Abstract

Abstract:
Microstrip structures are easy to fabricate and reveal effective success in RF distributed
circuits such as RF filters. In this paper, the RF filter of the user equipment (UE) WCDMA
receiver (f0 = 2.14 GHz and BW = 60 MHz) is to be designed via applying three
different techniques; namely: the traditional parallel coupled lines method, edgecoupled
hairpin structure and the microstrip ring resonator method. In each case
minimizing the area is a goal. Two different types of the commercial substrates will be
used. Circuit and electromagnetic (EM) simulations will be accomplished using the
Agilent tool Advanced Design System (ADS) that uses the Momentum method in the
EM simulation. Local implementation of the designed microstrip circuits is a target.
