Abstract :
The most serious limitation hindering the wider application of microstrip antenna technology is the narrow bandwidth of the basic element. For this reason, many elements with enhanced bandwidth have been investigated. This paper presents measured results for an under-coupled microstrip patch antenna with the improved bandwidth. The impedance was matched by an open-circuit tuning stub connected in shunt with the feed line
