摘要：
This paper presents a triple-band printed-circuit-board microwave absorber for applications in 2.4GHz WLAN and 3.5/5.8GHz WiMAX bands. The absorber consists of simple geometries with tuning elements and chamfering, which can significantly reduce the modeling errors. The study and design processes are based on numerical simulations. The simulated results show the absorption bandwidths (at 50%) of 160MHz (2.36-2.52GHz), 160MHz (3.48-3.64GHz) and 520MHz (5.54-6.06GHz). The absorptions at the center frequency of each band (i.e. 2.45, 3.55 and 5.78GHz) are also found feasible at 97.6%, 85.2% and 96.0%, respectively. From the study, the proposed absorber is applicable for a fairly wide-angle of wave incidence and suitable for a number of applications in the specified bands. The main advantages of the proposed absorber are thin, simple and low-cost structure, which can be very useful for various applications in WLAN and WiMAX bands.
