“…The contemporary widespread presence of wireless transmission devices fostered research in devising spatial filters for Wi-Fi, WiMax, Bluetooth, LTE, UWB, ISM-band and X-band signals [3]- [9]. Such filters are FSS's realized on printed circuit boards (PCB's) by printing and etching either one face (single layer [7]) or both faces (double layer) of the board with a periodic metal pattern. The resulting transmission coefficient of the FSS may exhibit a large stop-band [4], a pass-band [5], one stop-band [6], two stop-bands [7], [8], three stop-bands [9] or even five stop-bands [10].…”

“…One face of the PCB contains a rectangular periodic pattern of fan-shaped cross dipoles and the other face contains a pattern of rectangular rings still arranged periodically, with the same spatial period in the two orthogonal directions. The structure has been obtained by a modification of one recently proposed by the same authors in [7] and it features two notch frequencies.…”

Frequency Selective Surface With Two Quasi-Independent Notch Frequencies

A double-layer frequency selective surface (FSS) built on FR4 substrate exhibiting two notch frequencies in the 0-10-GHz range is introduced. Recently published examples demonstrate that further research needs to be undergone for obtaining separate tuning of the resulted notch frequencies. Thus, this issue is addressed in this paper: the notch frequencies can be quasi-independently set by appropriate values given to the geometrical parameters of the two metal patterns in the unit cells of the structure. The FSS behavior is stable with respect to the angle of incidence of impinging electromagnetic waves up to 45 • , as proved by simulation and validated by experiments. INDEX TERMS Frequency selective surface (FSS), notch filter, angular stability.
