Antenna Allocation in MIMO Radar with Widely Separated Antennas for Multi-Target Detection

ABSTRACT

In this paper, we explore a new resource called multi-target diversity to optimize the performance of multiple input multiple output (MIMO) radar with widely separated antennas for detecting multiple targets. In particular, we allocate antennas of the MIMO Continue reading

Precise Calibration of a GNSS Antenna Array for Adaptive Beamforming Applications

ABSTRACT

The use of global navigation satellite system (GNSS) antenna arrays for applications such as interference counter-measure, attitude determination and signal-to-noise ratio (SNR) enhancement is attracting significant attention. However, precise antenna array Continue reading

RF-to-DC Characteristics of Direct Irradiated On-Chip Gallium Arsenide Schottky Diode and Antenna for Application in Proximity Communication System

ABSTRACT

We report the RF-to-DC characteristics of the integrated AlGaAs/GaAs Schottky diode and antenna under the direct injection and irradiation condition. The conversion efficiency up to 80 % under direct injection of 1 GHz signal to the diode was achieved. It was found Continue reading

A New Metasurface Superstrate Structure for Antenna Performance Enhancement

ABSTRACT

A new metasurface superstrate structure (MSS)-loaded dual band microstrip line-fed small patch antenna is presented in this paper. The proposed antenna was designed on a ceramic-filled bioplastic sandwich substrate with a high dielectric constant. Continue reading

The Design of RFID Convey or Belt Gate Systems Using an Antenna Control Unit

ABSTRACT

This paper proposes an efficient management system utilizing a Radio Frequency Identification (RFID) antenna control unit which is moving along with the path of boxes of materials on the conveyor belt by manipulating a motor. The proposed antenna Continue reading

Microstrip Patch Antenna Assisted Compact Dual Band Planar Crossover

ABSTRACT

In Microwave Monolithic Integrated Circuits, crossovers maintain signal purity when transmission lines overlap with each other. A simple crossover for dual band applications, particularly suitable for the development of smart antennas, is presented in this Continue reading

Electromagnetic Burst Measurement System based on Low Cost UHF Dipole Antenna

ABSTRACT

Non-linear high-power devices produce electromagnetic noise (EMN) sources of great intensity that can disrupt and damage the surrounding electrical equipment and devices. This radiative phenomenon is very common at facilities where pulsed power Continue reading

Transformation from a Single Antenna to a Series Array Using Push/Pull Origami

ABSTRACT

We propose a push/pull origami antenna, transformable between a single antenna element and a three-element array. In limited space, the proposed origami antenna can work as a single antenna. When the space is not limited and a higher gain is required, Continue reading

Sea State Observation through a Three-Antenna Hybrid XT/AT InSAR Configuration: A Preliminary Study based on the InSAeS4 Airborne System

ABSTRACT

In this work, we investigate the sea surface monitoring capabilities of a Synthetic Aperture Radar (SAR) system equipped with a three-antenna hybrid Across Track (XT)/Along Track (AT) inteferometric configuration. To do this, we focus on the X-Band airborne Continue reading

A Novel Sensor based on a Single-Pixel Microwave Radiometer for Warm Object Counting: Concept Validation and IoT Perspectives

ABSTRACT

Controlled measurements by a low-cost single-pixel microwave radiometer operating at 12.65 GHz were carried out to assess the detection and counting capability for targets warmer than the surroundings. The adopted reference test targets were Continue reading

An Adaptive B-Spline Neural Network and Its Application in Terminal Sliding Mode Control for a Mobile Satcom Antenna Inertially Stabilized Platform

ABSTRACT

The mobile satcom antenna (MSA) enables a moving vehicle to communicate with a geostationary Earth orbit satellite. To realize continuous communication, the MSA should be aligned with the satellite in both sight and polarization all the time. Because of Continue reading
