Chip antenna |
摘要 |
A chip antenna capable of reducing the spiral pitch of an antenna line to be smaller than that of a conventional one. Conductor patterns are electrically connected sequentially in series through via holes so as to form a spiral antenna line. The antenna line has a winding axis which is arranged either in a zigzag manner or along a straight line. Adjacent wound portions have an equal diameter or width or the adjacent portions may have unequal widths. Since adjacent via holes are arranged in a staggered arrangement with each other, the distance between the adjacent via holes is larger than the spiral pitch of the antenna line, allowing the adjacent portions to be closer together than a conventional chip antenna, thereby allowing the resonance frequency to be reduced.
