Driving in circles? A good GPS can help get you where you're going quickly and safely so you arrive on time.

A frequency reconfigurable phased array element is presented. The operational band of the single port L/S-band antenna can be selected by modifying the element apertures with p-i-n diode switches.

This paper presents a circular-polarized gap-waveguide-based compact monopulse array antenna for millimeter-wave tracking applications at Ka-band (29 to 31 GHz). The gap waveguide planar monopulse ...

The Semiconductor Inspection Equipment segment covers silicon wafer inspection to package finished product inspection for image sensor ICs and display driver ICs, and array inspection for display ...
