Abstract: In this paper, a planar multiband microstrip patch antenna is presented for narrow band internet of things (NBIoT) applications. The simple planar structure covers three of the approved bands (830-840 MHz), (850-890 MHz) and (1190-1200 MHz). The return loss at resonance frequencies is less than20dB and radiation pattern is omnidirectional as desired, for all the bands. Simple basic equations of microstrip patch antenna are used for design. The simulation and performance analysis is done using HFSS tool. The design considers simple, easily available printed circuit board (PCB) with FR4 dielectric material between the patch and ground plane. Which is inexpensive, fulfills the basic need of the application. The optimetrics of the HFSS simulation tool are handy, used extensively to find appropriate feed position, optimize return loss, gain and to tune the resonance frequencies.
