Ground plane plays a significant role in the radiation of handset devices. Through a ground plane modification, it is possible to obtain a multiband performance while keeping the same antenna geometry and small volume, which means that the design and intelligence relies on the ground plane. Numerical simulation has been used to understand the effect of the slots and a prototype has been built to validate the present solution. The proposal consists in a multiband planar monopole handset antenna of 13 mm × 11mm with a slotted ground plane operating in multiple frequency standards (GSM850, GSM900, DCS, PCS, UMTS, LTE2300, WiMAX, Bluetooth and WiFi).
