The angular resonant frequency ([[omega].sub.r]) of the series resonant circuit
is given by equation 21:
The series branch of series resonant circuit
[L.sub.C,p3]Cp3 will cause a spurious frequency, which is located at
This circuit model which composed of a series resonant circuit
and a parallel resonant circuit helps the analysis of the dual resonance performance of the antenna .
The load is presented by series resonant circuit
([C.sub.R], [L.sub.R], and [R.sub.LOAD]).
When using an input series resonant circuit
, the source voltage required is
For a lumped-circuit power amplifier, in order to approximate the ideal class F with harmonic impedance conditions of [Z.sub.1] = [Z.sub.3] = [infinity] and [ohm]o [Z.sub.2] = 0 [ohm]o at the device output terminal by compensating the influence of [C.sub.out], it is also advisable to use an additional parallel circuit [L.sub.2][C.sub.2] connected in parallel, as shown in Figure 4, where the series resonant circuit
[L.sub.0][C.sub.0] is tuned at the fundamental.
On the contrary, if the input impedance after step 1 in the broadband matching process has an inductive component and a capacitive component at the lower and higher band edge frequencies, respectively, then a series resonant circuit
that has its resonant frequency occurring at the center of the operating range connected in series with the aforementioned circuit is necessary.
Many of the same observations made for the series resonant circuit
oscillator apply to the parallel case.
A slot-excited T|M.sub.01~ mode behaves like a parallel resonant circuit in series with the feeder, and a post-excited T|M.sub.00~ mode is like a series resonant circuit
in shunt with the feeder.
In a simple LRC series resonant circuit
, resonance occurs at a frequency [Mathematical Expression Omitted] where [Mathematical Expression Omitted] At this frequency, the capacitive and inductive reactances are equal (and opposite in phase), such that the net reactance through the circuit is zero.
This approximation consists of a series resonant circuit
made of a capacitor between two series microstrip lines (distributed equivalent of an inductor).
