Title: Innovations of Richard E. Twogood: A Pioneer in Antenna and RFID Technology
Introduction
Richard E. Twogood, an inventive mind located in San Diego, CA, has made significant strides in the fields of antenna design and RFID technologies. With a total of six patents to his name, Twogood is recognized for his innovative contributions that enhance the functionality and security of communication systems.
Latest Patents
Among Richard's latest patents is the invention titled "Broad Band Half Vivaldi Antennas and Feed Methods." This innovation features a single Vivaldi antenna plate positioned over a ground plane, allowing it to achieve a 50-ohm impedance. Additionally, it can incorporate two or more single plates over a ground plane to meet different impedance requirements. Notably, unbalanced 50-ohm transmission lines, such as coaxial cables, can be used for direct feeding of the antenna.
Another remarkable patent is the "Secure Passive RFID Tag with Seal." This system comprises a base station and at least one passive RFID tag, featuring a fiber optic cable that is sealed at both ends. The middle portion of the cable forms an external loop that can be secured to an object. This innovative tag transmits and receives optical signals through the fiber optic cable. It is designed such that the cable becomes damaged or broken if tampering is attempted, altering the optical signal significantly. This unique mechanism allows the tag to transmit a radio signal to the base station only when the optical signals match.
