A miniaturized monopole antenna was designed and fabricated on an organic paper and LCP material for wireless body area network. Compared with previous work, the proposed design has 20% reduction of the antenna size but with enhanced performance. The effects of the compact coplanar antenna under different twisting conditions is described in this paper. The proposed antennas are simulated and designed on an organic paper and a Liquid Crystal Polymer (LCP) substrate with dielectric constant D= 3.4 and thickness 15μm and 5μm respectively, occupying the area of 22×30mm. A detailed discussion about radiation pattern, Gain, antenna efficiency and power pattern is given with the help of experimental and numerical results.
