ABSTRACT
In this project, High Frequency Structure Simulator (HFSS) is used to design Linearly Polarized Rectangular Microstrip Patch Antenna. The aim of the project is to design and fabricate various Microstrip Antenna using different feed techniques and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant (εr), substrate thickness on Radiation parameters of Band width. Low dielectric constant substrates are generally preferred for maximum radiation. The conducting patch can take any shape but rectangular and circular configurations are the most commonly used configuration. Other configurations are complex to analyze and require heavy numerical computations.
The length of the antenna is nearly half wavelength in the dielectric; it is a very critical parameter, which governs the resonant frequency of the antenna. In view of design, selection of the patch width and length are the major parameters along with the feed line depth. Desired Patch antenna design is initially simulated by using HFSS. And Patch antenna is realized as per design requirements.
The advantages of microstrip antennas have made them a perfect candidate for use in the wireless local area network (WLAN) applications. Though bound by certain disadvantages, microstrip patch antennas can be tailored so they can be used in the new high-speed broadband WLAN systems. This paper presents the design of rectangular patch microstrip antennas for the 2.4 GHz ISM band.
