As the MA monomer is electron deficient and BMA monomer is electron rich, the MA with BMA neighbor will be more shielded due to the inductive effect and will show the upfield chemical shift, whereas BMA will show a downfield chemical shift.
A perturbation in the corner-cut can produce an inductive effect, which leads to a Chebyshev characteristic.
In this paper, two novel parallel matching methods are proposed with which the capacitive and inductive effect can be canceled simultaneously so that the low insertion loss and relatively high isolation performance can be expected.
