A multiband truncated patch antenna based on EBG structure for IoMT and 5G networks
In this paper, a truncated patch antenna based on the electromagnetic band gap (EBG) structure has been proposed. The fabricated antenna has five operating frequencies at 10.4, 15.68, 19.68, 27.2, and 35.04 GHz. The fabricated prototype of the antenna constitutes a truncated rectangular patch etched with the shape of a symmetrical slot (on top) and an EBG loaded on the ground plane of the dielectr
Highly selective, fractal-configured UWB-FSS for sub-6 GHz 5G, GSM, WLAN, and C band electromagnetic stealth application
A miniaturized and flexible frequency-selective surface (FSS) has been presented in this article with a unit cell size of 0.049 × 0.049 where is the free space wavelength at the lower cut-off frequency. In order to achieve an ultra-wide (?3 dB) second order pass band of 151.3% with enhanced selectivity factor of 0.887, a cascaded triple layered hybrid resonating structure has been proposed with
Computer simulation, visualization, and synthesis of a digital antenna array used for transmitting and receiving signals in industrial applications
The article is devoted to computer modeling, visualization, and synthesis of a digital antenna array used for transmitting and receiving signals in industrial applications. The paper proposes an iterative method for the amplitude-phase synthesis of an antenna array according to the requirements for the envelope of the side lobes. The proposed method allows to determine the complex amplitudes of th

Highly miniaturized wideband angular stable linear?circular and linear?cross polarization converter for Ka-band satellite applications
This work proposes a novel, extremely miniaturized wideband linear?circular and linear?cross metasurface-enabled reflective polarizer. This design comprises a Meander-line structure with horizontal dipoles as the top frequency selective surface, printed on a 1 mm thin-grounded FR-4 substrate. The /-polarized incident electromagnetic wave is converted as circularly polarized from 10.60 to 10.92 GHz
A super-heterodyne passive 35 GHz millimeter-wave imaging system for detecting hidden objects
Passive millimeter-wave imaging systems (PMWIS) are employed for detecting concealed objects by mapping millimeter waves emitted from materials or living tissues. The emitted waves are measured by a receiver or radiometers without employing external wave sources. In this paper, a new super-heterodyne receiver front-end of a PMWIS at 35 GHz with an even order band pass filter is simulated and imple
Countering self-protection interrupted sampling repeater jammer against chirp radar
Interrupted sampling repeater jammer generates multiple false targets to confuse chirp radar systems. In practical situations, maintaining separation between true target echo and jamming signal is not possible because the jamming pulses and the true target echo are overlapping in both time and frequency domains. A new anti-jamming technique against interrupted sampling jamming of self-protection r
