Effect of CSRR rotation on size and polarization of antenna

This paper describes the design and development of microstrip patch antenna with circular metamaterial structure at the ground plane that will be rotated multiple times at an incremental angle of 22.5°. There are several benefits that result from the introduction of the metamaterial structure rotated to various angles to the patch antenna such as increased number of frequencies, increased efficiency and gain at lower frequencies, reduced size antenna, and changed polarization. The antenna is also horizontally polarized at lower frequencies with high gain and efficiency when the metamaterial structure is rotated to 22.5° and 45° while operational at only one lower frequency for 67.5°. These responses are confirmed through the standard antenna measurement process.
