                       Background
Microstrip antenna :
 Simple

 Easy with MIC

 Low cost

 Low profile
                    Problem
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?
                     Feed Technique

Coaxial Feed

The Coaxial feed or probe
feed is a very common
technique used for feeding
Microstrip patch antennas

                           Antenna Design
Design Specification
     fo = 2.4 GHz
     Єr = 1.03
     h = 12 mm
     Feed Technique : Coaxial Feed
     Method of Analysis : Transmission Line Model
By transmission line calculations, we get :
     L = 46.2 mm

     W = 64 mm

     Lg = 118 mm

     Wg = 134 mm

Testing and Results
                                Conclusions
 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
