Journal ArticleDOI
The resonant cylindrical dielectric cavity antenna
TL;DR: In this article, an experimental investigation of the radiation and circuit properties of a resonant cylindrical dielectric cavity antenna has been undertaken, and a simple theory utilizing the magnetic wall boundary condition is shown to correlate well with measured results for radiation patterns and resonant frequencies.
Journal ArticleDOI
Resonant frequency of a circular disc, printed-circuit antenna
TL;DR: In this article, the resonant frequency of a planar, circular disc antenna was obtained in analytical form for a printed-circuit board, where the low profile antenna is separated from the ground plane only by a thin layer of dielectric material.
Journal ArticleDOI
The elliptical microstrip antenna with circular polarization
TL;DR: A theoretical analysis of an elliptical microstrip antenna is presented in this article, where it is shown that radiation from this antenna is left-hand or right-hand circularly polarized in a narrow frequency band when the eccentricity of the ellipse is small.
Journal ArticleDOI
A simple formula of current in dipole antennas
L. Shen,T.T. Wu,Ryan D. King +2 more
TL;DR: In this article, a simple and quantitatively accurate representation of the current distribution in a dipole antenna is derived, and numerical data are given and are found to be in good agreement with the experiment when h \geq O.15\lambda.
Journal ArticleDOI
An experimental study of the circular-polarized elliptical printed-circuit antenna
TL;DR: In this article, the authors investigated the design criteria which produced the best circular polarization for a printed-circuit antenna with varying eccentricities. But their focus was on the design of the antenna.
