Design and fabrication of high performance antennas for satellite wlan and wi fi applications

Abstract

Multiple Input Multiple Output (MIMO) antenna, Dipole array antenna, Spiral-shaped wearable button antenna, and Multiband Rectangular Patch Antenna are designed, fabricated and investigated. The above antennas operate on a single-band and multiband with improved antenna parameters. The development of wireless communications systems requires high gain, wide bandwidth and low loss antennas. The bulky metallic structure and coaxial line provide good antenna parameters, but the size of the antenna is large. newlineFor achieving high gain, wide bandwidth and low return loss in the planar antenna are challenging one. There are various existing schemes focusing on deducing the development of high gain, wide bandwidth, and low return loss. The most fascinating challenges in planar antennas consist of large size, narrow bandwidth, losses, and degradation in antennaand#8223;s radiation characteristics and complexity. The high performance antennas provide low loss, high gain, bandwidth and less mutual coupling, small in size. The simulated results are proven with high performance antennas and are analyzed. newlineIn this concise presentation, five different antennas namely Cross dipole antenna, Multiple Input Multiple Output (MIMO) antenna, Dipole array antenna, Spiral-shaped wearable button antenna, and Multiband Rectangular Patch Antenna are designed and fabricated. By this high performance antennas, multiband, wideband, high gain, low mutual coupling are achieved. The designed work is divided into five main phases. The first phase aims to Design and Development of Cross Dipole Antenna for Satellite Applications and to improve the gain. newline
