| Summary: | The electromagnetic beh avior of the coplanar wave- guide (CPW)-fed loaded compleme ntary split-ring resonator (CSRR) to the ultrawideband (UWB) transparent antenna is pre- sented in this letter. The transparent material known as conductive silver-coated thin fi lms (AgHT-4) is one of the unique materials that is now being implemented in antenna designs. This material has very unique advantages of very thin thickness and high trans- parency. However, it exhibits different electromagnetic properties compared to the conventional Fire Retardant-4 (FR-4) due to its surface resistivity and conductivi ty. Meanwhile, split-ring res- onators (CSRRs) are one of the metamaterial arti fi cial structures that are implemented in antenna d esign for their unique negative permittivity/permeability properties. CSRR will be designed using the transparent mat erial to achieve bandstop fi lter prop- erties centered at 5.8 GHz so as to reduce the interferences from wireless local area network (WLAN) and dedicated short-range communication (DSRC) applicatio ns. The characteristics of the SRRs/CSRRs when implemented on the high resistivity thin fi lm is compared to those implemented using copper radiating element. |
