| Abstract: | Starting from the basic electromagnetic theory,this paper theoretically analyzed radiation modes of leaky coaxial cable(hereinafter LCX in short) and deduced mathematical expression of its radiation fields.The problem was discussed that how to restrain the high mode radiation field of LCX and expand its single mode radiation band based on the conditions that only single mode radiation generated.After that,a method was explored for expanding the single mode radiation bandwidth of LCX with zigzag slots,providing a practical approach to apply LCX in ultra wide-band communication.The conclusion is significant for the design and use of LCX application in ultra wide-band communication. |
