摘要
To make improvements in a conventional slotted bow tie antenna to make it possible to (a) broaden the tuning frequency band, (b) function as a dual band antenna, without diminishing the “advantage of enabling a thin shape and possessing directivity”. When the symmetrical axis in the longitudinal direction of the bow tie shaped slot is set as x, and the symmetrical axis perpendicular thereto is set as y, a narrow and long parasitic element is placed over and across in the y axis direction, and this parasitic element is insulated electrically from a metal foil provided with a slot, using an insulator, for example. Further, by using two parasitic elements and arranging them in parallel while electrically insulating them from each other, the antenna can also function as a dual band antenna.
