Numerical and Experimental Analysis of CSRR Structures in Bioinspired Microstrip Antenna

Abstract

The growing use metamaterial structures have the aim to improving radiating systems and microwave devices. Split Ring Resonator (SRR) and Complementary Split Ring Resonator (CSRR) are examples of such structures. In this paper, CSSRs have been used in the ground plane of a bioinspired microstrip antenna, designed for the 5.8 GHz band, in order to provide an improvement of its fundamental parameters and possible miniaturization of this device. For the antenna design, the Gielis’ superformula has been used, generating a bioinspired form in the anemone (flower). Thus, numerical and experimental analyzes have been performed, always observing the changes caused by the insertion of CSRRs, mainly observing a control of band and retreat in the resonance frequency, allowing the process of miniaturization.. Numerical results have been obtained using the ANSYS commercial software, which uses the Method of Moments (MoM).
