Miniaturized microstrip dual‐band power divider on localized substrate integrated artificial dielectric

Localized substrate integrated artificial dielectric (L-SIAD) is a structure with only metallic posts right under microstrip line, leading to planar microstrip circuit miniaturization.When compared with original substrate integrated artificial dielectric (SIAD), the fabrication for L-SIAD will be more economical and easier, whereas the characteristics of L-SIAD is almost the same as that of original SIAD. A microstrip dual-band power divider on L-SIAD exhibits an area reduction of about 40% compared with that on regular substrate. By proper design of L-SIAD, more area reduction can be achieved. © 2010 Wiley Periodicals, Inc.
