Patch Antennas
Microstrip or patch antennas find uses in applications that require low profile antennas without compromising performance. Most patch antennas are directly designed as printed circuit boards (PCB). The structure consists of a conducting patch and a ground plane between which is a substrate that can either be air or a dielectric such as Teflon.
All antennas in this catalog support AI-based tuning and analysis. For

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

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.
