Introduction to Antenna Placement and Installation introduces the features of antennas and their integration on plane. The publication covers antenna siting and location, computational antenna modelling on constructions, size on sub-scale types of the airframe, full-scale flooring measurements and in-flight measurements.
the writer addresses the several levels within the strategy of constructing a complete antenna structure, in addition to overlaying person retrofits on current systems. She explains the physics of antenna placement qualitatively, hence obviating the requirement to appreciate advanced mathematical equations.

Creeping waves are particularly pertinent to aircraft, since most fuselages are of circular or elliptical cross-section. The waves travel around the curved surface, taking a number of paths known as geodesics. A geodesic is defined as the shortest route between two points on a mathematically derived surface that includes the points, and in the case of the earth’s surface, this would be a segment of a great circle cut. A great circle has the same circumference as the equator. Geodesics are sometimes defined as curves whose tangent vectors remain parallel if they are transported along it.

30 Great circle cuts. 31 Conical cuts. Conical Cuts If we imagine cuts parallel to the azimuth plane of the antenna (the equator in the case of a globe), we would get circles of smaller diameter as we move away from the equator. 31.

They are standard xy plots where the axes are plotted at right angles to each other. 3) is varied and the magnitude of the radiated power is measured.
