Popis:	A novel dual-band array antenna and its associated feed networks for 2400/5800-MHz wireless local area networks (WLAN) is proposed. The nested dual-band array is composed of a 2400-MHz band array formed by 16 (4 × 4) parallel-fed rectangular patches and a 5800-MHz band array formed by 64 (8 × 8) hybrid-fed double-sided printed dipoles. The measured and simulated results are presented and analyzed. The relative impedance bandwidths and the peak gains of the 2400-MHz band and 5800-MHz band arrays reach 8%, 13% (VSWR < 1.5), 24 dBi and 18 dBi respectively. The dual-band array has regular radiation patterns, high polarization purity and antenna efficiency, and it is suitable for integration with other microwave circuits and can be applied in other dual-band system by scaling its size. The design consideration for side lobe level (SLL) suppression by amplitude weighting combining the quarter-wavelength transformer and a small adjustment in the antenna geometry is discussed as well.
