Antenna structure for polarization diversity reception has four antennas fitting together in a dimensional perspective with different polarization/orientation.

摘要

Several e.g. four antennas (1a-1d) form dipole pairs e.g. (1a/1b,2a/2b) in an X-shape with their polarization directions vertical to each other and make up a quasi star shape. These antennas are stacked in an antenna casing (10). Antennas polarized vertically and horizontally (1a,1c) and antennas polarized at -45 deg and +45 deg (1b,1d) are each assembled in one group.
