O progresso tecnológico e o aumento da demanda por serviços em sistemas de
telecomunicações vêm, ao longo das últimas décadas, fomentando o desenvolvimento de …

The spectacular development of frequency selective surfaces (FSS) as a spatial filter,
absorbers and reflectors made them feasible for the aerospace and defence applications …

Monolithic integration of loading capacitors into the X-band frequency selective surfaces
(FSSs) based on ring slots is investigated as a means to control the frequency response of …

This letter introduces an energy sensitive bandpass filter (ESBPF) to protect Ku-band low
noise amplifiers (LNAs) from high power electromagnetic (HPEM) threats. The ESBPF circuit …

This research is to investigate frequency selective surface (FSS) structure effect on WLAN
application signal. The FSS structure acts as a band pass square-loop filter to attenuate the …

The demand for high gain, multi band and reconfigurable type compact antennas are
required for modern communication systems. In this paper, a unit cell design using U-shape …

Transmitarray (TA) antennas have attracted much attention in recent years due to their
number of applications. These include the 5G/6G mobile networks and satellite …

The possibility to characterize infinite and periodic frequency-selective surfaces (FSS) filters
that have two orthogonal axes of symmetry inside a waveguide is reported. Thus …

In this paper, a novel single-layer miniaturized loaded frequency selective surface (FSS)
with enhanced bandwidth operating over the GPS and DCS 1800 frequency band is …
