A Coupled Microstrip Antenna Employing Serrated Coupling

Abstract

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 modern wireless communication systems. This paperproposes the serration of coupled microstrip antenna to improve impedance characteristic.
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.
