Fringing Field In Microstrip Patch Antenna Projects For Beginners

1. Types, specifically microstrip patch, dipole and helical, which can then be expanded to. Antenna designs were performed using RF modeling software. The fringing fields about the two slots of the patch antenna makes the microstrip line.
2. This project brings to the extended list of research analysis on microstrip patch. Because of fringing fields, the patch behaves as if it has a slightly larger.

Antenna-Theory.com - Transient Fields Under a Microstrip Antenna Microstrip Antenna - Transient Fields (the Movie)On this page, I will present a movie showing the fields under a microstrip antenna. In this numerical experiment,a short pulse will be launched from the end of a microstrip, which will travel towards the patch antenna. Some ofthe pulse will radiate away, and some of the power will be reflected back down the microstrip line. Thistype of simulation gives a little bit better idea of what is going on with a patch antenna, specifically whenshort pulses (short waveforms, or brief applied voltages) are incident upon a microstrip antenna.Specifically, consider a patch antenna that is mounted on a ground plane, with a dielectricwith equal to 2.2. The thickness of this dielectric is 0.795 mm (millimeters).The patch antenna will be 1.25 centimeters wide and 1.56 centimeters long (you should be able to tellwhat frequency this antenna will radiate well at - if not, seepage).The microstrip antenna will feed the patch offset from the center, as shown in Figure 1.Figure 1. Offset feed for Patch Antenna.The transient pulse will be of the form given by exp(-(t-T0)/T )^2, whereT0 is the time delay and will be 45 pS (picoseconds, 10^-12), and T is a parameter that controlsthe rate of rise and fall, which is 15 pS.

This function is plotted in Figure 2.Figure 2. Damone roll the dice megaupload shut down song. Incident (transient) pulse fed to a Patch Antenna.In the following video, we will view the z-directed electric field, immediately below the patch antenna.Note that the surface of the patch is normal to the z-axis. We can clearly see the incident pulse propagatedown the microstrip line, be disturbed by the microstrip antenna, then some of the fields are reflected, someradiate away, and some stay resonant below the patch and eventually radiate away or reflect back down themicrostrip line.Patch AntennasA simulation of a patch antenna fields are shown; particularly a broadband Gaussian pulse on a square microstrip or patch antenna is shown.This video shows a Gaussian pulse travel down the microstrip. Some energy is reflected back. Incidentally,taking the Fourier transform of the incident pulse and the returned signal and taking the ratio wouldgiveas a function of frequency for this antenna.If you would like to see how this numerical electromagnetics simulation was developed, see thepage.
