A miniascape-like triple-band monopole antenna designed for wireless body area network (WBAN) applications is presented in this letter. With a miniascape-like strip composed of an S-shaped strip, a U-shaped strip, and an I-shaped strip, three operating bands covering 3.1-3.3, 4.2-4.9 and 6-10.6 GHz for VSWR <= 2 are obtained, respectively. A quarter-circle cutting from the ground enhances the impedance match in the higher frequency band. Compared to previous wireless body area network antennas, the proposed antenna achieves a compact size of 23.6 x 35 mm(2) with low profile (thickness of 0.05 mm) and can conform to the human body. The experimental results for the VSWR characteristics and radiation patterns show good agreement with the simulated ones.
