Abstract :
This paper presents the design of gap-coupled series fed antenna array with improved bandwidth. The series-fed array is designed using `U´ shaped microstrip feed lines and parasitic elements gap-coupled to non-radiating edges of the central elements. The fabricated 3 element gap-coupled series-fed array has VSWR <;2 bandwidth of 5.5%, achieving 3 times improvement in bandwidth as compared to conventional array. The 3 element gap-coupled series-fed array has maximum gain of 13.1 dBi at 5.75 GHz and cross-polar levels <;27 dB.
