<P>PROBLEM TO BE SOLVED: To provide a multi-band patch antenna which has a stable and uniform characteristic in multiple bands. <P>SOLUTION: The antenna includes a skeleton slot radiating means 65 for irradiating electromagnetic waves, a current supply means 64 for transmitting a signal current to the skeleton slot radiating means 65, and a means 61 for reflecting radiation wave behind the skeleton slot radiating means 65. The skeleton slot radiating means 65 has a current supply point connected to the current supply means 64, a first conductive loop 66 having a symmetric shape with respect to the current supply point as a center, and second conductive loops 67 provided to both outer peripheral parts of the first conductive loop 66. <P>COPYRIGHT: (C)2003,JPO |
