Abstract
Extendable ground arrangement for an antenna system in a radio communication device to be operating at within one or more frequency bands. The ground arrangement includes support means ( ), e.g., a slide or flap, carrying conductive ground extension means ( ). The support means has fastening means ( ) for slidably or rotatably connecting the ground extension means to the radio communication device, wherein the ground extension means is adapted to radiate at at least said first frequency and to couple, e.g., capacitively, to main ground means located in the radio communication device adjacent to said first edge. When extended the extendable ground means provides improved gain and SAR reduction.
