Study of an UWB Spherical Monopole Antenna on the Dielectric Substrate

Seyed Ehsan Hosseini and Mostafa Attaran Kakhki
Abstract—A spherical monopole antenna on the dielectric substrate is proposed for UWB applications. The antenna uses a combination of the conductor spherical antenna, the dielectric substrate and the ground plane under substrate. The simulated results demonstrate that the design structure covers the frequency range 4.6 GHz-10.6 GHz and more. The radius of sphere and the height of the antenna is R=5 mm, h=3.2 mm, respectively. In this paper, the effects of varying the dielectric constant, the radius of spherical, and the height are investigated. Good radiations are obtained over the wide bandwidth with an acceptable gain. Also, the input impedance of the proposed antenna is simulated by HFSS and demonstrated. Details of design structure are presented and studied.

Index Terms—Spherical antennas, monopole antennas, UWB.
