2 Some Antenna Fundamentals Antenna engineering is rooted in the classical electromagnetic theory. Thus, knowledge of the basic principles of electromagnetism is required, such as Maxwell’s equations, the electromagnetic field behavior at medium interfaces, the retarded potentials, transmission-line and ...

Pyramidal Horn Design Introduction This application calculates the optimum design parameters for an X-band pyramidal horn. Based on example 13.6, page 782 of Antenna Theory, Analysis and Design , Constantine A. Balanis, 3 rd Edition. Parameters The...
A typical design window for the synthesis of a horn antenna is shown inFigure 2. Initially, the user inserts general design parameters like frequency ranges and polarizations. Depending on the user’s demand and specifications (for example, cross-polar level, bandwidth) the type of horn is cho...
It is to be appreciated, however, that other wave equations are equally amenable to the teachings herein. Using the direct boundary element formulation, the acoustic pressure at any point of a homogeneous fluid domain containing no acoustic source can be expressed in terms of the acoustic pressure...
A preliminary investigation of miniature loudspeaker high frequency resonance and its impact to antenna radiation performance The objective of this study is to investigate the near field coupling between a miniature loudspeaker and a nearby antenna. The analysis focuses on the lou... XL Chen - IEEE...
The double ridge antenna[3] is designed using equations in which the dimensions depends mainly on operating frequency of antenna. The results are obtained through simulation by using Ansoft HFSS, a commercially available simulator.Lavanya YChandrakala...
Antenna theorycorrugated antennascorrugated horn antennascorrugated waveguidesAn approximation of the far-field radiation pattern of the corrugated-conical horn, by integration of the aperture field, augmented with perimeter-matched quadratic radial phase, is sufficient to establish a baseline design for the...
