Abstract :
In this paper a design for a broadband, light weight and low cost smart shield frequency selective device is proposed. The device consists of a dual layer printed circuit board patch array and is capable of absorbing WLAN signals in the frequency range around 5.5 GHz, whilst allowing almost unitary transmission outside this range, for example the GSM frequency band ranging from 0.8 to 2.1 GHz. Therefore it can effectively be utilized in telecommunications, radomes and as a shielding structure in electronic devices.
