Low Cost 2.4 GHz Weatherproof Antennas Targets M2M Apps

June 16, 2010

Since Pat has brought up the topic of antennas with his blog about this component's "five minutes of fame" sharing the stage with Steve Jobs as the Apple founder introduced the new 4G iPhone, I thought I would share the following product release that came across my desk today as well. After all, any RF/microwave device targeting Smart grid applications has as much of a cool factor as any in the latest smartphone. Well, maybe not. But helping to save the planet by being green gets my seal of approval.

Pulse, a Technitrol Company (NYSE: TNL), a manufacturer of electronic components and subassembly design and manufacturing, introduces its new low cost, weatherproof antennas for 2.4 GHz devices used in industrial, smart grid metering, security, broadband access, and other machine-to-machine(M2M) applications. These robust, high-efficiency, compact antennas meet Bluetooth, WLAN, WiFi, IEEE 802.11b/g, ZigBee IEEE 802.15.4, and 2.4 GHz ISM band system standards.

Pulse's W5001, W5010, and W5011 antennas function in ruggedized conditions, offering IP65 water ingress protection in accordance with international standard IEC 60529, UV protection, and the ability to withstand 100 mph wind loading. They have a maximum gain of 1.5 dBi in the 2,400 to 2,500 MHz range, an efficiency of 70%, and an operating temperature range of -40°C to 85°C. The antennas have a small footprint and low profile, measuring only 128mm x 18mm.

Pulse's W5001, W5010, and W5011 antennas are available in three SMA connector configurations: fixed right angle, straight SMA, and RP-SMA. They are packaged in quantities of 20 pieces per bag.
