Development of Antenna Receiver Subsystem

Abstract

This final year project will design Antenna Receiver Subsystems (ARS) that operate at the 2.45 Ghz of frequency. The ARS is includes four major components such as Low Noise Amplifier (LNA), Mixer, Band Pass Filter and Radio Frequency (RF) Amplifier also the antenna itself. This antenna project also were design in order to increased the ability of the application that is involved through the usage of this system such as the wireless LAN communication or in RF communication as it main objectives where the antenna subsystem is design based on some certain circuit’s concept where hopefully it can increased the ability of receiving signal in wireless communication and the application field that had been mentioned before. In order to achieve the goal, four elements that had been mentioned before shall be improved from a certain steps. First of all, the four elements will be design using Microwave Office and the OrCad Capture CIS as simulation can be done using these software. After completing design the four elements using the software, the elements were then fabricated and tested for its characteristics with antenna. It is expected that several measurement and reading can be take from this project in order to make a comparison between antennas with it receiver subsystem and without its subsystem. Some characteristics that will be measured are such as output waveform and measurement reading.
