Design and implementation of a novel microstrip filter

Abstract

Microwave filters are circuits which perform signal processing functions, particularly to eliminate unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be passive or active(depends on components used) Analog or digital(depends on input signal) High-pass, Low-pass, Band-pass, Band-stop or all other pass (depends on frequency) Infinite impulse response (IIR type) or Finite impulse response (FIR type) (Depends on response) Microstrip is a type of electrical transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave frequency signals. Microwave components such as antennas, couplers, filters, power dividers etc can be formed using microstrip line. This paper aims on filter design, using microstrip transmission line, with a Non-Periodic technique especially using Defected Microstrip Structure to be operated in the C – Band frequency.
