发明名称 POLARIZED WAVE DIVERSITY DIPOLE ANTENNA
摘要 PROBLEM TO BE SOLVED: To provide a polarized wave diversity dipole antenna having a large amount of coupling attenuation between the polarized waves. SOLUTION: A crossover angle between two dipole antenna elements 1a and 2a for radiating the polarized waves having different polarization angles is in a range of 75°to 85°. The amount of coupling attenuation between the polarized waves can be enlarged by eliminating the influence of reflection. COPYRIGHT: (C)2004,JPO
