Grating Lobes Reduction Using a Multilayer Frequency Selective Surface on a Dual-Polarized Aperture Array Antenna in Ka-Band

This paper presents a multilayer frequency selective surface for a dual-polarized aperture array antenna in Ka-band. The 8×8 elements of the array are cylindrical open cavities with a diameter of 0.6λ 0 at 30 GHz, and spaced one wavelength. Due to this separation between elements, which is limiting and not reducible by the architecture of the feeding network and the size of the radiating element, grating lobes appear. Frequency Selective Surfaces (FSS) can be a solution to this problem without modifying the feeder architecture nor the radiating elements. This paper presents the FSS design for reducing grating lobes level, the antenna assembly, and the experimental validation. The full antenna performance demonstrates that FSS operates in a range identical to the feeder (29.5 GHz to 31 GHz) with the added benefit of reducing the grating lobes level more than 10 dB for both polarizations.

“…A single-sided FSS with hexagonal periodicity, maximum transmission at 9.41 GHz (X-band) and maximum reflection at 14.5 GHz (Ku band) and 35 GHz (Ka band) is proposed in [17]. The compact packing of linear dipoles allowed for miniaturization (5 mm hexagonal cell spacing) and consequently side lobe suppression.…”

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.

“…Patch type FSS exhibits the response of a band stop filter and aperture type FSS behaves like a band pass filter when the unit cell dimension is compatible to the wavelength corresponding to the resonating frequency. Owing to its diverse merits, several researches are going on now a days to design and develop application specific FSS to fulfill its applicability in various modern applications such as electromagnetic shielding, 2 polarizers, 3 absorbers, 4 RFID, 5 cloaking, 6 radomes, 7 reduction of radar cross section 8 and satellite communication 9 . One more modern use of FSS can be noted as antenna gain augmentation when it is integrated to the antenna 10‐21 .…”

A simple structured single layered frequency selective surface (FSS) that has unit cell size of 11 × 11 mm2, substrate thickness of 0.8 mm only and capable to work in a very widespread band from 0.001 to more than 17 GHz is proposed in this article. The FSS is competent to augment the gain of a UWB monopole antenna by 2 to 3.5 dBi when integrated at the back of antenna. The performances of “antenna‐FSS” structure is evaluated by simulation and experimental measurement where good correlations are obtained. The integrated structure provides wide impedance band (S11 < −10 dB) from 2.82 to 19.94 GHz (more than 150%) with improved broadside radiation and high radiation efficiency profile. The transient and frequency domain characteristics of “antenna‐FSS” composite structure are also evaluated in close proximity of diverse sub‐surfaces such as dry sand, wet sand, wood and concrete where an almost unaltered impedance band profile, linear transfer function response and non‐varying group delay responses are achieved which establishes the applicability of the composite structure in ground penetrating radar for low depth sub‐surface scanning applications.
