<P>PROBLEM TO BE SOLVED: To provide a multiple-resonance antenna which is mainly applied to mobile communication radio communication devices at a microwave band and suitable for surface mount. <P>SOLUTION: A high frequency patch antenna electrode 102 and a low frequency patch antenna electrode 103 are arranged apart from each other by a gap on one main surface of a dielectric block 101 and feeding line electrodes 104, 106 are electromagnetically connected to the respective patch antenna electrodes 102, 103. Each of the feeding line electrodes 104, 106 is connected to each of feeding terminal electrodes 105, 107 and connected to each of input/output lines 121, 122 in every frequency band of a substrate 120, thereby realizing the multiply-resonance surface-mounted antenna 100 capable of coping with two frequency bands. <P>COPYRIGHT: (C)2004,JPO |
