Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to predict ...

Researchers at Cal Tech Pasadena have built an active 1.5×1.5mm near-field phased array antenna, with secure communication by spatial encryption in mind. The 61GHz radiator consists of an on-chip ...

Antenna arrays and wideband technologies are at the forefront of modern wireless communication, radar, and electronic warfare systems. Recent advances have focused on optimising beam steering, ...

The need for significant improvements in radar continues to be an ongoing concern for the Department of Defense (DoD). One of the most impressive developments addressing this need is a high-resolution ...

The operation of ground stations and phased-array antennas. How SDRs are integrated into ground stations. Issues to be considered when incorporating SDRs into phased-array antennas. Examples of ...

Until recently phased array radar has been very expensive, used only for military applications where the cost of survival weighs in the balance. With the advent of low-cost microwave devices and ...

In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...
