What Is a Patch Antenna?
A patch antenna is a type of planar antenna constructed by mounting a metallic conductor pattern onto a dielectric substrate. This configuration creates a microstrip line, facilitating efficient transmission and reception of radio waves through resonance.
The antenna’s conductor, often square or circular, vibrates in harmony with the microstrip line to emit radio waves. This resonance mechanism induces voltage within the microstrip line when exposed to radio waves, converting these interactions into usable signals.
Patch antennas are valued for their compact and lightweight design, cost-effectiveness, and high gain. Their planar structure allows for a minimal footprint, while their flexible design accommodates various shapes, enhancing adaptability to different applications.
