Novel Compact Hybrid Monopole ASA Antenna

This paper presents a novel compact, wideband, four directional radiation patterns, antenna. The radiating element topology is inspired from the Annular Slot Antenna (ASA) and printed wideband monopole. The antenna is designed for North American ATSC-TV indoor reception. For an S11<;-6dB, it covers both High-VHF and UHF bands. It presents four relatively uncorre…

In this paper, we propose a novel approach for real-time radar-based human activities detection and classification. In this approach, first, the radar transceiver is mounted on the room’s ceiling leading to considerable variations of the relative received power as the subject perform the different activities. Second, to exploit the different activities’ dynamics…
