In Figure 7, S-parameters of distributed 1-cell CRLH TL structure and equivalent LC circuit model are presented.
When the antenna is near the sensor, the magnetic energy is transmitted by the inductance coil of the LC circuit [10].
The LC circuit selectors are available in three-, six- and eight-way configurations and can be stacked for up to 10-way circuits.
A resistance R is added to the LC circuit to model the radiation, conductor, and dielectric losses.
Note that this behavior can be qualitatively predicted from the LC circuit, since for very small holes the corresponding inductance, L, is also small, the capacitance, C, takes large values and the bandwidth of such resonators is known to be very narrow [25].
However, the attenuation pole location, which corresponds to the resonance frequency of the parallel LC circuit, also shifts toward lower frequency range because of the fact that as the series inductance increases, the resonance frequency of the equivalent parallel LC circuit decreases.
Resistor [R.sub.07] attenuates the external LC circuit further and reduces the harmonies.
Hence the mushroom EBG can be modeled as an LC circuit with inductance and capacitance given by the following equations:
Acquired signal is passed through a resonant LC circuit. The center frequency of the contour is matched to the carrier frequency of the information signal, quality of the resonant circuit--4.
It makes use of the parallel LC circuit per unit length mode,|4,5~ shown in Figure 2.
3, both the [jx.sub.s] block and [jb.sub.p] block can be realized with a parallel LC circuit thus we get the circuit of the impedance transformer as shown in Fig.
Using the above formulas, a preliminary waveguide combiner structure was obtained; the cross-section of which is shown in Figure 3, below the prototype LC circuit.
