Title: John Fraschilla: Innovator in Antenna Technology

Introduction

John Fraschilla is a notable inventor based in Hainesport, NJ (US). He has made significant contributions to the field of antenna technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of antenna systems.

Latest Patents

Fraschilla's latest patents include an "Antenna with compact LRU array" and an "Extendable/retractable antenna calibration element." The first patent describes an element support and thermal control arrangement for an active array antenna, which utilizes line-replaceable units (LRUs). This innovative design features a radiating-side liquid-cooled cold plate that lies parallel to a liquid-cooled TR coldplate. The antenna elements are supported and cooled by the radiating cold plate, while a beamformer is positioned between the two coldplates. Additionally, column coldplates are attached to the rear of the TR coldplate, creating bays for power LRUs to be fitted in thermal communication with the coldplates.

The second patent, the "Extendable/retractable antenna calibration element," involves an antenna array that works in conjunction with a ground plane for radiation. Calibration is achieved using extensible calibration antenna elements, such as monopole antennas. These calibration monopoles are typically retracted below the ground plane and are not energized. When calibration is needed, they extend above the ground plane to achieve mutual coupling with the array antenna elements. The calibration antenna can be extended or retracted using a vacuum, mechanical device, or electrical motor.
