Dielectric Patch Antenna (DA)

DeMint (DA) Dielectric Patch Antenna Technology Makes The List. 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.

DeMint 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.

DeMint 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.

DeMint will also produce devices outside these specifications to meet specific customer requirements,
