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
