Ultra-wideband is a short-range, high-bandwidth wireless technology that offers precise positioning and tracking as well as highly secure communications. It can provide accurate distance measurements in real-time without interfering with conventional narrowband and carrier wave transmissions in the same frequency bands.…

One of the indicators of innovative engineering is to take an attribute that is normally considered to be a drawback and not only negate that characteristic but actually use it to advantage in another setting. Consider this…

Although all antenna designs are derived from either the basic dipole or monopole/ground-plane configurations, there are almost countless antenna variations in use (Figure 1). Each one offers a different combination of key attributes such as center frequency, bandwidth, bandwidth, side lobes, front-to-back…
