Abstract
A compact embedded tapped‐line combline filter with interdigital capacitors using low‐temperature co‐fired ceramic (LTCC) technology for wireless application is proposed. The interdigital‐type capacitors have been loaded to reduce the geometrical length while extending the electrical length. The fabricated filter has a relatively small size, 2.7 × 2.03 mm, and good characteristics at the 5‐GHz range. Its small size and relatively simple structure make it a good candidate as an integrated filter for various LTCC substrates. © 2004 Wiley Periodicals, Inc.
