This material is suitable for millimeter-wave band antenna circuit boards and will start mass production in April 2019.
Currently, fluororesin circuit board materials are mainly used as antenna circuit board materials.
One reason for which class D amplifiers are interesting for RFID is that the load in the form of a series LCR circuit is precisely the equivalent of the tuned antenna circuit
that is usually connected to the reader.
In order to change the resonant frequencies, we adjust the capacitor and inductor parameters, in the antenna circuit
. Moreover, the real and imaginary impedance part of its admittance are approximately 50 and 0 Ohm, respectively, according to simulation results.
An antenna circuit
is taken into account to evaluate the metallic environment effects over the HF RFID system.
Etching is the most commonly used method to create these antenna circuit
patterns, and volume production is being carried out, lowering production costs and fueling demand even further."
Duplexer is a component that is used in an antenna circuit
, to enable duplex and simultaneous conversation by discriminating transmitting and receiving signals.
The other side of the substrate is partially metallized in the form of the antenna circuit
Theoretical results were calculated using the varactor tunable notch antenna circuit
model and Equations 2 and 3.
created by this method showed a sensitivity similar to that of antennas produced by a commercial vacuum processing technique.
