The novel electric small size meander-line microstrip antenna has the advantage of having better antenna performance indicators.
Description
Technical field
The present invention relates to electronic technology field, be specifically related to a kind of Novel electric small size folding line microstrip antenna.
Background technology
Electric small-size: dimension a lot of object less of wavelength.
Microstrip antenna: on a thin-medium substrate, one side applies thin metal layer as ground plate, and another side photoetching caustic solution makes the metal patch of definite shape, utilizes the antenna that microstrip line or coaxial probe are formed patch.
For the microstrip antenna of electric small-size, in order to size reduction adopts miniature antenna technology usually.The miniaturization technology of microstrip antenna has following several:
(1) dielectric constant of medium substrate is improved;
(2) meander technology;
(3) short circuit loading technique;
(4) source network is attached with;
(5) application electromagnetic bandgap structure;
(6) left-handed medium is applied.
At present, the mode adjusting folding line microstrip antenna performance (as coupling, centre frequency etc.) mainly contains three: (1) changes length and the width of bending line segment; (2) position of distributing point is changed; (3) dielectric constant of medium substrate is changed.
For the microstrip antenna of electric small-size, due to adjustable limited space, the scope that dimensional parameters changes is less, and the performance parameter scope of adjustment is also subject to corresponding restriction.Therefore, the shortcoming of prior art is that the scope adjusting antenna performance is restricted.
Summary of the invention
The object of the present invention is to provide a kind of electric small-size folding line microstrip antenna with better performance index newly.
Technical scheme provided by the invention is: a kind of Novel electric small size folding line microstrip antenna, comprise a dielectric substrate, the upper surface of dielectric substrate has metal patch, metal patch is jagged meander line shape, also comprise the metal patch of dielectric substrate lower surface, the area of metal patch is S, and there is one piece of sheet metal dielectric substrate inside, and the area of sheet metal is S1.The area of described sheet metal S1 is 0.3S ~ 0.7S.
The area of described sheet metal S1 is by laterally changing sheet metal S1 size, or longitudinal change sheet metal S1 size, or transverse ends changes sheet metal S1 size, or longitudinal two ends change sheet metal S1 size, or surrounding changes the acquisition of sheet metal S1 size.
The invention has the beneficial effects as follows:
The invention provides a new electric small-size folding line microstrip antenna, there is better antenna performance index.
