Efficient wideband low noise amplifier based industrial microstrip antenna design using optimization techniques

Abstract

The microwave antenna is an ever-active area of research because newlineof its never-ending demand in modern communication systems. The newlineMicrostrip Patch Antennas (MPAs) are well known because of their newlineadvantages such as low fabrication cost, lightweight, low volume and also newlinesupport both linear as well as circular polarization. On the other hand, newlineMicrostrip Patch Antennas suffer from narrow Bandwidth (BW), single newlinefrequency resonance, and large size. However, due to the advancement of newlinesophisticated technologies, the antenna designs need to be more compact and newlinethe structure should shrink to fit smaller areas. Therefore, there is an increased newlinedemand for miniaturized antennas for robust communications using newlineworldwide interoperability for microwave access (Wi-MAX), Industrial newlineScientific and Medical (ISM), Wireless Local Area Network (WLAN) bands newlinefor wireless and airborne radar systems. newlineIn this research work, a design of a miniaturized Microstrip Patch newlineAntennas is using novel optimization methods with low noise amplifiers. In newlinethe past, advances in magnetic materials such as metamaterials have opened newlinethe doors for getting enhanced performances of Microstrip Patch Antennas to newlinea large extent. This research proposes two unique approaches of Microstrip newlinePatch Antennas with improved performances for wireless and radar systems. newlineIn the first approach develop a Wideband Low Noise Amplifier newline(WLNA) with the wideband receiver. A Low Noise Amplifier radio receiver newlinefrom the mainstream is that the subsequent stages of the signal are lossless newlineand the low noise rate has the highest gain Low Noise Amplifier design is an newlineimportant task for the proper management of trade between all parameters of newlineit, including gain, noise, stability, and power consumption. newline
