In this paper, with the application of dielectric resonator antennas(DRA), a novel design of a shared-aperture dual-band dual-polarized (DBDP) array working in the Ka/Ku bands is proposed. At Ka-band, aperture-coupled microstrip patches are selected as the radiating elements. At Ku-band, Crossed dielectric resonator antennas(DRA) are selected as the radiating elements. The array which comprises 2×2...
In this paper, a novel microstrip antenna array with low RCS (Radar Cross Section) is presented and analyzed. Under the condition that the incident wave is in grazing angle, a single microstrip antenna which uses the techniques of miniaturization and ground-cut slots is chosen as an element of a 2×2 antenna array. Analysis and optimization of the arrangement of the array is made to realize more reduction...
In this paper, a high gain array antenna, consisting of two layers, using Giuseppe Peano Fractal Configuration as its radiation elements is designed, fabricated, and measured. This fractal array antenna consists of 8 ×8 fractal elements, is fed by a microstrip corporate feeding network, and works at frequency of X frequency band (10.0GHz). Both simulation and measurement show, the proposed fractal...
Research is done on arrays composed high gain Yagi antennas with end-fire radiation and vertical polarization. This paper mainly studies different arraying methods of the Yagi antennas and analyzes the coupling effect between array units. It includes arraying in three directions (X, Y and Z). The Yagi antenna unit is microstrip magnetic dipole antenna of which the elements are based on a new microstrip...
In this paper, using 100000 CPU cores, the parallel Finite Difference Time Domain (FDTD) algorithm based on MPI is firstly applied to analyze the radiation characteristic of a microstrip antenna array on the National Supercomputing Center in Jinan (NSCC-JN) successfully, which is a domestically-made supercomputer. And the parallel performance of the code is tested on it. The results show that the...
A GPU accelerated Method of Moments (MoM), which is run on a distributed memory CPU/GPU hybrid workstation, is presented to solve the problems of antenna array simulation. The stream technique is used to overlap the computation and data movement, and an out-of-core technique is used to break the limitation of the GPU memory. Furthermore, some microstrip antenna arrays are simulated to validate accuracy,...
The transient response of the X-band microstrip antenna array illuminated by electromagnetic pulse(EMP) was calculated using FDTD and the proposed conductor edge of singularity solving technology which maintained the high accuracy without lower computation efficiency. The research results showed that the EMP can result in the enough high response voltage in coaxial line which may destroy components...
