IEEE International Symposium on Antennas and Propagation, Illinois, United States Of America, 8 - 14 July 2012
Because of the design limitations of conventional high impedance surfaces (HIS), it is not possible to miniaturize the HIS and increase the bandwidth, simultaneously. To overcome this, a novel HIS is proposed with a periodically perforated ground plane. The magnetic flux flowing through the perforations results in an extra inductance which increases the fractional bandwidth and decreases the center frequency.
