Pattern reconfigurable dielectric resonator antenna using capacitor loading for internet of things applications

Abstract: This research study presents a cube dielectric resonator antenna (DRA)
with four different radiation patterns for internet of things (IoT)
applications. The various radiation patterns are determined by the grounded
capacitor loading to reduce interference. The DRA is constructed of
ceramic material with a dielectric constant of 30 and is fed via a coaxial
probe located in the antenna’s center. Capacitors are used to load the four
parasitic microstrip feed lines. Each pattern of radiation is adjustable by
adjusting the capacitors loading on the feed line. The proposed antenna
works at 3.5 GHz with -10 narrow impedance bandwidth of 74 MHz.
