Latest Patents

Lindqvist's latest patents include advancements in polarization isolation in antennas. This invention presents an antenna with improved polarization isolation, featuring at least two columns of rectangular micro-strip or patch elements, each exhibiting a single, linear polarization. The columns are designed to radiate elements at approximately +45 or -45 degrees. By combining these columns, a dual-polarized antenna is achieved, with a herringbone pattern that minimizes coupling between patches, thus enhancing isolation between the two states of polarization. This design allows for the separate utilization of the two linear states for polarization diversity. Additionally, the antenna structure compensates for pointing errors due to unsymmetrical ground planes.

Another significant patent involves a microstrip antenna with a metal frame designed to control the antenna lobe. This device is particularly useful for microwave antennas, as it helps to suppress cross-coupling between polarizations in dual-polarized antenna elements. The metal frame can be angled to achieve the desired lobe width and is positioned around each antenna element on the ground plane. This innovation allows for precise control of the antenna lobe, independent of the ground plane size.
