MULTIFREQUENCY INTEGRATED TYPE ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a multifrequency integrated type antenna such that a plurality of antennas having different directivities can be integrated without spoiling the directivities. SOLUTION: The multifrequency integrated type antenna 1 has antenna elements 3 and 4 formed on a surface of a dielectric substrate 2 and a first ground electrode 5 integrally fixed on the reverse surface of the dielectric substrate 2. Further, a second ground electrode 6 is provided and the dielectric substrate 2 and first ground electrode 5 are installed at a specified angle 9 to the second ground electrode 6. The size of the first ground electrode 5 is set to≤1/4 of the center wavelength of a low frequency band. COPYRIGHT: (C)2007,JPO&INPIT
