Abstract

A new planar multilateral bioinspired monopole antenna for Ultra-Wideband (UWB) application is proposed. Experimentally confirmed, the proposed antenna has wide impedance bandwidth, covering from 2.56 GHz to more than 11 GHz. Although the proposed antenna has a complex structure, it is easy to design and fabricate. The mathematical process, Gielis transformation, used to elaborate the symmetry is described and the design is demonstrated assuming FR4 substrate with a relative dielectric constant of 4.4 and thickness of 1.6 mm. The main electromagnetic parameters of the antenna are simulated for the UWB operation and compared with the experimental results obtained from the built prototype. Details of the results of the proposed antenna are presented and discussed.
