摘要：
Microstrip antenna is suitable for mobile handsets due to its light weight and compactness. Its disadvantage of narrow bandwidth is necessary to be improved for modem wireless communication systems. This paper proposes a lump element model for the analysis of a coupled microstrip antenna and illustrates the appropriate coupling coefficient for bandwidth enhancement. This condition can be achieved by using serration of coupled microstrip antenna. Return loss of this antenna is analyzed in terms of serration and the obvious characteristics improvement can be observed. It is found to be useful for the practical wireless communication systems.
