Description
Technical field
The utility model relates to ultra-wideband antenna technical field, particularly a kind of Novel Ultra Wideband Antenna based on dual U-shaped groove.
Background technology
Antenna is part indispensable in wireless communication system, and its effect is to external radiation or receives electromagnetic wave, and ultra-wide band technology is as the positive dominate of one novel short distance high-speed radiocommunication technology.It utilizes the time domain short pulse signal of nanosecond to carry out radio communication, has that transmission speed is fast, security performance good, transmitting power is little and the advantage such as antijamming capability is strong.In February, 2002,3.1-10.6GHz is divided into civilian ultra wideband frequency by FCC (FCC).
At present, the method for designing of ultra-wideband antenna mainly contains: (1) changes the form of ground plate or radiation patch, as adopted spirality, circle etc., but complex structure, not easily process; (2) parasitic element is introduced, but can adding due to new construction, cause the size of antenna to become large, be unfavorable for the miniaturization of antenna.If Authorization Notice No. is the ultra-wideband antenna designed in the patent document of CN202633503U, radiation patch is fan-shaped, and ground plate is semicircle, and design is complicated, processing difficulties.Therefore, the ultra-wideband antenna designing a simplification and miniaturization has great importance.
Utility model content
The purpose of this utility model is to provide the ultra-wideband antenna, particularly a kind of Novel Ultra Wideband Antenna based on dual U-shaped groove that a kind of structure is simple, low-profile, cost of manufacture are low.
The technical scheme that the utility model adopts:
A kind of Novel Ultra Wideband Antenna based on dual U-shaped groove, it is characterized in that: comprise grounding plate (1), medium substrate (2), 50 Ω microstrip feed lines (3), impedance transformer (4), resonant element (5) and two U-lags (61,62).
Described a kind of Novel Ultra Wideband Antenna based on dual U-shaped groove, it is characterized in that: 50 Ω microstrip feed lines (3), impedance transformer (4) and resonant element (5) are positioned at the upper surface of medium substrate (2), and grounding plate (1) is positioned at the lower surface of medium substrate (2).
Described a kind of Novel Ultra Wideband Antenna based on dual U-shaped groove, is characterized in that: impedance transformer (4) is for trapezoidal, and two ends connect 50 Ω microstrip feed lines (3) and resonant element (5) respectively.
Described a kind of Novel Ultra Wideband Antenna based on dual U-shaped groove, is characterized in that: resonant element (5) for trapezoidal, and is carved with two U-lags (61,62).
Advantage of the present utility model is:
(1) each several part in the utility model is Common Shape, does not comprise the labyrinth such as arc, spirality, simplicity of design, is easy to processing.
(2) the utility model adopts the method spread bandwidth of cutting on resonant element, does not introduce other parasitic elements, low-profile, is conducive to the miniaturization of antenna.
(3) medium substrate of the present utility model adopts tetrachloro-ethylene material, and grounding plate, 50 Ω microstrip feed lines, impedance transformer, resonant element adopt copper foil material, and this bi-material market is common, cheap, makes the cost of manufacture of antenna low.
