Title: The Innovations of Robert G Riddle

Introduction

Robert G Riddle is a notable inventor based in San Diego, CA. He has made significant contributions to the field of communications technology, holding a total of 9 patents. His work focuses on advanced methods and systems that enhance communication efficiency and effectiveness.

Latest Patents

One of Riddle's latest patents is titled "Method for dynamically routing frequency hopping signals in a multiple carrier communications system." This innovative method involves routing a frequency hopping signal to one of two transmitting antennas in a multiple carrier communication system. The process includes storing known a-priori information regarding frequency hopping signal assignments, scanning a transmitter frequency and antenna path assignment table, and assigning the frequency hopping signal to an available path on the other antenna. Additionally, the method determines whether the assigned path conflicts with existing frequency assignments and preempts the antenna assignment when necessary.

Another significant patent is for a "Conformal, low RCS, wideband, phased array antenna for satellite communications applications." This phased array antenna consists of multiple spiral arm antenna elements arranged in a triangular lattice geometry. The design aims to increase bandwidth while reducing the radar cross-section (RCS) of the antenna through tight coupling of the elements.
