This paper demonstrates 300 GHz terahertz wireless communication using CMOS transmitter (TX) and receiver (RX) modules targeting sixth-generation (6G). To extend communication distance, CMOS modules with WR-3.4 waveguide interface and a high-gain antenna of 40 dBi Cassegrain antenna are designed, achieving 36 Gbps throughput at a 1m communication d...

In this paper, we present the roles played by millimeter-waves in the realization of an Internet of Things (IoT) society. Millimeter-waves are becoming essential frequency resources, enabling ultra-high-speed wireless networks supporting massive data traffic and high-resolution sensor devices. Multiple antenna technologies such as phased arrays, se...

Millimeter-wave (mmw) frequency bands, especially 60 GHz unlicensed band, are considered as a promising solution for gigabit short range wireless communication systems. IEEE standard 802.11ad, also known as WiGig, is standardized for the usage of the 60 GHz unlicensed band for wireless local area networks (WLANs). By using this mmw WLAN, multi-Gbps...

In recent times, 60 GHz millimeter wave systems have become increasingly attractive due to the escalating demand for multi-Gb/s wireless communication. Recent works have demonstrated the ability to realize a 60 GHz transceiver by means of a cost-effective CMOS process. This paper aims to give the most up-to-date status of the 60 GHz wireless transc...

In recent times, 60 GHz millimeter-wave systems have become increasingly attractive due to the escalating demand for multi-Gb/s wireless communication. The 9 GHz of unlicensed bandwidth that has been allocated at 60 GHz enables extremely high data rates as compared to those offered by 2.4 and 5 GHz wireless LAN standards. Traditionally, expensive I...

This paper presents a fully integrated transceiver chipset based on the WiGig/IEEE 802.11ad standard targeting mobile usage. The chipset is developed for single-carrier (SC) modulation, which is suitable for reduced power consumption. However, the SC modulation is sensitive to in-band amplitude variations, mainly made worse by the gain variations o...

This paper presents a newly developed arm-swinging dynamic phantom that can simulate human walking and running motions. The arm-swinging phantom has unique features, in that swinging of the right and left arms and the direction and speed of swing can be controlled independently, leading to excellent capability for replicating the variety of natural...
