Microstrip antenna : Simple
Easy with MIC
Low cost
Low profile
Background
How to manufacture a microstrip patch antenna for wireless communication at 2.4 GHz ?
Whether the microstrip antenna can be used as client antenna in computer?
Problem
Feed Technique
Coaxial Feed
The Coaxial feed or probe feed is a very common technique used for feeding Microstrip patch antennas
Comparing Feed Techniques
Transmission Line Model
Method of Analysis
Design Specification fo = 2.4 GHz Єr = 1.03 h = 12 mm Feed Technique : Coaxial Feed Method of Analysis : Transmission Line Model
Antenna Design
By transmission line calculations, we get : L = 46.2 mm
W = 64 mm
Lg = 118 mm
Wg = 134 mm
Feed Point Locations
Simulation
Testing and Results
The signal strength (Gain) of microstrip patch antenna compared with omnidirectional antenna is 15 dB.
The radius of microstrip patch antenna is about ±200m
The Half Power Beamwidth of microstrip patch antenna is 40°
There is still back lobe in radiation pattern of microstrip antenna
Microstrip patch antenna can be used as client antenna in computer
Conclusions
Thanks for your attention
