The array antenna is proposed for the reception antenna of the digital terrestrial television broadcasting in Japan. The ultra low profile unbalanced fed inverted L antenna on parallel conducting wires is used as the driven element and two wires are located at the forward and backward directions of driven element. In the case of antenna size of 320 mm by 83 mm by 148 mm, the return loss bandwidth larger than 10 dB is satisfied from 480 MHz to 650 MHz. The directivity becomes 6.0 dBi to 7.77 dBi at this frequency band. In the numerical analysis, the electromagnetic simulator WIPL-D based on the method of moment is used.
