This paper presents the 300 GHz path loss measurements on a computer motherboard. In the measurement campaign, three different scenarios have been considered: a line-of-sight (LoS) scenario in the presence of a large ground plane (i.e. motherboard), a LoS scenario where the transmitter (Tx) and receiver (Rx) have different heights such as a link between the processor and memory, and an obstructed...
This paper presents a preliminary study of channel characteristics in the frequency ranges of 75 – 110 GHz and 270 – 320 GHz. We select a small office as a typical application scenario and carried out extensive measurements with the Vector Network Analyzer (VNA) and frequency extension units in the room. A ray tracing simulator is applied for reproduction of the measurement results and a good match...
In this paper, a miniature UHF-band Zigbee antenna is proposed. Considering a lighter weight and smaller footprint of the Zigbee platform attached to a walking person, the antenna is meandered on the top and partially short circuited on the bottom, and optimized with non-uniform widths and lengths of the radiating element, and capillary paths. Due to these contributing factors, the physical area is...
A wireless-powered pad-less single-chip dual-band mm-wave passive radio is implemented in 65nm CMOS for applications in sensor networks and wireless tagging. This fully self-sufficient system has no pads or external components (e.g. power supply), and the entire radio is a single 3.7mm × 1.2mm chip. To provide multi-access, and to mitigate interference, it uses two separate mm-wave bands for RX/TX...
High-speed and energy-efficient wireless communication using the 60GHz band is attracting attention, and recent works have realized a highly integrated CMOS transceiver (TRX) [1–2]. This paper presents a fully integrated chipset for short-range/one-to-one wireless communication. The chipset is composed of 2 chips, an RF chip with in-package antenna and a BB chip including PHY/MAC layer. The chipset...
