Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Microstrip antenna design with low frequency

2018 26th Signal Processing and Communications Applications Conference (SIU), 2018
In this paper, we design patch antenna for high frequency (HF) and very high frequency (VHF). Due to size problems, patch antennas are not suitable for lower frequencies. In order to overcome these problems we try to different approach. First of all, we think a dipoi antenna for a certain frequency, in which desired microstrip antenna operate, then we ...
