Preview
Dielectric antenna is fed using coaxial ceramic media. By a coaxial extension of the inner conductor to form an
oscillator, used to excitation of electromagnetic waves, the sleeve of the role of the media, except clamping bar,
the more important is the reflection of electromagnetic waves, thus ensuring the incentives from the coaxial line
inner conductor of electromagnetic waves to the free end of dielectric rod transmission.
Token use of low-loss dielectric antennas, high-frequency dielectric material, strict process control, apply to the
Global Positioning System (GPS), radio broadcast system of small antenna elements.
Token electronics manufacturing dielectric patch antenna with rectangular microstrip antenna design and offset
one point feeding method for Global Positioning System GPS, media filters, multi-layer filters, cavity filters,
band-pass filter, military filters, high-frequency filters and so on, in line with RoHS standards.
DA series of microwave antenna, which provides clients a custom design and deliver smaller tolerances.
Dielectric antenna application specific design, but also for the frequency requirements, including different
inductance values and Q specifications adjusted.
Token will also produce devices outside these specifications to meet specific customer requirements,
please contact our sales for more information.
