A capacitive method for measuring hand grip position on a mobile phone equipped with a dual-band planar inverted-F antenna (PIFA) and a monopole antenna was studied using different electrode arrangements. A capacitive sensor with a dual-electrode configuration and an antenna-integrated capacitive sensor for hand grip recognition were developed. The(More)
Thin nano-particle conductors of the order of micrometer in thickness are typical for printable electronics technology. A two-dimensional (2-D) eigenmode solver based on Jacobi-Davidson algorithm is applied to printable transmission lines to evaluate the conductor loss. Efficient preconditioning for the interior solver is utilized to treat(More)
An antenna integrated sensor implementation for hand or finger proximity recognition is developed. Capacitive sensor was installed on the antenna of functional Nokia 6021 phone. The sensitivity of the phone with planar inverted F antenna (PIFA) integrated sensor was measured with active TRP (total radiated power) and TIS (total isotropic sensitivity)(More)
