On the Path Loss Model for 5-GHz Microwave-Based Pinless Subsea Connectors

Published in: Progress In Electromagnetics Research

Jun 01, 2019

Jose Carlos Reyes Guerrero Ismail Ben Mabrouk Muath Alhassan Mourad Nedil

In this work, a simple propagation channel model for microwave-based pinless subsea connectors in the 5 GHz band is presented. Both high electromagnetic attenuation in seawater due to absorption and the near-field working conditions typically present for underwater connectors are taken into consideration. Therefore, a simplified path loss model based on linear regression is identified. The study shows that high-speed pinless subsea connectors are a reality over several cm of seawater gap when appropriate microwave receiver technology is selected with sensitivities of about-100 dBm. Experimental results show that both half-duplex gigabits-per-second and full-duplex 100-Mbps technologies have a strong potential to be developed in the 5 GHz band.

Hybrid Isolator for Mutual-Coupling Reduction in Millimeter-Wave MIMO Antenna Systems

A novel millimeter-wave hybrid isolator is presented to reduce the mutual-coupling (MC) between two closely-spaced dielectric resonator (DR) antennas at 60 GHz. The proposed hybrid isolator consists of a combination of a new uni-planar compact electromagnetic band-gap (EBG) structure and a Millimeter-wave (MMW) choke absorber. The design of the proposed EBG unit-cell is based on the stepped-impedance resonator (SIR) technique. Results show that the proposed EBG structure provides a wide frequency bandgap in the 60 GHz band with miniaturization factors of 0.79 and 0.66 compared to conventional uni-planar EBG and uni-planar compact (UC-EBG) structures, respectively. The proposed EBG is then placed between two Multiple Input Multiple Output (MIMO) DR antennas to reduce the MC level. As a result, an average of 7 dB level reduction is obtained. To further reduce the MC level, a thin MMW choke absorber wall is mounted vertically between the two DR antennas and above the EBG structure. An average of 22 dB MC reduction is achieved over the suggested bandwidth while maintaining good radiation characteristics. The measured isolation of the prototype antenna varies from –29 to –49 dB in the frequency range from 59.3 GHz to 64.8 GHz. In fact, the proposed hybrid isolator outperforms other hybrid isolation techniques reported in the literature.

Experimental Validation of Receiver Sensitivity for 100-Mbps Data Rates in Seawater by Using 2.4 GHz-Low-Power Electronics

This paper presents an experimental validation of the receiver sensitivity for 100- Mbps microwave data communications in a typical subsea environment. It is demonstrated that underwater microwave-based pinless connector solutions can perform under conditions that have not been explored until now. Traditional “pinned” subsea wet-mate connectors require precise rotational and angular alignment to achieve efficient and reliable connections. The demonstrated flexibility offered by pinless connection shows clear operational and reliability advantages. In this study, experimental works are based on a simple loop antenna fabricated on PCB FR4 substrate under typical subsea boundary conditions. Measurement results show that high data throughputs of 100 Mbps are achieved at 2.4 GHz with a receiver sensitivity of -60 dBm, using optimized regular antennas. In addition, maximum data throughputs are attained for seawater gaps of about 40 mm

High gain dielectric resonator antenna with soft cavity and soft surface for millimeter-wave applications

Published in: International Journal of Mechanical Engineering and Technology

Dec 01, 2018

/ muath alhasan

In this paper, a 60 GHz high-gain dielectric resonator antenna (DRA), integrated with soft surface and capacitive soft cavity is presented. The soft surface consists of a perforated dielectric cylinder, shorting vias, and three concentric layers of metallic strips printed on both sides of the dielectric cylinder. The capacitive soft cavity comprises ten concentric planar strips printed on top of a dielectric substrate. The soft surface blocks surface wave propagation by introducing a gap waveguide, while the soft cavity focuses the beam in the main direction yielding more directive power pattern. When incorporating the soft cavity and the capacitive soft surface with the aperture-coupled DRA, simulation results show a gain increase of up to 3 dB, front-to-back ratio enhancement of 7 dB, and less radiation toward the substrate edges.

Millimeter-Wave Compact EBG Structure for Mutual Coupling Reduction Applications

A new millimeter-wave (MMW), electromagnetic band-gap (EBG) structure is presented. The proposed EBG structure without the use of metallic vias or vertical components is formed by etching two slots and adding two connecting bridges to a conventional uniplanar EBG unit-cell. The transmission characteristics of the proposed EBG structure are measured. Results show that the proposed EBG structure has a wide bandgap around the 60 GHz band. The size of the proposed EBG unit-cell is 78% less than a conventional uniplanar EBG, and 72% less than a uniplanar-compact EBG (UC-EBG) operating at the same frequency band. Moreover, and despite the fabrication limitations at the 60 GHz band, the proposed EBG unit-cell provides at least 12% more size reduction than any other planar EBG structures at microwave frequencies. Its enhanced performance and applicability to reduce mutual coupling in antenna arrays are then investigated. Results show a drastic decrease in the mutual coupling level. This EBG structure can find its applications in MMW wireless communication systems.

Design, fabrication and testing of millimeter-wave (MMW) dielectric resonator antenna (DRA) surrounded by electromagnetic band-gap (EBG) structure are presented. For this purpose, MMW mushroom-like, circular patch EBG (CP-EBG) cell is designed and fabricated. The propagation characteristics of the proposed CP-EBG structure are measured using the asymmetric microstrip line method. A cylindrical DRA incorporating the developed CP-EBG structure is then designed and its performance is evaluated with and without the CP-EBG around the 60 GHz bandwidth. Measurements show a significant improvement in the antenna radiation characteristics when it is surrounded by CP-EBG structure. A gain increase of up to 3.2 dBi is obtained while preserving the gain flatness over the suggested bandwidth ( ± 0.7 dB). An additional backlobe suppression of up to 6.5 dBi is achieved. Moreover, radiation toward substrate edges is significantly reduced.
