Abstract
Disclosed is a multiple-resonant surface-mounted antenna used for a radio device for mobile communication in a microwave band. A high frequency and a low frequency patch antenna electrodes are arranged apart from each other on one main surface of a dielectric block and a feeding line electrode is electromagnetically connected to the respective patch antenna electrodes. Each feeding line electrode is connected to each feeding terminal electrode and connected to each input/output line in every frequency band of a substrate, thereby realizing the multiple-resonant surface-mounted antenna capable of coping with two frequency bands.
