Title: Arthur D. Yaghjian: Innovator in Antenna Technology
Introduction
Arthur D. Yaghjian is a notable inventor based in Concord, MA (US). He has made significant contributions to the field of antenna technology, holding a total of 2 patents. His work has advanced the understanding and application of antennas in various technological domains.
Latest Patents
Yaghjian's latest patents include the "Electrically small supergain endfire array antenna." This invention features an electrically small supergain endfire transmitting and receiving array antenna that comprises at least one first resonant element with a first input terminal. The first resonant element is driven by a power supply voltage supplied at the first input terminal. Additionally, the antenna includes at least one second resonant parasitic element with a second input terminal, which is shorted and spaced less than about 0.25λ from the first resonant element at any corresponding point. This innovative antenna achieves a gain of at least 6 dB and ka<1.0.
Another significant patent is the "Apparatus for scanning and measuring the near-field radiation of an antenna." This invention allows for the measurement of the near-field radiation of an antenna, enabling the determination of its far-field radiation characteristics. Utilizing the principle of the Foucault pendulum, the apparatus employs a bob attached to a long pendulum arm that is free to rotate. The rotation of the earth causes an apparent rotation of the swing plane of the pendulum. By attaching a field sensing probe to the pendulum bob and mounting the antenna under the Foucault pendulum, the entire antenna aperture can be scanned without moving the antenna.
