ABSTRACT: In this paper, a
numerical study is reported based on the Finite Element Method (FEM) and the Finite
Integral Technique (FIT) of Ansoft’s HFSS and CST Microwave Studio (MWS)
formulations, respectively, applied to a Bended Complementary Split-Ring
Resonator (BCSRR) of rejection band extending from 4.1 GHz to 4.6 GHz. The
proposed BCSRR structure is combined with the design of a circularly polarized
cylindrical antenna array of square patches with trimmed opposite corners. The
performance of the cylindrical antenna array is characterized and compared to
that of the flat profile. It is found that the proposed BCSRR reduces the
mutual coupling to -15 dB between two
patches with a separation of only 1/11th free-space wavelength for applications
involving Multi Input Multi Output (MIMO) system.
