A Wideband Highly Efficient Omnidirectional Compact Antenna for WiMAX/Lower 5G Communications
(Wiley, 2023)
Microstrip patch antenna (MPA) is widely used for different wireless communications such as WiMAX and fifth generation (5G). In this paper, a wideband, highly efficient, omnidirectional, compact novel patch antenna has ...
Phase (1T/2H) dependent electromagnetic wave absorbing performance of flower-like MoS2 nanosheets
(Elsevier, 2023)
A study was carried out to determine the phase-dependent electromagnetic wave (EMW) absorption performance of MoS2 particles via systematically diversified hydrothermal synthesis conditions such as time, temperature, ...
Pattern Shaping by Utilizing EBG Phase Response and Its Use in MIMO Radio Altimeter Antenna Design for Aircraft
(MDPI, 2023)
In this study, a novel pattern shaping technique is presented and applied to the uniquely designed multiple-input multiple-output (MIMO) radio altimeter antenna, acquiring area gain. Inspired by the behavior of the perfect ...
Prevention of Wave Propagation via Circular Arrangement of Seismic Metamaterials Formed with Concrete Piles
(MDPI, 2023)
It is known that the low frequencies of seismic surface waves have a destructive effect. The main purpose of seismic metamaterials is to protect structures from seismic waves at low frequencies, especially in a wide band. ...
Design and Characterization of a Compact Four-Element Microstrip Array Antenna for WiFi-5/6 Routers
(Wiley, 2023)
The WiFi-5 band was the most popular WiFi band until the Federal Communications Commission (FCC) announced a new spectrum of 6 GHz WiFi (5.925-7.125 GHz) for unlicensed users. Our proposed work is about to cover both the ...
Görüntü İşleme Yoluyla Otonom Tren-Hayvan Kazası Önleme Sistemi
(Demiryolu Mühendisleri Derneği, 2023)
Çalışmada tren yolu ulaşımlarında yol güzergâhı üzerinde bulunan hayvan ölümlerinin önlenmesi üzerine odak sağlanmıştır. Hemzemin geçitlerde bulunan bariyer sistemleri raylı ulaşım araçlarının çarpışma kazalarını önleyici ...
Detection of Toxic Gases Using Flexible Metamaterial Absorber at Terahertz Frequencies
(Osmaniye Korkut Ata Üniversitesi, 2023)
The development of technology implies the release of several gases to the environment. These gases, especially toxic ones, have many negative effects on human life and cause many diseases that will adversely affect human ...
Direct Analysis of Chlorine Ionized Cement-Based Composites and Its Sensor Application By 2,5GHz Antennas
(Osmaniye Korkut Ata Üniversitesi, 2023)
In this paper, we propose a system that discriminate cement-based composite including sea sand by using microwave patch antennas. The composites with sea sand have vital importance in construction engineering industry ...
Utilization of toxic marine invaders in the development of low-loss microwave devices
(Niğde Ömer Halisdemir Üniversitesi, 2023)
This research paper presents constitutive parameters of toxic marine invaders (Diadema setosum) and offers the availability of materials from these invaders for microwave applications. Two different powder form of these ...
Microwave Imaging Approach for Breast Cancer Detection Using a Tapered Slot Antenna Loaded with Parasitic Components
(MDPI, 2023)
In this paper, a wideband antenna is proposed for ultra-wideband microwave imaging applications. The antenna is comprised of a tapered slot ground, a rectangular slotted patch and four star-shaped parasitic components. The ...
