Abstract
There has been a tremendous increase in demand for low-cost and compact antennas using techniques to improve their electromagnetic properties. To improve negative permittivity and negative permeability, the design and simulation of left-handed metamaterials (LHM) are used and presented. Our purpose is the betterment of return loss of antenna with the use of new incorporated LHM structure. The incorporated design has dimensions of 32 mm × 32 mm. The design has improved return loss and bandwidth while maintaining the VSWR and gain to the same level required for mobile applications as BLUETOOTH at 2.4 GHz. The proposed design is compared with conventional patch antenna which shows a significant improvement in return loss up to −41.06 dB and bandwidth 29 MHz.
