In this paper, a miniature improved gain Circular Patch Antenna (CPA) is reported. An array of Circular Split Ring Resonators (CSRRs) is loaded into a circular patch to transfigure the surface current distributions leading to miniaturization and significant gain enhancement. To obtain a bi-conical beam, the antenna is operated at Higher Order Mode (HOM). The HOM is excited by suitably selecting the feeding location. The unit cell of the CSRR is analyzed and the permittivity of the CSRRs loaded antenna structure is extracted using Scattering Parameter Inversion (SPI) method. The proposed antenna operates in 5.2 GHz band and built on a thin (0.254 mm) RT/Duroid 5880 substrate thus, flexible in nature. The bending analysis is performed showing a natural frequency shift. To validate the proposed design, the prototype is fabricated showing good agreement amongst simulated and measured results is found. [ABSTRACT FROM AUTHOR] |
