Introduction
Nowadays, patch antennas are used in many applications, including wireless communication, GPS devices, RFID, etc.
In this article, you will find out what a patch antenna is and what it consists of. We will also take a look at some of the most popular AccelTex patch antennas.
A Patch Antenna & Its Components
A patch antenna is compact and has a low profile, it is widely used in wireless communication systems as it is easy to integrate into various devices. Such antennas can be mounted on a flat surface.
The Components of a Microstrip Patch Antenna
Radiating Patch
The radiating patch is the most important element. As a rule, it is made of a conductive material (copper or gold), and shaped in a specific geometric pattern. Patch shapes can be rectangular, square, circular, or elliptical. The dimensions of the patch, including its length, width, as well as shape, determine the operating frequency and radiation characteristics of the antenna.
Dielectric Substrate
A dielectric substrate offers mechanical support as well as electrical insulation. The radiating patch is mounted on it. Typically, the substrate is made of low-loss materials with a high dielectric constant, for instance, fiberglass-reinforced epoxy. Note that the material of the substrate plays a crucial role in the performance, bandwidth, and also efficiency of the antenna.
Ground Plane
Beneath the substrate, there is a conductive ground plane that serves as a reflector, enhancing the radiation efficiency of the antenna by providing a return path for the electromagnetic waves. Usually, the ground plane is larger than the radiating patch.
Feeding Mechanism/Transmission Line
A transmission line feeds the radiating patch. It is done using a microstrip or coaxial cable. The feeding mechanism connects the patch to the radio frequency signal source, it determines the patch antenna radiation pattern as well as the polarization of the antenna.
The transmission line provides the necessary radio frequency signals to generate electromagnetic waves. The patch and the substrate form a planar structure, making microstrip patch antennas flat and also lightweight, perfect for applications where weight and space are important.
Microstrip patch antennas can be designed to operate at specific frequencies within the microwave range by adjusting the dimensions of the radiating patch and the properties of the substrate. As a result, antennas can be customized to meet the requirements of various wireless communication applications.
