<p>PROBLEM TO BE SOLVED: To provide a small-sized antenna whose size is reduced by using the resonance phenomenon in a high speed wave leakage mode, which is mounted on a printed circuit board with the surface mount technology and can be built on a dielectric material whose specific dielectric constant is selected to be 2-5. SOLUTION: The antenna consists of a high speed wave vibrator A and a multilayer ground device B. The high speed vibrator A is provided with a three-dimensional dielectric body and with a microstrip A0 that is wound on the surface of the three-dimensional dielectric body, one end of which is used for signal input/output terminals, the other end of which is open and whose winding method can be adjusted depending on a desirable radiation pattern. The multi-layer grounding device B is placed under the high speed wave vibrator A, mainly consists of a plurality of parallel layers B1-B9 and of a plurality of via-holes B10-B17, where all inner fades of grooves 1-4 of a plurality of the parallel layers B1-B9, all inner faces of a plurality of the via-holes B10-B17 and all other outer faces are used for metallic grounding planes.</p> |
