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 non-resonant 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.
