摘要
The far field behavior of a small wave size cylindrical microstrip antenna (CMA) has been originally analyzed for a small elevation angle, where a pronounced maximum has been found. Also it has been found that a similar maximum takes place in the far field of an electric dipole taken instead of the patch. It has been shown that the phenomenon originates to the far field behavior of the annular electric current given in the form of n = 1 azimuthally traveling wave harmonic held in the series representation of the electric dipole field. Approximate analytical expressions have been obtained describing the far-field components for two different polarizations. Also, the CMA radiation pattern is shown to bear similarities to the pattern of an electric dipole placed on a dielectric substrate surrounding a circular metal cylinder. © 2008, Electromagnetics Academy.
