Abstract
Ten radiation antenna elements project from a straight feeder stripline. A first set of radiation antenna elements each having a rectangular shape project from a first side edge of the feeder stripline such that the radiation antenna elements incline at an angle of about 45 degrees. The distance between adjacent radiation antenna elements is equal to an guide wavelength &lgr;g and the length of each radiation antenna element is equal to &lgr;g/2. Similarly, a second set of radiation antenna elements each having a rectangular shape project from a second side edge of the feeder stripline. Each of the radiation antenna elements in the second set is disposed to be separated by &lgr;g/2 from a corresponding one of the radiation antenna elements in the first set. Each of the radiation antenna elements is connected to the corresponding side edge of the feeder stripline via a corner thereof.
