The characteristics of antennas, including built-in antennas, and the mechanism by which stable performance is achieved.
The optimal shape of an antenna varies depending on the frequency and application. The most efficient antenna is one that is half the length of the wavelength of the frequency being used. High-frequency waves, which are the source of radio waves, have the property of reversing polarity every half wavelength. Therefore, when the length of the antenna conductor exceeds half a wavelength, the transmission and reception of radio waves do not work well. By making the length of the antenna conductor half the wavelength of the frequency, the radio waves resonate with the antenna. By adjusting the length of the antenna according to the wavelength of the frequency, the antenna and the transmitted radio waves enter a resonant state, allowing maximum power to be radiated. Similarly, in a receiver, the received radio waves and the antenna enter a resonant state, enabling the capture of maximum power.

Company information
Our manufacturing started with components for cutting-edge communication devices, including "antennas built into mobile phones." Our know-how and technology are concentrated in these small precision parts. With well-equipped facilities and experienced engineers, we respond to our customers' needs through speedy and high-quality parts manufacturing, while continuously pursuing the forefront of technology as a group of engineers. Currently, leveraging the technology cultivated through precision parts, we specialize in waterproof components that encapsulate chip-mounted substrates and sensors, and we handle everything from design to manufacturing of parts up to palm-sized that enhance added value through insert molding. Additionally, we arrange spring materials, pressed products, and machining (from resin and metal lathe processing to machining). We also perform assembly work and produce parts that are insert molded with resin. We welcome inquiries for mold transfers for insert molding and for small-batch, diverse products. We offer a one-stop service from development to manufacturing and shipping.
