The Electronic Materials & Components Company of Mitsubishi Materials Corporation (President: Akira Takeuchi; capital: 119.4 billion yen; hereinafter "Mitsubishi Materials") is pleased to announce the development of multiband*1 antennas for in-vehicle telecommunications equipment supporting cellular bands*2 worldwide through the utilization of ceramics technologies and the know-how of antenna designs which have been cultivated over many years. The samples will be available from October, 2017.
In recent years, attention has been paid to technologies that provide a wide range of new products and services, such as Connected Cars*3 and ITS (Intelligent Transport Systems)*4, by connecting in-vehicle telecommunications equipment, including Telematics*5 boxes, directly to the Internet. Unit antennas supporting global cellular bands are installed in in-vehicle telecommunications equipment, which work as part of the telecommunications ECU (Electronic Control Unit)*6. It is expected that the need for them will expand as a means of collecting detailed information from the cloud on a real-time basis, including maps and roads needed for new services such as eCall (in-vehicle emergency call system)*7 and autonomous driving technologies.
In-vehicle telecommunications equipment such as Telematics boxes has high technological hurdles to overcome, for instance, the need for high-speed data communications as well as different cellular bands depending on the country, region and cellular phone carrier. For this reason, unit antennas that supported the cellular bands of each region were previously required. Mitsubishi Materials solved this by utilizing its accumulated design technologies and achievements for ceramic chip antennas, and successfully developed multiband antennas, which are unit antennas for in-vehicle telecommunications equipment that support cellular bands worldwide. Multiband antennas are expected to contribute to the global standardization of in-vehicle telecommunications equipment in the future.
These multiband antennas conform to AEC-Q200 Grade 2 in-vehicle standards for the operating temperature limits (temperature range: -40 to 105 ℃), and also cover frequency bands from 699 to 3,950 MHz.
In order to promote the effective use of Mitsubishi Materials' products, including the developed multiband antennas, Mitsubishi Materials will support antenna designs to meet the needs of customers. It will also propose an optimal wireless communication environment through the utilization of its specialized facilities, and by evaluating and analyzing conditions such as the customer's product structure, parts layout and installation environment using the following methods.
We set a vision to clarify what we want to become based on our corporate philosophy as follows: "We will become the leading business group committed to creating a sustainable world through materials innovation, with the use of our unique and distinctive technologies, for People, Society and the Earth." The Electronic Materials & Components Company will continue to contribute to society by providing unique electronic materials and components and related services to customers in a timely manner.

Dimensions: The protruding parts and the cable are excluded.
Coaxial cable: "1.5" indicates 1.5 mm in the external diameter of the insulator. "D" indicates 50 Ω (ohm) in characteristic impedance of cables.
However, the shape and specifications of the product is subject to change without notice due to product development.
(Explanation) The vertical axis shows Total Radiation Efficiency, which indicates the ratio of radiation power to the power supplied to the antenna. The horizontal axis indicates Frequency. The above figure reveals that radiation efficiency is maintained in the wide bands in the blue tinted area, which indicates the frequencies of the cellular bands worldwide, and that constant antenna performance is achieved, specifically -5 dB or higher. However, this performance shows representative values, and it does not mean guaranteed values.
