Description
Technical field
The present invention relates to a kind of ultra broadband symmetry biconical antenna, be specifically related to the ultra broadband that a kind of bus is composite curve symmetrical
Biconical antenna, belongs to wireless communication field.
Background technology
At present, super-broadband tech is an important development direction of wireless communication field, has had become as domestic and international communication
One of hot issue in recent years and research direction.Super-broadband tech is paid close attention to the most widely, is primarily due to it high
Transfer rate, the advantage such as low-loss and big information capacity.The development of super-broadband tech also makes the design of ultra-wideband antenna
Becoming more and more important, the most the ultra-wideband antenna of various ways is suggested, and much has been used in the middle of Practical Project.
Biconical antenna, as a kind of common ultra-wideband antenna, is widely used to radio communication, SAR radar imagery, life
In thing medical science and wireless frequency spectrum detection.But the common impedance operator of limit for length's biconical antenna that has has closely with the size of antenna
Close, and LF medium frequency is of a relatively high, it is impossible to well contain the frequency range used in Modern Communication System.Therefore, for
Realizing the improvement of low frequency characteristic, generally require the size increasing antenna, and antenna weights also sharply increases, being unsuitable for should
With；And realize the improvement of high frequency characteristics, then need to reduce the size of antenna, increase the actual difficulty of processing of antenna.Thus, if
Obtain there is the small size of wide bandwidth, lightweight biconical antenna be more difficulty.
Summary of the invention
The present invention solves that the size of existing biconical antenna and weight cannot take into account the problem of high frequency characteristics and low frequency characteristic, enter
And the ultra broadband symmetry biconical antenna that a kind of bus is composite curve is proposed.
The present invention solves that the problems referred to above adopt the technical scheme that: the present invention includes two cone tables, two cone tables by
Hour-glass in shape setting under up to, each cone table is the second of binomial curve by the first cone table that bus is straight line and bus
Cone table forms, and the end face of the first cone table and the bottom surface of the second cone table link into an integrated entity.
The invention has the beneficial effects as follows: present configuration is simple, and size is less, all can realize in very high frequency(VHF) to microwave band
Good impedance matching, had both remained the high frequency characteristics of common biconical antenna, further through binomial curve part to low frequency part
Radiation characteristic is improved.Compared with the ordinary conical antenna of comparable size, bandwidth significantly increases, and low-frequency cut-off frequency
Relatively low, in working band, omni-directional is good, and gain is maintained at about 3dBi, in bandwidth of operation, and the transmitting of this antenna or connect
Collection of letters amplitude of variation is little, and has linear phase, and group delay property is preferable simultaneously so that this antenna frequency domain characteristic and time
Territory characteristic can meet the requirement of broadband wireless communications, can be used as occurring antenna to use, can use as reception antenna again.Combine
Upper described, the present invention can be in multiple systems such as wireless communication field, SAR radar imagery, biomedicine and wireless frequency spectrum detections
System uses.
