The proliferation of the Internet of Things (IoT) has resulted in a demand for wireless connectivity to a multitude of devices. To address this need, a rapid and straightforward approach for designing multiband antenna systems utilizing antenna boosters is proposed. In this method, the antenna booster is presented as an impedance box, with a multiband matching network comprising lumped components that determine the number of frequency bands. The multiband matching network is created using a synthesizer, taking into account the measured antenna booster input impedance and simulated radiation efficiency. To validate the process, a multiband antenna system operating at 824-960 MHz and 1710-2690 MHz is implemented. The matching network has been obtained through a fully automated process, without any human intervention or adjustments, enabling the design of multiband antenna systems in a quick, easy, and systematic manner.
