UWB technology has strengths such as anti-interference, high-speed transmission, high security, and low power consumption. Additionally, the frequency of UWB is higher and the wavelength is shorter. So, it is suitable for the indoor positioning era. In Unictron’s cases, the UWB chip antenna is used in smart homes and keyless entry for automobiles. These three chip antennas are the UWB chip antennas that Unictron provided.
