This letter presents a new planar inverted-F antenna design that is dedicated for integration within mobile devices such as phones and tablets. The proposed antenna structure is based on nested capacitive slots in order to achieve a multiband behavior. The presented antenna is also reduced in size by 60%. The antenna is then reconfigured using positive-intrinsic-negative (p-i-n) diodes that are embedded within the antenna structure. Frequency reconfiguration is achieved to ensure that all the various commercial and required bands of interest are covered. Two prototypes are fabricated and measured where good agreement is noticed between the simulated and measured data.
