A Compact CPW-Fed Ultra-Wideband Multi-Input-Multi-Output (MIMO) Antenna for Wireless Communication Networks

IEEE Access, 2022
In this article, a compact coplanar waveguide (CPW) technique based ultra-wideband multiple-input-multiple-output (MIMO) antenna is proposed. The design is characterized by a broad impedance bandwidth starting from 3 GHz to 11 GHz.

Dispersion engineering of W2 steeple-house-defect waveguide photonic crystal

Results in Physics, 2020
An epitome for dispersion and buffering in a photonic crystal was set forth. Slots in the form of a line of contacted steeple-houses are implanted in a two-line photonic crystal waveguide (2LPCW) to form an irregular slot of steeple-house defect PCW ...

Research on the Ionospheric Delay of Long-Range Short-Wave Propagation Based on a Regression Analysis

Remote Sensing
The ionospheric delay effect is inevitable when a radio signal propagates through the ionosphere. It has been extensively studied in the L-band. Typically, the influence of the ionosphere on the code phase and carrier phase is regarded as the same.
