The finite‐difference time‐domain method (FDTD) is first applied to investigate the reflection and radiation properties of a finitely long coaxial antenna with circumferential slots on its outer surface. The end effect and multislot effect intractable for the moment method and mode‐matching method are analyzed efficiently and demonstrated in detail. According to the accurate analysis, the circumferential slots have a strong influence on the characteristics of the antenna. This effect can be used to effectively adjust the impedance matching and radiation pattern of the antenna. The verification of the method is also presented by reference to the experiment and the literature. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 21: 35–39, 1999.

Abstract. A thick monopole antenna fed by a circumferential slot cut on the outer conductor of a coaxial cable is studied with rigorous field theory in this paper. In our analysis we consider not only the higher-order modes inside the coaxial cable but also the nonuniform distribution of the electric field in the slot. The coupled integrodifferential equations are formulated for the evaluation of the current distribution on the antenna surface as well as the electric field distribution in the slot. The restriction of the slot width and the radii of the antenna are removed from the analysis. The effect of the slot width on the electric field distribution in the slot, the current distribution on the outer conductive surface of the antenna, and the input admittance viewed in the coaxial cable are presented and discussed. The calculated input admittance is in good agreement with the experimental result.

“…A more fundamental geometry of a coaxial line with a single circumferential slot was also studied by Chang [1973] to obtain an equivalentcircuit representation. Recently, a coupled-integralequation approach has been used to analyze the DFES antenna [Cho et al, 1993]. Even though the radiation characteristics and the reflection coefficient of the DFES antenna are well understood, in this paper we wish to obtain another new solution for the basic DFES antenna by using the Fourier transform and mode matching.…”

Abstract. We revisit the radiation characteristics of a dielectric-filled edge-slot (DFES) antenna, which is made by circumferentially removing the outer conductor of a coaxial line. The Fourier transform and the mode-matching technique are utilized to obtain a new solution in a fast converging series. A dominant-mode solution for the reflected power and the radiation field is given in a simple form. The numerical investigation is performed to show the behavior of the antenna input impedance and the radiation pattern. IntroductionWe consider the problem of radiation from a coaxial line whose outer conductor is circumferentially removed. This geometry is referred to as a basic dielectric-filled edge-slot (
