating by radio channel and main frame, during use, main frame is accessed cable telephone network, and user can leave the far away or rice up to a hundred of tens meters, main frame, utilizes slave to listen to and dialed phone.The speech range of traditional telephone still can not meet the needs of people.
Utility model content
For solving the problem, the purpose of this utility model is that providing a kind of can strengthen transmission and Received signal strength, obtains the dual polarized antenna of the cordless telephone main frame of good communication distance.
The utility model is realized by following technical measures, a kind of dual polarized antenna of cordless telephone main frame, comprise the antenna electrode line be electrically connected on cordless telephone host mainboard, the positive and negative of described cordless telephone host mainboard is respectively arranged with the two antenna negative plates oppositely extended with the bearing of trend of antenna electrode line.
As a kind of optimal way, described two antenna negative plates are symmetrical arranged and at same plane.
As a kind of optimal way, described antenna electrode line is linear, snakelike or spirality.
As a kind of optimal way, the total length of described antenna electrode line and an antenna negative plate is 1/4 wavelength of Antenna Operation centre frequency.
As a kind of optimal way, the frequency range of Antenna Operation is 1.88 to 1.9GHz, and the total length of described antenna electrode line and an antenna negative plate is for being 41mm.
The utility model can strengthen emissive porwer and the efficiency of antenna greatly, and unobstructed for the outdoor of common cordless telephone communication distance is enhanced to 1000 meters.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is sense figure and the signal gain schematic diagram of the utility model embodiment;
Fig. 3 is the signal echo resolution chart of the utility model embodiment.
Embodiment
Contrast accompanying drawing below in conjunction with embodiment the utility model is described in further detail.
The dual polarized antenna of a kind of cordless telephone main frame of the present embodiment, please refer to Fig. 1, comprise the antenna electrode line 3 being welded on antenna positive pole on cordless telephone host mainboard 2, the positive and negative of described cordless telephone host mainboard 2 antenna negative pole is welded with the two antenna negative plates 1,4 oppositely extended with the bearing of trend of antenna electrode line 3 respectively.
This antenna structure can strengthen emissive porwer and the efficiency of antenna greatly, and unobstructed for the outdoor of common cordless telephone communication distance is enhanced to 1000 meters.Fig. 2 is sense figure and the signal gain schematic diagram of the present embodiment; Fig. 3 is the signal echo resolution chart of the present embodiment.
