Traning for Interns

In our laboratory, we conduct research on antennas—the “gateways” for radio waves. Many of the technologies that underpin modern society, such as smartphones, Wi-Fi, satellite communications, and radar, rely on antennas. However, their inner workings and the fascination they hold are not widely understood.

Antennas are profoundly fascinating devices that manipulate invisible radio waves. Since their performance can vary significantly depending on their shape, size, and placement, you can experience the excitement of both theory and hands-on engineering.

ACL Antenna Laboratory offers a university-style research environment where researchers from various backgrounds—including interns and those from outside the corporate sector—come together to pursue new possibilities for antennas through research, analysis, and experimentation. Additionally, as part of our community volunteer activities, we teach children the “joy of science” by having them build antennas and experience real-world wireless communication through amateur radio programs.

Why not join us in exploring the invisible world of radio waves and taking on the challenge of research that will support the communication technologies of the future?

(1) Akihabara Laboratory [Website］
The Akihabara Laboratory is located within the Amplett Communications Research Institute, a 15-minute walk from the world-famous Akihabara electronics district. In Akihabara—a hub for information—we conduct market research on antenna products, provide design consultation, and perform electromagnetic field analysis (simulation).

(2) Isumi Laboratory [Website］
Located in Isumi-city, a resort area on the Sotobo coast of Chiba Prefecture, the Isumi Laboratory is part of the Amprett Isumi Research Institute. Its 230-tsubo outdoor experimental facility hosts seminar sessions with interns and experiments involving large antennas.

(3) Yokohama Branch Laboratory [Website]
We measure antenna radiation characteristics using an anechoic chamber owned by Hoko Electronics Co., Ltd. (Kohoku-ku, Yokohama City, Kanagawa Prefecture), a partner company of the AMPLET Communication Laboratory.

Dr. Hideyuki Nebiya invented the Spiral Ring Antenna, and received Doctorate Degree in Electronics Engineering.

The Spiral Ring Antenna which is a small antenna having a toroidal coil shape consisting of a fixed length wire is proposed. The antenna has a size of 1/15 ~ 1/5 wavelength, and this antenna has a relatively high gain (+2.0dBi at 1/10 wavelength), and can easily be matched to a coaxial line without Balun.
