摘要
Are arranged substantially parallel to the (2,4) folded dipole antenna element at a distance shorter than half the wavelength used. The antenna elements (2,4) are connected to the combiner (16) via (12, 14) feed lines having different lengths. The signal received by the antenna elements (2,4) a radio wave arriving at the (2,4) antenna element input from the front of the combiner (16) between the length of the feed line (12, 14) is, (16a , received signal is in phase with 16b), the receiving antenna element at (2,4) a radio wave arriving at the (2,4) antenna elements from the back and a reverse phase (16a, at 16b) input synthesizer (16) you have chosen to be.
