Enhanced Performance of Metamaterials Loaded Substrate Integrated Waveguide Antenna For Multiband Application

The investigation of the design and analysis of a Metamaterials loaded Substrate Integrated Waveguide (SIW) antenna for Multiband Applications. A ground arrangement through a radiating rectangular patch conflicting the feed line as well as a mixture of Substrate Integrated Waveguide and Metamaterials is presented for the proposed antenna. These are utilized to improve the antenna's bandwidth and Radiation pattern while also reducing its size. To improve directivity, gain, and bandwidth, a complementary square split ring resonator and Substrate Integrated Waveguide are utilized. The proposed antenna structure is made of FR-4 epoxy with a ε
r
=4.4. The antenna functions over the frequency range of 6-18 GHz, with a resonant frequency for Wireless LAN and WIMAX.
