| 摘要 |
The present invention provides a surface mount antenna, comprising: a base, comprising a roughly trapezoid insulator having a first main face, a second main face and end faces extending between the first main face and second main face; a ground electrode, mainly provided on the first main face of the base; first and second radiation electrodes, mainly provided on the second main face of the base; and a first connection electrode, a second connection electrode and a feed electrode, provided on end faces of the base; the first and second radiation electrodes facing each other with a slit in between, the slit being provided at a diagonal to all sides of the second main face of the base; an end of the first radiation electrode which is near to an end of the slit connecting to the ground electrode via the first connection electrode; the feed electrode being provided near to an end portion, with a gap in between, which is distant from an end portion of the first radiation electrode where the first connection electrode is connected; and an end portion of the second radiation electrode, which is a fixed distance from an end of the slit, connected to the ground electrode via the second connection electrode.
