Abstract:
1. A surface mount antenna configured by mounting on a board a dielectric material on which electrodes are provided, characterized in that: said electrodes are formed to have a ground electrode and a feed electrode; and a ground mount pattern connected to the ground electrode of said electrodes and a feed mount pattern connected to the feed electrode of said electrodes are formed on said board with a predetermined distance between them; wherein a utilized frequency is adjusted by changing an impedance by varying a pattern width of a portion connecting the ground electrode of the electrodes and a GND pattern of a ground side of the board; and an impedance matching is performed by changing a capacitance based on a dielectric constant of the board by varying an area of a surface of a feed pattern at a position where the feed electrode of the electrodes and a feed side of the board are in opposing relation to each other.
