Ceramic dielectric antenna can be used not only in GPS global positioning system, but also in communication between modern Internet of Things devices. The company in line with the achievement of customers, achievements of their own business philosophy, to provide customers with professional, targeted product design (customers to provide product requirements).
According to the different needs of customers, the company can provide different shapes of antenna, generally for the plate dielectric antenna and rod dielectric antenna.
Product description
The company has now successfully developed multiple media antennas.
K25, K35, K37, K40, K45
It has different dielectric constant and working frequency, and is widely used in:
GPS ceramic antenna;
Beidou satellite antenna;
Timing antenna;
10X10mm to 100X100mm can be used for the size of ceramic antenna;
Custom-made ceramic antenna products.
The company's existing products are applicable to the range of working frequency range from 30MHz to 10GHz. If the company needs the company to develop the corresponding low frequency and higher frequency products according to the requirements of the customer.
Product information
Huifeng electronics has now set up two kinds of dielectric antenna products:
產品A：
尺寸：25mm*25mm
介電常數：20
工作頻率：1.57542GHz |
產品B：
尺寸：20mm*20mm
介電常數：37或40
工作頻率：1.57542GHz |
產品C：
尺寸：18mm*18mm
介電常數：37或40
工作頻率：1.57542GHz |
|
The existing products use the same size of the vibrator, its size: 1.4mm*7.0mm, the product surface coating with silver layer, according to the different working frequency demand, can adjust the size of the silver layer coverage to achieve different working frequencies.

Application of dielectric antenna
With the development of new technology, miniaturized dielectric antennas are increasingly used in new products, such as:
Satellite navigation;
RDIF logistics field;
Wireless communication router;
Mobile phone built-in antenna;
Communication base station;
Dielectric resonator antenna;
Radar;
Satellite TV set-top box;
The Internet of things equipment has a built-in communication antenna ect.
The company has a certain accumulation of technology in various fields of dielectric antenna, can provide customers with different requirements of professional dielectric antenna design.
Application characteristics of dielectric antenna
Microwave dielectric ceramics (MWDC) have the characteristics of high dielectric constant, low dielectric loss, high quality factor and small resonant frequency temperature coefficient. After applying the dielectric resonator antenna, the dielectric constant of dielectric resonator has a wide selection range (6~140), allowing the designer to control the scale and bandwidth flexibly, the radiation efficiency is more than 95%, and the shape is more than 95%. The antenna design has greater flexibility, more feeding mode, simpler processing and lower cost, and is convenient for integrated design.
Technical index of dielectric antenna
The dielectric constant is 6.1 + 0.2, 10 + 0.2, 14 + 0.2, 26 + 0.2, 35 + 0.2;
Loss angle tangent: < 3 x 10-4;
The frequency temperature coefficient: < < f > < < 10ppm/ >;
Bending strength: more than 100MPa;
Resistivity: > 1012 Omega cm;
The thermal conductivity is greater than or equal to 3W/m. K, which meets the high power requirements of microwave devices.
