Novel method to calculate antenna radiation patterns based on fixed-line-of-sight setting

Abstract:

Determination of antenna radiation pattern is an essential step for any communication systems. Although, there are several techniques available some of them are expensive, unreliable or complex. In this paper, a new measurement method of antenna radiation patterns that overcome some of these issues is presented and implemented. The method is based on acquiring the radiation intensity in different angular positions, based on fixed-line-of-sight setting, far-field measurement techniques and probabilistic analysis. The method provides a fast and simple mechanism for verifying antenna radiation patterns. The current method is used to determine the radiation pattern of a Yagi-Uda antenna with six parasitic elements of variable length and is compared with the theoretical models Delta-Gap and sinusoidal approximation of current for both planes electrical (E-Plane) and Magnetic (H-Plane).
