Antenna and RF module maker Antenova is shipping its latest module for tiny positioning devices – the Radionova M20047-1. First announced at CES in Las Vegas, this is an active antenna module for GNSS applications in the 1559 to 1609MHz satellite bands using GPS, Glonass, Galileo or Beidou.
 
The module comprises an SMD antenna with built-in active components: an LNA filter and saw to boost antenna performance so designers will not need to add these. They are contained in an FR4 part with low power consumption, measuring 7.0 by 7.0 by 0.9mm and weighing less than 2g.
 
The on-board LNA and filter act to boost the signal to the GNSS processor in environments where there is a restricted view of the sky or where line-of-sight to the horizon is difficult.
 
The UK company has also added an external matching feature to compensate for any de-tuning of the antenna caused by proximity to other components, such as a plastic case or a battery. The clear-out area required by the antenna module is 7.0 by 5.0mm. This, with its size, makes the module suitable for small positioning devices where space on the PCB is tight, for example in wearable devices, asset tracking, sports cameras and equipment, and smart watches.
 
The module is an alternative to firm’s Sinica antenna, part no SR4G008, which it also recommends for accurate positioning.
 
Antenova’s antennas are designed for easy integration. and a datasheet and evaluation kit for the M20047-1 are available. The company also provides engineering support, antenna testing, tuning and integration.
 
Antenova’s range of standard antennas and RF modules are suitable for GSM, CDMA, 3G, 4G, LTE, NB-IoT, GPS, GNSS, wifi, Bluetooth, Zigbee, LPWAN, LoRa, Sigfox, Weightless-P and ISM, for M2M and IoT applications. The company provides design advice and technical support, including custom antenna design, engineering, integration and test services.
