Compact microstrip low‐pass filtering power divider with wide harmonic suppression

Abstract: A compact, low‐cost Wilkinson power divider (WPD) of 1.3 GHz (f0) operating frequency, with a low‐pass filtering response, is presented in this study. Power division and low‐pass filtering responses are both achieved by using two symmetrical units of interdigital line resonators (ILRs). Each square unit of ILR exhibits a low‐pass filtering response, with a minimum insertion loss of 0.3 dB. The dumbbell‐shaped, defected ground structures are introduced for widening the attenuation band by suppressing the harmon… Show more

“…EM-driven design is of paramount importance especially for systems where simpler performance evaluation methods (e.g., equivalent network models) lack the accuracy. Representative examples include miniaturized microstrip components 15 18 , often implemented by folding conventional transmission lines (TLs) 19 , 20 , replacing TLs by compact microstrip resonant cells (CMRCs) 21 , 22 , or incorporation of the various topological alterations (e.g., defected ground structures 23 , substrate integrated waveguides 24 , stubs 25 , slots 26 , etc.). All of these result in strong cross-coupling effects, and the increased number of geometry parameters.…”

“…The S 11 of some power dividers with harmonic suppression have been shown in Fig. 4.9, from [122], [123], and [124]. It can be seen that the S 11 spectrum is shown atleast up to 10 GHz to convey that the 2 nd , 3 rd or even 4 th harmonics have been suppressed.…”

“…For example, antennas with power divider operating at 2.4 GHz may also receive spurious signals at harmonic frequencies, which are multiples of 2.4 GHz, i.e., 4.8 GHz, 7.2 GHz, 9.6 GHz, etc., which is undesired.
