This paper deals with the user hand influence on impedance matching and radiation pattern of a planar inverted-F antenna (PIFA). In the text, the PIFA structure is discussed in order to achieve broadband and multiband capability. Then, the dual-band PIFA antenna for operation at frequencies of GSM900 and GSM1800 systems is designed. In the next step we investigate the user influence in data mode (the user is typing a message or browsing with a phone). For this purpose the phantom hand was made from an agar based material. The first author’s right hand was used as a template for the phantom. Numerical model was created by 3D scanning of the fabricated phantom. Finally, the comparison of the differences between simulations and measurement is presented.
