The most common form is shaped like a dish and is popularly … See more Parabolic antennas are distinguished by their shapes: • Paraboloidal or dish – The reflector is shaped like a paraboloid truncated with a circular rim. This is the most common type. It radiates a narrow pencil-shaped beam along the axis … See more In parabolic antennas, virtually all the power radiated is concentrated in a narrow main lobe along the antenna's axis. The residual power is radiated in sidelobes, usually much smaller, in other directions. Since the reflector aperture of parabolic antennas is much … See more The operating principle of a parabolic antenna is that a point source of radio waves at the focal point in front of a paraboloidal reflector of conductive material will be reflected into a collimated plane wave beam along the axis of the reflector. … See more The radiation pattern of the feed antenna has to be tailored to the shape of the dish, because it has a strong influence on the aperture efficiency, which determines the antenna gain (see … See more The directive qualities of an antenna are measured by a dimensionless parameter called its gain, which is the ratio of the power received by … See more The idea of using parabolic reflectors for radio antennas was taken from optics, where the power of a parabolic mirror to focus light into a … See more
