Generation of dual‐mode PS‐OAM beams using a Vivaldi antenna array

open access: yesMicro & Nano Letters
The paper proposes a single antenna that can generate dual‐mode plane spiral orbital angular momentum (PS‐OAM) beams. Six Vivaldi antennas placed in a tangential circular array make up the antenna, and the antenna is etched onto a substrate material and ...

Flexible Wideband Microstrip-Slotline-Microstrip Power Divider and its Application to Antenna Array

open access: yesIEEE Access, 2019
In the satellite microwave power transmission (MPT) system, antenna arrays are usually adopted for a higher gain. For the passive wideband antenna array, wideband power dividers are essential when the feed network is constructed.

Feeding‐line‐based decoupling patch antennas

open access: yesIET Microwaves, Antennas & Propagation
Mutual coupling among multiple antennas has been a problem needed to be tackled in multiple‐input‐multiple‐output (MIMO) systems. A decoupling method based on short decoupling feeding lines (DFLs) for MIMO patch antennas is proposed.
