A novel slot array is proposed for uses on femtocells of mobile services. The array contains multiple sets of equally spaced slots connected in series on a coplanar waveguide. A diode-loaded shorting strip is mounted across each slot to enable or disable radiation so that switchable beams of different tilting angles can be provided. The proposed design comes as a flat panel hanging on the wall. The...
This work proposes a real-time and low cost direction-of-arrival (DOA) estimation measure. The system is based on a Rotman lens to simultaneously detect signals from a broad angular sector. Lens beam ports are connected to low cost power detectors. Received power levels are then fetched by a multi-channel data acquisition card to form a reception signal vector. The vector is then normalized and compared...
The introduction of Internet of things (IoT), to a certain degree, redefines the scope of wireless communication. As the concept of pervasive computation becomes reality, compact devices, which are capable of sensing and relaying data, are in great needs. This work present a dual-antenna configuration for compact platforms. The projected protocol is wireless local area network (WLAN). Diversity antennas...
