Abstract

Objectives: The aim is to design a Microstrip Patch Antenna (MSA) for enhancement of bandwidth and improved outcome for return loss. The approach for dimension decrease is also a parameter for designing of this antenna. Method: A shorted pin, coaxial feed, Microstrip Patch Antenna (MSA) is used for wireless communication. The patch with U type slot, cut at corner and also shorted by shorting pin is the design of an antenna. For good efficiency proposed antenna’s design parameters are optimized by HFSS’s Optometric. Findings: The proposed antenna has a wide band frequency ranged from 1.4 GHz to 4 GHz with Bandwidth of 210 MHz and 250 MHz return loss of-11.45db and -20.50dB respectively. In this design HFSS (High Frequency Structure Simulator) software is used which is a FEM based electromagnetic solver. The parameteric analysis of return loss, gain and bandwidth is done in an extended form in the proposed antenna design. Application: This design is suitable for the function in wireless communication system and also for fabrication proposes design is very simple.

Abstract

Objectives: This paper represents the design and simulation of LNA (Low Noise Amplifier) for ISM (Industrial, Scientific and Medical) applications operating in the 2.4-2.5 GHz band. Methods/Statistical Analysis: In this paper, a very accurate topology named inductive source degeneration topology has been used to provide low NF (Noise Figure), high S21 (forward gain) and very low Power Consumption (PC). The simulation was made through using Advance Design System (ADS) software. Findings: The proposed work prominence on reduction in Noise Figure with increase in power gain at low power consumption as compared to published previous results at 1.2 V power supply. Improvements: This is done in three steps (three different schematic designs) i.e. start with very basic LNA design to proposed LNA design and presents the comparison of all three designed circuit simulations.
