ABSTRACT:
An antenna of the long frame-type wherein the ratio between the long side and the short side is between 1:4 and 1:8 and the length of the long side is equivalent to one wavelength of the central frequency. One pair of short bars are deployed so that they are located at a distance corresponding to 1/4th to 1/40th of the distance from both end parts of the entire long side length of each long side element. The two end portions of the long side of the antenna is symmetrically bent with respect to a central portion such that the two end portions form an angle of 45 to 90 degrees with respect to the central portion and are parallel to each other.
