Reconfigurable and Multiband Antenna Booster Element for IoT Devices with an SP4T

The increase of the IoT (Internet of Things) puts pressure
on device’s dimensions and energy costs. This is challenging
to embed an antenna into such a small device as 70 mm x 65
mm. For this purpose, a further step is taken by optimizing
the area required for the integration of a wireless
transmission system using the development of smart adaptive
networks so that a single antenna system is capable of
transmitting at different frequency bands. To validate the
procedure, a reconfigurable architecture with a single SP4T
(Single-Pole 4-Throw) operating at 698 MHz – 960 MHz and
1710 MHz – 2170 MHz is designed and built with a nonresonant
element called an antenna booster element. This
procedure opens the window to facilitate the design of tunable
antenna solutions systems for IoT designers requiring a
multiband operation.
