Title: Innovations of John C. Herper

Introduction

John C. Herper is a notable inventor based in Glen Cove, NY (US), recognized for his contributions to antenna technology. With a total of five patents to his name, Herper has made significant advancements in the field of telecommunications.

Latest Patents

One of his latest patents is the "Coaxial Collinear Element Array Antenna." This invention utilizes an array of collinear coaxial lines made from standard size brass tubing, with brass rods inserted to establish each half-wavelength coaxial section. A coupler positioned between each half-wavelength section supports the outer conductor and provides passages for the inner conductor. The inner conductors of the transmission line elements are soldered to the outer conductors of adjacent elements, ensuring that all elements are excited with the same phase and polarity. The air dielectric between the inner and outer conductors allows for a transmission line wavelength equal to that of free space, resulting in an antenna gain greater than that achievable with solid dielectric supporting the inner conductor.

Another significant patent is the "Phased Array Antenna Method and System for Adaptively Positioning Nulls." This system employs an auxiliary antenna in conjunction with a correlation receiver to determine the gain in amplitude and phase of the antenna pattern at the location of an interfering source. The gain is then used, along with the known gain at the peak of the main lobe of the antenna, to compute coefficients of sinusoidal perturbation functions. These functions are applied to the phase function of the antenna to establish a null in the direction of the interfering source.
