An Empirical Path-Loss Model for Wireless Channels in Indoor Short-Range Office Environment

open access: yesInternational Journal of Antennas and Propagation, 2012
A novel empirical path-loss model for wireless indoor short-range office environment at 4.3–7.3 GHz band is presented. The model is developed based on the experimental datum sampled in 30 office rooms in both line of sight (LOS) and non-LOS (NLOS ...

Compact Multiband Slot Antenna for WLAN/WiMAX Operations

open access: yesInternational Journal of Antennas and Propagation, 2014
A novel compact triple-band slot antenna is proposed for WLAN/WiMAX applications. With the use of three L-shaped slots and an open-ended slot on the ground plane, three resonant modes centered at 2.4/3.5/5.8 GHz are excited.

Two-Step Frequency Estimation of GNSS Signal in High-Dynamic Environment

open access: yesInternational Journal of Antennas and Propagation, 2022
To improve frequency accuracy which is affected by two parameters in high-dynamic acquisition, we propose a two-step frequency estimation method based on the mean frequency (MF) model for high-dynamic parameters estimation. The first step is based on the
