DECOUPLING APPARATUS FOR AN AERIAL ARRAY |
摘要 |
Attenuating apparatus is provided for reducing disturbance between transmitting and receiving aerials mounted vertically one above the other. Attenuation is achieved by a grounded screen (1) and a spacer, both mounted between the aerials. The screen is provided with cutouts (6) having a pitch (c) of lambda /2, where lambda is the mean frequency of the pertinent frequency band and lambda /4 is the depth (d) of the cutouts. The length of the spacer is 0.70 lambda . |
