The patch antenna, also known as a microstrip antenna, is a type of planar antenna that has found widespread application in modern communication systems due to its low profile, lightweight, and ease of integration with various electronic devices. This article delves into the various classifications of patch antennas, highlighting their unique features and areas of application.
1. Shape Classification
Patch antennas can be categorized based on their shape, which significantly influences their radiation patterns and performance characteristics.
-
Rectangular Patch Antennas: The most common form, rectangular patch antennas offer simple design and fabrication processes. They exhibit a directional radiation pattern with a main beam along the broadside of the antenna.
-
Circular Patch Antennas: Circular patch antennas offer a more omnidirectional radiation pattern, making them suitable for applications requiring broad coverage. They are also visually appealing and can blend seamlessly into various environments.
-
Other Shapes: Innovations in antenna design have led to the development of patch antennas with irregular shapes, such as triangular, hexagonal, and elliptical. These unique shapes can offer customized radiation patterns tailored to specific application requirements.
2. Feeding Mechanism Classification
The method of feeding the antenna, i.e., how the RF signal is coupled to the antenna, is another critical aspect of patch antenna classification.
-
Microstrip Line Feed: In this method, the feedline is placed parallel to the patch and connected to it via a gap or coupling aperture. It offers good impedance matching and ease of integration with microstrip circuits.
-
Coplanar Waveguide Feed: This technique involves placing the feedline in the same plane as the ground plane, simplifying fabrication and reducing cross-talk between adjacent antennas.
-
Aperture-Coupled Feed: Aperture-coupled patch antennas use a slot in the ground plane to couple the feedline to the patch. This method provides better isolation between the feed network and the radiating element, resulting in improved antenna performance.
