Abstract :
The directional attenuators are devices with attenuation dependent on direction of propagation of RF energy. A new type of the directional attenuator was developed, designed and tested. The advantages of the new directional attenuators are low cost and low attenuation in forward direction, which is from 1 to 2 dB. The attenuation of designed directional attenuators in backward direction is from 7 to 20 dB. The attenuators were developed for frequency band from 2.4 to 2.48 GHz, e.g. for wireless networks according to standards IEEE 802.11b/g.
