Abstract

In this paper, the design of an Ultra Wide Band (UWB) hemispherical antenna with Log-Periodic Elements (LPEs) capable of operating at multiple resonating frequencies lying in L, S, C, X, and Ku frequency bands is presented. The design consists of a complex structure of silver hemisphere with LPE mounted on an FR-4 substrate fed by a 50 Ω microstrip line. The dependency of the inclination of log-periodic elements mounted on the hemisphere is analyzed with parametric study. The proposed miniaturized antenna uses LPEs to obtain an impedance bandwidth of above 100% and a multi-directional radiation pattern. The measured results show that a wide operating band of 12.63 GHz (1.68 GHz-14.31 GHz) (8.52:1) has been achieved with a multi-directional radiation pattern with a peak realized gain of 8.12 dBi.
