A Folded Miniaturized Antenna for IoT Devices

Abstract

In this paper, a new miniaturized folded patch antenna design is presented and proposed for IoT devices' implementation. The antenna is designed to operate at the ISM band (805-835MHz). The miniaturized design achieves a 95 % size reduction after resorting to different size reduction techniques. These techniques include folding, slots and slits in addition to inductive loading using vias. The antenna is fabricated and measured where measurements show good agreement with the simulated data.
