In this paper, a two-and-a-half dimensional analytical regularization method (2.5D ARM) was proposed to analyze reflector antennas for microwave, millimeter wave or ultra wide band applications.Abstract:
A novel and efficient approach, which is called two-and-a-half dimensional Analytical Regularization Method (2.5D ARM), is proposed to analyse reflector antennas for microwave, millimeter wave or ultra-wide band applications. To present computational performance of the proposed method, its results are compared with well known Physical Optics (PO) and Method of Moments (MoM) solutions for a PEC hollow cylinder and an open-ended corner reflector. Moreover, radiation pattern of a ridged horn fed parabolic reflector antenna is measured to validate the method experimentally. It is observed that either the simulated or the measured data and the 2.5D ARM results are in close agreement with each other.read more

Spatial Filtering in Planar Near Field Antenna Measurement System and Comparison of Two Gain Calculation Approaches
TL;DR: In this article, a planar near field antenna measurement system with 4 m x 1.8 m rectilinear scanning area is introduced for evaluating far-field radiation characteristics and gain of directive antennas which are physically large and heavy.
GTD analysis of reflector antennas with general rim shapes: Near and far field solutions
TL;DR: A map, drawing or chart is part of the material being photo- graphed and the photographer has followed a definite method in “sectioning” the material as mentioned in this paper, where it is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps.
