The frequency reconfigurable volumetric PIFA
presented in this paper is designed to switch between two US
public-safety bands, one operating at 700MHz and the other
having a bandwidth of 17% around 850MHz - in effect covering
a range from 800MHz to 900MHz. The reconfigurability is
limited to only the ground and patch layers as an aim to
minimize the number of MEMS switches used. The radiation
pattern of the antenna maintains its shape and the maximum
gain over this reconfigurable band of operation, 700 – 900 MHPostprint (published version
