Monopole antennas enable multiple M2M applications for Zigbee and ISM Band

San Diego, CA — Pulse, a Technitrol Company, is offering a set of monopole antennas that deliver Zigbee 2.4 GHz and ISM bands 868 MHz, 915 MHz, and 2.4GHz. These antennas are ideal 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.

The antennas 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 comprises 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. Further, 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 mm wide x 1.6 mm long x 1.1 mm high with a weight of 33 mg. It is matched to 2.4 GHz or other frequencies.

The W3000, also compact, measures only 7 mm x 1.6 mm x 1.6 mm and weighs 86 mg. It's used for 2.4 GHz and ISM band 868. With clearance, these antennas measure 66 mm² (11 x 6 mm). Compared to a typical 2.45 GHz FR-4 trace antenna which measures 200 mm² (20 x 10 mm), the company's monopole antennas deliver 67 percent 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 1 0mm x 3.2 mm x 1.5 mm chip with a weight of 240 mg. It uses ISM band 915 so it can be used for designs containing a suitable matching circuit. On the other hand, the W3016 is ideal for ISM band 868 and is 10 mm x 3.2 mm x 4 mm with a weight of 600 mg.

All Pulse monopole antennas are RoHS compliant and fully compatible with surface mount devices.
