Abstract
A surface mount antenna is configured by mounting on a board a dielectric material on which electrodes are provided, wherein an antenna element comprises the electrodes having a ground electrode and a feed electrode, and a ground mount pattern connected to the ground electrode of the electrode and a feed mount pattern connected to the feed electrode of the electrode are formed on the board with a predetermined distance in-between. A frequency is adjusted by changing impedance by varying a pattern width of a portion connecting a ground electrode of the electrodes and a GND pattern of a ground side of the board, and an impedance matching is performed by changing capacitance based on dielectric constant of the board by varying area of a surface of a feed pattern at a position where a feed electrode of the electrodes and a feed side of the board are in opposing relation.
