A compact pattern reconfigurable antenna with four radiation patterns is proposed for sub-GHz IoT applications. The antenna has two functional modes; Mode I has three uncorrelated patterns, while Mode II has electric and magnetic omnidirectional …
In this paper, a slot-based electronically steerable parasitic array radiator (ESPAR) antenna suitable for Internetof-Things (IoT) applications is proposed. The antenna can provide 12 directive and 2 slightly different omnidirectional radiation …
