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.
