Band switching/aperture tuning technology is the ideal solution when
the environment is reducing the original antenna bandwidth.

IoT devices tend to have small size, and therefore the performance (bandwidth/efficiency) of embedded antennas can be strongly degraded. By using an active antenna solution such as band switching/aperture tuning, it is possible to cover a wider frequency range by actively switching bands. For the same number frequency bands to be covered, the active antenna will have a smaller size compared to the passive antenna. At equal size, the active antenna will cover more frequency bands than the passive antenna.

Using a shunt KYOCERA AVX EC646 RF switch will accommodate the antenna frequency response to shift to the lower or higher frequency, based on pre-defined matching circuit values. The chip provides a broader global band coverage with a single antenna element. It achieves this by using parasitic loading and active tuning techniques, especially to meet the stringent low band antenna efficiency requirements.
