VSWR & Reflected Power. In telecommunication, a microstrip antenna (also known as a printed antenna) usually means an antenna fabricated using photolithographic techniques on a printed circuit board (PCB). The microstrip patch antenna can also be designed using an artificial neural network (ANN) modeling technique where size of the antenna is major limitation especially in mobile and wireless applications. Microstrip antennae are very simple in construction using a conventional microstrip fabrication technique.

Although the microstrip antenna has been extensively studied in the past few decades as one of the standard planar antennas, it still has a huge potential for further developments. In some instances the anisotropy is a principal feature of the design materials, as is the case with biased ferrite substrates. antenna temperature is often preferred when passive sensors for radio astronomy or remote sensing are of interest. This tool is designed to calculate the correct dimensions of a microstrip patch antenna if the operating frequency and the dielectric constant of the material used, is known. 3 0 obj <> The Microstrip Antenna (MSA) that we have designed can work on an ultra-wide band. For a transmitter antenna, antenna’s input impedance should match with transmitter amplifier’s output impedance, along with the transmission line impedance. o Used for very high gain applications with added advantage, such as, controllable radiation pattern. This video is unavailable. In software simulations, there is one parameter called axial ratio through which the type of polarization is iden-tified. Antenna Effective length is used to determine the polarization efficiency of the antenna. Write short note on i. Biconical antenna. 4 0 obj endobj If the dielectric constant of the material is not known, you can choose to put in the velocity of propagation of the signal instead. Chapter 14 in Antenna Theory, Analysis and Design (4th Edition) by Balanis 14.4 Quality Factor, Bandwidth, & Efficiency The frequency chosen for the microstrip antenna is 2.4GHz7 and it has been chosen from IEEE 802.11 which is for the Wireless Fidelity (WiFi) network. In this chapter, analysis and synthesis problems for designing of microstrip patch antennas were discussed using the artificial neural network technique. This project is divided into three major parts which are calculation, simulation and hardware design. Copyright © 1967 ACADEMIC PRESS INC. Microstrip antenna elements have a number of useful and interesting features, but probably the most serious limitation of this technology is the narrow bandwidth of the basic microstrip element. It plays a very significant role in today’s world of wireless communication systems. It is clearly much easier to construct than a shielded strip line but it suffers the disadvantages DIELECTRIC r L FIG. 1 0 obj Log periodic antenna having bandwidth ratio of 5, k=1.2 and α=15 is to be designed. <>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> microstrip_ant2.doc Page 1 of 5 Microstrip Antennas cont. It is a kind of internal antenna. Diplexer. An artiflcial neural network (ANN) is used here for reducing some of these problems. Microstrip antenna model for an elliptical polarization is dis-cussed in [25]. Book Abstract: "This anthology combines 15 years of microstrip antenna technology research into one significant volume and includes a special introductory tutorial by the co-editors. stream The antenna was placed at a height of 120 cm. ANNs are computational tools that learn from experience (training), which provide fast and accurate models for microwave modeling, simulation, and optimization. %���� The paper suggests three areas for further research based on our previous works on microstrip antenna elements and arrays.
