Surrey Satellite Technology Ltd (SSTL) has a long history in advanced GNSS technology ranging from space GPS receiver design up to Galileo GIOVE mission and FOC payloads. SSTL is planning the development of a triple frequency antenna for new precise spaceborne GNSS applications, as suitable compact triple frequency antennas are not available commercially in the configuration required. Hence SSTL is proposing a novel antenna design for this competition that meets both the needs of its space requirements and also the needs of this SBRI call - i.e. small, robust, high performance, and low cost, in a configuration that also lends itself to low cost mass manufacture.An interdigital design has been adopted that allows the achievement of resonance at three frequencies within a single patch-like element. This avoids the need for stacking multiple elements, or for a standing off from a ground plane as is required for a wideband spiral. The design does not require unusually high or stable dielectric material, and can be be accommodated within 1 mm thickness (initially excluding radome).For generic application, a wideband Low Noise Amplifier is integrated with the antenna that can be operated off 3 to 5V, but this can be deselected as a manufacturing option to transform it into a passive antenna. The LNA will add 0.5 mm to the package, though this could be recessed into the mounting panel to maintain the 1 mm profile (excluding radome). Gains of 20 dB and 45 dB will be supported. This approach will allow reception of L1, L2 and L5 signals, within a suitably small package that the antenna could be incorporated into a CPRA (phased array). SSTL has anechoic facilities for tuning functional test, and has partners who are able to offer calibrated antenna measurement chamber. For subsequent phases, SSTL can manufacture and test small quantities of antennas, but would expect to licence the design to a mass product manufacturer, exclusively if required, as long as the IP for use in space applications is maintained by SSTL.

萨里卫星技术有限公司（SSTL）在先进的全球导航卫星系统技术方面有着悠久的历史，从空间全球定位系统接收机设计到伽利略GIOVE使命和FOC有效载荷。SSTL正在计划为新的精确的星载全球导航卫星系统应用开发三频天线，因为在商业上没有所需配置的合适的紧凑型三频天线。因此，SSTL提出了一种新颖的天线设计，以满足其空间需求和SBRI的要求-即小型，坚固，高性能和低成本，在配置中也适用于低成本的大规模生产。叉指设计已被采用，允许在一个单一的贴片式元件内实现三个频率的谐振。这避免了堆叠多个元件的需要，或者避免了宽带螺旋所需的远离接地平面的需要。该设计不需要非常高或稳定的介电材料，并且可以容纳在1 mm厚度内（最初不包括天线罩）。对于一般应用，宽带低噪声放大器与天线集成，可以在3至5V下工作，但这可以取消选择作为制造选项，将其转换为无源天线。LNA将使封装增加0.5 mm，但这可以嵌入安装面板以保持1 mm的轮廓（不包括天线罩）。将支持20 dB和45 dB的增益。这种方法将允许在适当小的封装内接收L1、L2和L5信号，天线可以被并入CPRA（相控阵列）。SSTL拥有用于调谐功能测试的消声设备，并拥有能够提供校准天线测量室的合作伙伴。在随后的阶段，SSTL可以制造和测试少量天线，但希望将设计许可证授予大规模产品制造商，如果需要的话，只要SSTL维护用于空间应用的IP。
