ra_005Theory and Experiment on Microstrip Antenna Y. T. Lo, D. Solomon, W. F. Richards IEEE Transactions on Antennas and Propagation, Vol. AP-27, No. 2, March 1979 Final-term Report Reporter : P93942003 Yu-Shu Chen 1 21st Dec. 2004 Strength and Weakness of Microstrip Antenna Strength Low in profile Light in weight Compact and comfortable in structure (Co-planar structure) Easy to fabricate To be integrated with solid-state devices Weakness Narrow bandwidth (Cavity based model Only operate in a specific range of frequencies Fading out of operation frequency) Low efficiency 2 Methods on Analysis of Microstrip Antenna Cavity Model Transmission Line Theory Only being able to deal with several microstrip antenna with simpler geometric shape (e.g rectangle, circle etc.) F……
