Title: Landon L Rowland: Innovator in Antenna Technology
Introduction
Landon L Rowland is a notable inventor based in Westford, MA (US), recognized for his contributions to antenna technology. With a total of 7 patents, he has made significant advancements in the field, particularly in phased array antennas.
Latest Patents
Among his latest patents is the "Beamsteering technique to minimize sidelobes due to phase quantization in a phased array antenna." This innovative design for an Active Electronically Scanned Lens Array reduces costs while maintaining performance. By replacing traditional transmit/receive (T/R) modules with low-cost phase shifters, Rowland addresses the challenge of periodic phase quantization errors that create quantization lobes. His approach introduces a phase offset at a T/R module, which is then corrected at each radiating element, effectively minimizing these lobes.
Another significant patent is the "Dual-polarized wideband radiator with single-plane stripline feed." This invention features a plurality of antenna elements, each equipped with orthogonally coupled notch elements linked to an interleaved stripline-to-slot feed structure. The design allows for a phased array antenna capable of receiving electromagnetic signals with orthogonal polarization, providing wideband performance without requiring electrical continuity between adjacent elements.
