Abstract
The invention discloses a multi-linewidth gradually-varied Archimedes helical antenna and an implementation method therefor. According to the invention, the working band range of the Archimedes helical antenna can be enlarged, thereby enabling the Archimedes helical antenna to be able to achieve effective radiation of an electromagnetic wave in an ultra-wide band range. A plurality of groups of gradually-varied helical linewidth structures are employed to enlarge the bandwidth of the Archimedes helical antenna, thereby enabling the Archimedes helical antenna to be small in port impedance change in the ultra-wide band range and to be good in radiation pattern. Moreover, a low-frequency gain can reach a gain value of an Archimedes helical antenna with a common bandwidth. The plurality of groups of gradually-varied helical linewidth structures are employed to enable the bandwidth of the Archimedes helical antenna to exceed 30 frequency intervals. Moreover, the antenna can achieve good radiation pattern, gain and standing wave performances in a working band range, enables functions achieved by a plurality of original Archimedes helical antennas to be achieved by one antenna, reduces the number and sizes of antennas when ultra-wide band is in use, and saves the cost.

In passive detection field, the working band of system is all very wide, and antenna part is generally by multiple frequency range polytype antenna composition.If can design a kind of all channel antenna, it can cover the scope that original several antenna could cover, then can not only reduce the volume of system, can also reduce the cost of antenna.Therefore design bandwidth, simultaneously the Archimedian spiral antenna that meets the demands of electrical property, has extremely important meaning for Passive Detention System.
Summary of the invention
The object of the invention is the working band in order to expand Archimedian spiral antenna, enabling Archimedian spiral antenna realize good directional diagram, gain within the scope of the octave that 30 octaves are even larger.
The solution that the present invention adopts for its technical problem of solution is: according to the internal-and external diameter of the working band determination Archimedian screw radiator of antenna, adopt the Archimedian spiral antenna that many group gradual change spiral live width structure of modification are traditional, reduce the too much winding turns that original single live width causes, its innermost layer live width must adapt to high-frequency work, outermost layer live width must adapt to low frequency operation, other live width value is between inside and outside live width, total winding turns is between 20-30, and low frequency radiation dimensional requirement can be covered, utilize the winding turns of the live width of electromagnetic simulation software HFSS/CST analysis optimization many groups helix and each group helix simultaneously.Many groups gradual change spiral live width structure only needs to transform traditional single live width helix structure, the frequency bandwidth that several helical antenna just can reach can be realized on an antenna, original function realized by multiple antenna is replaced by an antenna, reduce superwide range internal antenna quantity and size on the whole, save cost simultaneously.
Compared with prior art, its remarkable advantage is in the present invention: (1) Archimedian spiral antenna working band can reach 30 octaves; (2) Archimedian spiral antenna antenna pattern within the scope of 30 octaves is good; (3) individual antenna instead of multiple traditional Archimedian spiral antenna, decreases antenna amount and installing space on the whole, has saved processing cost simultaneously.
