Point Source Radar

Simple Point Source Radar Antenna

To achieve the most accurate and precise radar performance or for best radio performance, an universal, mast antenna is proposed to fulfil the dual requirement.

A standard, very narrow conductive, metal loop stands tall as the basic antenna. It is lightly, electrically insulated an covered from its base to almost its full height, save for the tip, by a well insulated, conductive, reflective fitted, tubular, metal sheath.

The sheath should have enough exposure above its open end to emit a series of series of spherical wave fronts. It will also receive multi-directionally for a two way antenna system. Point the antenna tip in the direction of preferred transmission/reception. The wave would not be completely spherical without diffraction arcing its trajectory all the way around the tip.

A mast antenna’s focal length can be adjusted by sliding a parabolic reflector along the axis of the antenna. That would be concavely facing the transmitting direction of the antenna.

The development is similar to an optical, reflecting telescope.
