Open publisher page 0 citations

Abstract

High-impedance surface allow flush-mounted antennas to radiate efficiently.It can be fabricated using printed circuit board.Metal patches are arrayed periodically on the board.The printed circuit board treated by that method exhibits high surface impedance and a surface wave bandgap over some limited frequency range.The inductance of high-impedance surface is thought depending on the metal vias that connect two sides of printed board and gap capacity.In our experiment metal vias were instead of bead inductance.This paper presents the properties of inductance high-impedance surface.
