Pulse Monopole Antennas Enable Multiple M2M Applications

Pulse Electronics, a worldwide leader in electronic component and subassembly design and manufacturing, announces its new set of monopole antennas that deliver Zigbee 2.4 gigahertz (GHz) and ISM bands 868 megahertz (MHz), 915 MHz, and 2.4GHz. These antennas are excellent alternatives to using trace antennas because they occupy very little printed circuit board space while maintaining their key properties regardless of changes to the board. They provide a high-quality radio interface for multi-purpose machine-to-machine (M2M) devices and applications such as data loggers, remote control, tracking, monitoring, Smart Grid, automated meter reading (AMR), tags, remote keyless entry, industrial, metering, security, automation, and point-of-sale (POS).

The monopole family of ceramic antennas consists of the W3000, W3014, W3016, and W3043. Due to their small size they are ideally suited to solutions where PCB size is limited for the antenna. Compared to a PCB antenna, the high temperature ceramic (HTC) material used in the monopole family means they detune less due to human tissue proximity or device mechanics, making them an ideal choice for hand-held or body worn products. These antennas can be used for multiple functions because their operating frequencies can be changed simply by implementing different matching circuits.

The smallest antenna is the W3043, at 3.2 millimeters (mm) wide x 1.6mm long x 1.1mm high with a weight of 33 milligrams (mg). It is matched to 2.4 GHz or other frequencies.

The W3000, also compact, measures only 7mm x 1.6mm x 1.6mm and weighs 86mg. It's used for 2.4 GHz and ISM band 868. With clearance, these antennas measure 66mm2 (11 x 6mm). Compared to a typical 2.45 GHz FR-4 trace antenna which measures 200mm2 (20 x 10mm).

Pulse’s monopole antennas deliver 67% more board space. Thus a smaller device can be designed or space freed up for other components, and PCB costs are reduced.

The W3014 is a 10mm x 3.2mm x 1.5mm chip with a weight of 240mg. It uses ISM band 915 so it can be used for designs containing a suitable matching circuit. The W3016 is ideal for ISM band 868 and is 10mm x 3.2mm x 4mm with a weight of 600mg.

“With so many emerging applications in the M2M sector, designers need an antenna solution which accommodates different ground plane sizes and product dimensions,” said Elaine Baxter, marketing manager, Pulse Wireless Devices Antenna Division. "Pulse 's new range of ZigBee and ISM band ceramic monopole antennas offers a comprehensive and flexible portfolio which can be matched to the majority of M2M applications. They provide more reliability and higher performance than traditional trace antennas used on the PCB.”

All Pulse monopole antennas are RoHS compliant and fully compatible with surface mount devices. They are easy to implement and come with Pulse's worldwide technical support. The antennas are packaged in tape-and-reel. Prices range from $0.25 to $0.55 and may vary according to destination and order configuration. Additional information is available on datasheets W3000, W3014, W3016, W3043 or check out the full range of M2M Internal Antenna Products at the Pulse Antenna Applications section.
