Design and Simulation of Microstrip Antenna Using Composite Right/Left Handed Transmission Line (CRLH-TL) Technique for LTE and Radar Applications

A compact metamaterial inspired antenna operates at LTE and Radar applications is introduced in this paper. Control and manipulation of electromagnetic waves is at the heart of many industries from wireless communication, internet and optical data storage to imaging and displays. Progress in these technologies places challenging demands on material properties and therefore structured electromagnetic materials. Metamaterials are a special class of structured materials. Patterning on the sub-wavelength scale allows precise engineering of their electromagnetic properties over a range going far beyond natural media. In this paper, microstrip antenna consists of radiating patch and two parasitic elements (open-loop ring resonators) to serve coupling bridges with partial ground plane and composite right / left-handed transmission line (CRLH-TL) embedded in the patch antenna. The antenna topology possesses an area 26×37×1.27 mm

. The analysis and design is simulated and optimized commercial software. The good agreement between the theoretical expectation and the simulation results is observed. Finally, the proposed optimum antenna design structure has been fabricated and the measured S-parameters, VSWR of the proposed structure can be analyzed with network analyzer to demonstrate the excellent performance and meet the requirements for LTE and Radar applications.
