Front End | News Strong performer on EU 868 MHz and US 915 MHz networks
A T
ntenova, the UK-based manufacturer of antennas and RF antenna modules for M2M and the IoT, has launched a low-profile antenna displaying strong performance on both Europe’s 868 MHz bands and the US 915 MHz bands. The new antenna is named ‘Lama’, part number SRFI065. It was developed for small connected devices operating on the LP-WAN networks including LoRa, Sigfox, Wi-SUN and MIoTy. This antenna uses the ISM frequencies in Europe and America or both, which means that one product design can be sold in both US and European markets.
Lama is particularly small, making it suited to designs with limited real estate. It is a flexible printed circuit (FPC) antenna measuring 35 x 10 x 0.15 mm, supplied with a standard 100 mm RF cable with I-PEX MHF connector. This shape allows it to be mounted several different ways in a design. The antenna performed equally well in tests for the 868 MHz and 915 MHz bands, showing a peak efficiency at 60 per cent, and maximum VSWR of 1.5:1 for both frequency bands. The LP-WAN networks, also known as ISM, use frequencies 863 - 870 MHz in Europe and 902 - 928 MHz in the US. They are licence-free bands which are typically used to connect
large fleets of low powered devices which transmit small packets of data across large physical distances at low bit rates.
These characteristics make the Lama antenna a good choice for small networked devices operating across wide geographic areas in IoT applications. Lama will suit agricultural applications using cloud- connected sensors to measure ground
Developers can test graphene-based sensors on large scale and at low cost

he 2D Experimental Pilot Line (2D-EPL), a project grown from the Graphene Flagship, has launched its first customisable wafer run. As one of five multi-project wafer (MPW) runs, this first phase targets sensor applications. Companies, universities and research institutes can include their designs as dies on joint wafers, to test their ideas for devices on a larger scale at relatively low costs. The 2D-EPL is a €20 million project aiming to pioneer the fabrication of prototype electronics and sensors based on graphene and related materials (GRMs), and at integrating them into established silicon semiconductor platforms. While doing so, the project will also refine and scale up the
manufacturing process of graphene-based electronics, including developing critical tools, materials and processes.
The 2D-EPL includes partners from across the whole value chain – from tool manufacturers to semiconductor fabrication lines – including Chalmers University of Technology, Sweden; Aixtron, Germany and United Kingdom; Interuniversity Microelectronics Centre (imec), Belgium; AMO, Germany; VTT, Finland; Süss MicroTec, Germany; Graphenea, Spain; Micro Resist Technology, Germany; Innovations for High Performance Microelectronics (IHP), Germany, and Oxford Instruments, United Kingdom. The 2D-EPL project will offer several kinds of integration services, including multi-
project wafer (MPW) runs. The first run will be hosted in AMO GmbH’s 400-m2 state-of-the art cleanroom. Target applications are bio, gas, or chemical sensor, hall
sensor or photodetector applications, taking advantage of graphene’s extreme sensitivity to the environment. The baseline process is a graphene field effect transistor (GFET), with several customization options. The MPW run offers participants a unique chance to acquire GFETs on dies manufactured to their own designs. The cost of production is shared between the 2D-EPL project and the customer, meaning that companies, universities and research
institutes can access this technology at a much lower price point. At this time, the quantities available are suited for prototyping, research and development.
The first 2D-EPL MPW run opened for applications on 1 February 2022 and the call closes on 30 June 2022. The manufacturing stage of the MPW run will take place between 1 September and 31 October 2022. To apply to be part of the 2D-EPL’s first MPW run, visit:

moisture or temperature or to track livestock, e.g. cattle. It will also suit remote-controlled applications such as meter reading, environmental monitoring and connected services in smart cities controlling street lighting, parking sensors or waste bins. In other IoT sectors, the Lama antenna fits commercial applications in cold chain transport, distribution, logistics and tracking of goods and containers.
