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
