Abstract: An omni directional coverage multibeam antenna relief on a ground surface having simple conical shapes to provide beam steering. One advantage of such a system is that the projected area is always constant and broadside to the intended direction resulting in limited scan loss effects. In the case of a cylinder as the conical shape, z-axis symmetry provides a constant antenna aperture projection in any azimuthal direction. Using this geometry, high level, side lobes are reduced considerably because of the natural aperture tapering from dispersion effects. Coverage area and power can be controlled by changing the ground surface angle and by selectively activating different antenna beam positions around the circumference of the ground surface, and by selectively changing the phase relationship between a given set of antenna beams.

Abstract: A self-resonant vertically polarized folded unipole antenna for long wave (LW), medium wave (MW) broadcasting and for the 160 meter amateur radio band with a grounded tower connected to radially descending fold wires terminated near the base of the tower in an open polygonal ring, possibly a C-ring with a reactive load in series with this ring. This reactance cancels the reactive component of the antenna input impedance causing the input impedance to appear resistive at the feed point. This leads to outstanding linearity and bandwidth up to and possibly exceeding plus or minus 16 kHz, sometimes exceeding plus and minus 20 kHz. The antenna is particularly useful for AM broadcasting of high quality music with response capable of being better than that of FM.

Abstract: Omnidirectional cellular coverage may be provided by installing four 90 degree antennas on the sides of a tower. However, in a prior system pattern uniformity will be destroyed by nulling effects if the tower width causes the lateral separation between adjacent antennas to be large. Nulling effects in areas of overlap between beams of adjacent antennas are avoided by providing an omnidirectional pattern characterized by signal polarization which changes with azimuth. Cross polarization of adjacent antennas is achieved by providing North and South antennas with +45 degrees linear polarization and East and West antennas with -45 degrees linear polarization (alternating antennas with right and left circular polarizations may also be used). Portable cellular receivers for use with the antenna system may typically utilize antennas with either vertical or horizontal linear polarization.

Abstract: In an umbrella top-loaded monopole (UTLM) antenna, the charge distribution n top-load radials increases approximately linearly from the top of the antenna because the activated top-load wires are separating from the tower and each other at the same time they are getting closer to ground. The UTLM antenna of the invention incorporates a top-load configuration in which top-load elements, whether they be radiating or receiving, are arranged in sections of rhombic-shaped frames that originate at the top of the antenna and that extend away from the antenna towards the antenna's base where, at those points of the configuration furthest from the antenna tower and closest to ground at least two top-load elements converge to shield each other and hence reduce charge density. The top-load sections are disposed between the vertical guy wire planes of an antenna to ease their installation, repair and maintenance. The self-shielding effect of the invention permits an antenna to operate at considerably higher voltage.

Abstract: An antenna mounting system has a pole secured at a first end to a base. A platform is connected to the pole via a tiltable joint which is rotationally fixed with respect to the pole. An antenna is secured to the platform, having a beam which is aligned to a desired elevation and azimuth orientation. Three flexible cables are connected at their first ends to the platform and at their second ends to a fixed reference plane mounting member which is rotationally fixed to the pole nearer its first end. The force of high winds will cause the pole to bend and, if unaccounted for, change the planar orientation of the platform and mispoint the beam. The platform, mounting member, and cables form a system of parallelograms whose sides remain parallel when the pole is deflected. Thus, the platform maintains its original angular orientation as the pole bends, preserving the desired orientation of the beam.
