In this paper, an E-shaped microstrip patch antenna is presented for internet of things (IoT) applications via Bluetooth
communication. The visionary flattened structure designed to operate at 2.4 GHz. For this band, radiation, pattern is
omnidirectional and the return loss at resonance frequencies is less than -10dB. Mathematical equations of microstrip patch
antenna are used for design. The HFSS simulation tool are handy, used extensively to find appropriate feed position, optimize
return loss, gain and to tune the resonance frequencies. The simulation and performance analysis is done using HFSS tool. The
design considers simple, easily available printed circuit board (PCB) with RT/Duriod 5880 dielectric material between the patch
and ground plane, which is inexpensive, fulfills the basic need of the application.
