Abstract
An aperture antenna includes a first base board and a second base board. The two base boards are separated through cascade structure. The first earthing unit is installed between the two base boards, the radiation unit is installed out side the first base board, and the second earthing unit is installed out side the second base board.The two earthing units are connected by a conduct department placed between them. The utility model satisfies the demands of customers through enlarging the earthing area by adding additional earthing units, and thus the pus of the antenna is maximized.
Description
[technical field]
The utility model is a kind of antenna, particularly a kind of microstrip slot antenna.
[background technology]
Because the product of wireless transmission is universal day by day, the user can not be subjected to environmental limit to utilize radio transmitting device, transmit or receive data and information, for radio transmitting device, no matter be personal digital assistant, mobile phone or mobile computer or the like, antenna is considerable assembly in the radio transmitting device, because the quality of antenna has considerable influence to the quality of wireless transmission and reception.
No matter traditional antenna is dipole antenna or helical antenna or the like, all occupy sizable volume, present trend and trend have not been met, so, in recent years, the principle design that this technical field is just used the lithographic plate antenna goes out the quite little microstrip antenna of volume, reaches the requirement of electronic installation transmission or reception data and information.
Microstrip antenna be system combination with wireless transmission on a little band plate, so not only volume is quite little, and manufacturing cost is also quite cheap, and because microstrip antenna does not need mechanical structure or other connector, so more can improve the reliability of wireless transmission.
General microstrip antenna is arranged in the various electronic installations, usually for cooperating the difference of various electronic installation operating frequencies, and need different band width and gain, but general microstrip antenna need meet various demands because of it, so its volume all assembles the structure of carrying with micro to being beneficial to.There are following two kinds of problems in general microstrip antenna: 1) gain satisfies the demands, but volume is inadequately little; 2) volume is enough little, but gain is not enough.
[summary of the invention]
Main purpose of the present utility model is to provide a kind of volume the little and big microstrip slot antenna that gains.
For reaching above-mentioned purpose, the utility model provides a kind of microstrip slot antenna, it comprises one first substrate and one second substrate, first substrate and second substrate are provided with at interval in stacking mode, and folder is established one first grounding parts between first substrate and second substrate, and be provided with Department of Radiation in the outside of first substrate, be provided with one second grounding parts in the outside of second substrate; And be provided with a conductive connection part between second grounding parts and first grounding parts.
Compared to prior art, the volume of the utility model microstrip slot antenna is enough little, and it is provided with two grounding parts, and the area of grounding parts is increased, thereby makes its gain also enough greatly, can satisfy client's demand.

Fig. 1 is the schematic perspective view of the utility model microstrip slot antenna under a view directions.
Fig. 2 is the schematic perspective view of the utility model microstrip slot antenna under another view directions.
[embodiment]
Please in conjunction with consulting Figure 1 and Figure 2, the utility model microstrip slot antenna comprises one first substrate 10 and one second substrate 40, and in present embodiment, first substrate 10 and second substrate 40 are laminar, and the dimensions of the two is consistent.And first substrate 10 and second substrate 40 are provided with at interval in stacking mode, and folder is established one first grounding parts 30 in the gap of first substrate 10 and second substrate, 40 interlayers, and be provided with Department of Radiation 20 in the outside of first substrate 10, in present embodiment, be provided with two Departments of Radiation 20 altogether, and two Departments of Radiation 20 are located at the surface of first substrate 10 in parallel mode.Be provided with one second grounding parts 50 in the outside of second substrate 40; And be provided with a conductive connection part 70 between second grounding parts 50 and first grounding parts 30, in present embodiment, conductive connection part 70 is a cylindrical wall shape structure, and the inside of conductive connection part 70 is provided with through hole.In addition, the surface that first substrate 10 is provided with Department of Radiation 20 is provided with a weld part 60, and this weld part 60 electrically connects with holding wire (figure does not show).
