Research and development system

Two R&D bases

Combining technological capabilities to meet diversifying needs
Bringing together people, passion, and technology.
Power with an eye to the future is here.

Japan DX Antenna Co., Ltd. has two research and development bases: Seishin Technology Center (Kobe) and Kawasato Factory (Kanto).
By bringing together the strengths of both locations, we have built a system that handles everything from development to quality assurance.

Two R&D bases

As a "base of knowledge and technology responsible for manufacturing", our company conducts research and development at two bases in Kobe and Kanto. At the Seishin Technology Center in Kobe, the two divisions of development and quality assurance work together to promote research and development of antenna-related products and wireless technology. By utilizing manufacturing technology and creating products that incorporate the customer's perspective, we have built a system to quickly and accurately produce next-generation wireless technology and products that are compatible with complex usage environments. On the other hand, the Kawasato factory is equipped with one of the largest anechoic chambers in Japan and various reliability testing facilities, and as a base responsible for performance evaluation and quality assurance of mass-produced products, it supports the strength of being able to consistently verify everything from development to mass production and quality confirmation in-house.

To improve the quality of manufacturing

In order to meet the needs of our customers and advance the quality of our products to a higher level, we are enhancing our research and development capabilities by enhancing our equipment, including EMC anechoic chambers, large anechoic chambers, and various testing laboratories.

By establishing this research and development system, we have realized the smoother, faster, and more accurate development of products compatible with ultra-high frequency next-generation wireless technology and more complex usage environments. It embodies the latest technology with high precision.

anechoic chamber
Seishin Technology Center has introduced the latest advanced equipment [anechoic chamber] for use in strengthening EMC and designing wireless equipment.

Large anechoic chamber

An anechoic chamber that supports a wide range of frequencies from broadcasting bands to millimeter wave bands (76MHz to 60GHz).
It will be used for the design, development, and verification of general wireless systems, including multimedia broadcasting equipment using V-Low and V-High, which will be launched in the near future, and millimeter wave transmission systems.
We will respond quickly to broadcasting, communication, and information services that are becoming more sophisticated, complex, and diverse.

Large anechoic chamber

EMC anechoic chamber

With the rapid development and spread of mobile devices and information terminal devices, it has become essential to deal with electromagnetic waves emitted by the devices and comply with the VCCI standard.
Our EMC anechoic chamber allows us to conduct radiation noise evaluation tests that comply with the 3m method based on the representative VCCI/FCC standards for EMC evaluation, making it possible to provide highly reliable products.
We are the first in the industry to verify the impact of radio waves from wireless services, which will become increasingly popular in the future, on TV reception.

EMC anechoic chamber

Medium-sized anechoic chamber

A compact range system installed in an anechoic chamber enables ultra-high frequency measurements that support a variety of communication frequencies such as satellite antennas and millimeter wave transmission systems. We respond quickly to digital technology that is evolving day by day.

Medium-sized anechoic chamber

Small anechoic chamber

A small anechoic chamber that supports ultra-high frequency bands such as microwaves, including the 60 GHz band, where services are expected to expand in the future. By specializing in ultra-high frequency bands, we enable efficient and timely product development.

Various testing rooms

In order to develop products that can be used with peace of mind even in the more complex and harsh environments associated with the recent abnormal weather, we have newly established a test room that is designed for a variety of usage environments, and are conducting evaluation tests and verification under severe conditions.

For measures against heavy rain and typhoons

Water resistant

examination room

We conduct evaluation tests for water resistance and water resistance under the assumption that outdoor products will be exposed to more wind, rain, and water splashes than ever before, such as during abnormally torrential rains and increasingly powerful typhoons.

For measures against heavy rain and typhoons

To prevent air pollution and corrosion

gas resistant

examination room

We evaluate air pollution due to an increase in harmful substances in the atmosphere, exhaust gas, and metal corrosion of outdoor products due to gases assumed to be used in hot spring areas, and reflect this in our products.

To prevent air pollution and corrosion

For safe delivery to customers

vibration fall

examination room

In order to safely deliver products to customers across the country, we reproduce and evaluate vibration waveforms that simulate the transportation of cargo by truck, sea, air, etc.

To prevent an increase in lightning strikes

shock wave resistant

examination room

In light of the fact that damage to equipment due to induced lightning is also increasing with the increase in lightning strikes, we are conducting lightning performance evaluation tests that assume even harsher environments than before.

To prevent salt damage

salt spray

examination room

We have reflected the results of long-term evaluation tests on rust on equipment and metal fittings in consideration of salt damage caused by sea breezes in coastal areas.

To prevent salt damage

To counter temperature changes

constant temperature

tank

We evaluate equipment by assuming a variety of operating temperature and humidity environments, taking into account the rise in environmental temperatures and temperature differences due to abnormal weather, and the regional characteristics of Japan from north to south.
