Title: Arlen K Johnson: Innovator in Microwave Technology

Introduction

Arlen K Johnson is a notable inventor based in New Providence, NJ, with a focus on microwave technology. He holds three patents that showcase his innovative contributions to the field. His work has significantly impacted the design and functionality of microwave devices.

Latest Patents

One of Johnson's latest patents is the "Folded Interdigital Notch Filter." This invention features an interdigital resonant cavity filter structure that is folded to create two adjacent chambers. These chambers are physically positioned side by side and electrically connected in series. A center plate divides the two chambers, allowing them to function as one resonant cavity. Each chamber includes interdigital resonators that contribute to the overall resonant cavity, producing a band pass filter action. The filter structure's input is applied through a port of a circulator, with the output taken from another port, ensuring high-quality notch filter operation.

Another significant patent is the "Microwave Circuit Device and Method for Fabrication." This method involves fabricating microwave devices by conforming a block of dielectric material to the required physical configuration. The block is then coated with electrically conductive material, and portions of this coating are removed to implement the desired microwave device. One example of this method is an interdigital bandpass filter, where the block is shaped and drilled to define the filter's physical configuration. The interiorly-coated drilled holes serve as resonator rods within a microwave cavity, allowing for fine-tuning to achieve the desired center frequency.
