Ethertronics was a global leader and innovator in ultra-high performance smart antenna system solutions for wireless communications. The company specialized in designing and manufacturing standard and custom antenna solutions for a wide array of wireless devices, including smartphones, tablets, PCs, IoT devices, wearables, medical, and automotive applications. Known for its patented Isolated Magnetic Dipole™ (IMD) technology and active antenna systems, Ethertronics focused on enabling enhanced wireless performance, higher data rates, and better connectivity in compact designs. In November 2015, Ethertronics was acquired by AVX Corporation, which itself later became part of Kyocera Corporation, now operating as Kyocera AVX Components Corporation. Ethertronics' technologies and expertise have since been integrated into Kyocera AVX's extensive portfolio of electronic components.
Served as the central hub for research and development, engineering, corporate leadership, sales, marketing, and administrative operations for its global antenna business before the acquisition by AVX.
The facility likely housed advanced RF testing laboratories, anechoic chambers for antenna design and validation, and engineering development spaces, typical for a leading-edge wireless technology company.
Prior to acquisition, the work culture was likely dynamic, innovative, and fast-paced, driven by the demands of the rapidly evolving wireless industry. It would have fostered engineering excellence and customer-focused solutions.
The San Diego headquarters was pivotal for Ethertronics' innovation in antenna technology, establishing its reputation as a leader in the field and driving its global market presence.
Prior to its acquisition by AVX (now Kyocera AVX), Ethertronics maintained a significant global presence to support its worldwide customer base. This included R&D and corporate functions primarily in the USA and France, with a strong network of sales offices, field application engineers (FAEs), and manufacturing support strategically located in key technology and manufacturing hubs across North America, Europe (notably France), and Asia (including China, Taiwan, South Korea, and Japan). This network enabled Ethertronics to provide design, development, and support services for its advanced antenna solutions to leading wireless device manufacturers globally.
