Study on a Composite Patch Antenna Based on Left Handed Material with Near Zero Index
Journal Title: Elektronika - Year 2014, Vol 18, Issue 2
Abstract
In this paper, a composite patch antenna based on left handed material (LHM) with near zero index (NZI) is presented. This composite patch antenna is designed by assembling split resonant rings (SRRs) and metal strips on the substrates. This multilayer composite structure results in a metamaterial with NZI near 13.89 GHz. A method of finite difference time domain (FDTD) is used. The results show that the composite antenna’s gain improves 0.61 times, and its bandwidth adds 2.95 times compared to the conventional antenna’s ones. The results indicate that this composite patch antenna system can reduce return loss of the antenna and increase the gain obviously.
