Investigation of Metamaterial Microstrip Patch Antenna for Efficient Terahertz Communication

Design of microstrip patch antenna implements the establishment of novel shaped metamaterial antenna. Over the past ten years, there has been a sharp inclination in the demand for metamaterial antennas for wireless applications. Metamaterials offer additional advantage when used in patch region. Metamaterial is used to maximize the antenna's return loss(RL), VSWR, gain, directivity and frequency. Metamaterial is also used in order to prevent unwanted sidelobes. One of the major drawbacks in conventional antenna which is surface wave effect. To resolve this metamaterial is used and also improves the gain of a patch antenna by modifying the antenna's radiation pattern. The Simulated design produces antennas gain of 4.21dBi respectively The maximum frequency of 4.04 in Terahertz and the perfect result of -42.95 dB return loss(RL). The design of meta material novel novel shape can help achieve a higher efficiency even when using the same antenna at smaller sizes.
