Sensitivity Analysis for Antenna Using Monte-Carlo Simulation

A workflow for the sensitivity analysis of microstrip patch antenna gain using the design space sampling. You explore the design of a microstrip patch antenna to study the sensitivity with respect to different design parameters of the antenna. The design includes uncertainty for the patch and ground plane width. You explore the rectangular microstrip patch antenna design by characterizing design parameters using probability distributions. Generate the values of the patch width and ground plane width from random samples of the distribution functions and perform Monte-Carlo simulation of the design at each of the sample data points. You then visualize the design space to select the best design. Using the sampled design space, you perform Monte-Carlo evaluation and use the result to analyze the influence of design parameters on the design.

Polarization Analysis of X-band Microstrip Patch Antenna

Perform polarization analysis on a microstrip patch antenna with the air substrate. The dimensions of this antenna are referenced from [1] for the center frequency of 10.35 GHz. In most basic form, a microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate and a ground plane on the other side. Microstrip patch antennas radiate primarily as wide open-open half-wave microstrip resonators. The length L of the rectangular patch for the fundamental excitation mode is slightly less than λ/2. For a good antenna performance, a thick dielectric substrate having a low dielectric constant is usually desired since it provides a larger bandwidth and a well-defined beam. A rectangular microstrip patch antenna normally radiates a linearly polarized wave with about 6-7 dBi gain at broadside. Higher gains (up to 10 dBi) can be achieved by using different means including large patch heights and parasitic patches.

Analysis of Inset-Feed Patch Antenna on Dielectric Substrate

Showcases the analysis of an inset-feed patch antenna on a low-epsilon, low-loss, thin dielectric substrate. The results are compared with the reflection coefficient and surface currents around the 2.4 GHz, Wi-Fi band for a reference design [1]. The Antenna Toolbox™ library of antenna elements includes a patch antenna model that is driven with a coaxial probe. Another way to excite the patch is by using an inset-feed. The inset-feed is a simple way to excite the patch and allows for planar feeding techniques such as a microstrip line.
