Analysis of a multiband monopole handset antenna combined with a slotted ground plane.

The ground plane of a handset device plays an important role in the radiation process. As a consequence, through a ground plane modification, it is possible to obtain a multiband performance while keeping small antenna dimensions. Numerical simulation using Method of Moments has been used to understand the effect of the slots and a prototype has been built to validate the solution. The proposal consists in a multiband planar monopole handset antenna featuring a small area of 13 mm × 11 mm with a slotted ground plane operating in multiple communication standards (GSM850, GSM900, DCS, PCS, UMTS, LTE2300, WiMAX, Bluetooth, and Wi-Fi). Thanks to the presence of the slots, the bandwidth and efficiency results have been significantly improved. © 2012 Wiley Periodicals, Inc.
