摘要
Planar hairpin resonators are considerably compact and can found numerous applications. One of them is its use as unit cell for designing different types of artificial surfaces based on periodic structures, such as EBGs or even “soft” surfaces. In this work we propose to include some varactor diodes in the unit cell with the purpose of providing reconfigurability to the structure in terms of operation frequency. The demonstrator is manufactured in a 1D multilayer version by using a microstrip line and analyzing the transmission parameter S21.
