RAYSPAN® Corp., the world’s only provider of metamaterial and advanced RF air interface solutions for wireless communications, announced the availability of RAYSPAN MTM-E™ solutions for long-term evolution (LTE).


MTM-E is the only antenna solution that can support six or more bands operating from 698 to 960 MHz in the low band and 1710 to 2170 MHz as well as 2.6 GHz in the high band without requiring any switching elements or matching circuits. MTM-E is the smallest LTE antenna platform available, meeting the requirements for portable LTE devices such as mobile phones, laptops, USB dongles, wireless routers and wireless modems. The RAYSPAN MTM-E solution is the only antenna technology that offers integrated LTE, 3G, Bluetooth and GPS all from a single-feed antenna solution. “RAYSPAN MTM-E is uniquely suited to the requirements of wireless and mobile standards, and especially LTE,” stated Gregory Poilasne, VP of Business Development at Rayspan. “We are pleased to be able to offer an LTE antenna solution that not only leads the industry in performance, integration, low power consumption and time to market, but is ready for manufacturers today.” Unlike competing 3D antennas designed for LTE, the MTM-E antenna is a simple 2D design in which copper artwork is printed directly on a device’s printed circuit board (PCB) using standard PCB manufacturing techniques. This enables MTM structures to be built using the finest line widths and spacing available for antennas. These MTM structures, along with eliminating the need for switching elements and matching circuits, simplify system integration, lower power consumption, accelerate time to market and allow for smaller handset designs.

The RAYSPAN MTM-E solution complies with the current LTE standard which calls for multiple input, multiple output (MIMO) technology requiring two separate antenna structures that operate over the same frequency band, at the same time, and from the same location. The MTM-E MIMO antenna solution exhibits excellent MIMO gain performance with > 50 percent efficiency values in free-space for handset applications, better than -10 dB in near field isolation, and better than 0.3 far-field envelop correlation coefficient. The secondary LTE MIMO antenna also supports 3G diversity and GPS applications.
