摘要

This paper aims at a new planar left hand metamaterial structure for loading planar microstrip antenna (MPA). A metallic planar dual turn spiral resonator (DTSR), useful for artificial magnetic media design, is merged with a capacitive loaded strip (CLS) on the same plane to design capacitive strip coupled spiral resonator (CSC-SR) unit cell structure. Apart from having small size, the new structure offers advantages of demonstrating wide left handed frequency band, and simplicity of fabrication being on same plane, hence indicating supremacy of its inclusion in engineering of left hand metamaterials. The size of proposed antenna is 0.177 lambda x 0.243 lambda. The electro-magnetic coupling of the proposed structure causes the MPA to resonate at lower frequency of 13.25 GHz due to loading effects. The proposed novel antenna is able to give better performance in terms of return loss, gain and fractional bandwidth and is suitable for satellite communication. The measured results are presented to validate simulated model of the proposed antenna.
