The W1900 series of stubby external antennas are more than 50% efficient in all bands and are less than 50mm tall, providing a reliable wireless M2M connection in a small form factor. The stubby antennas cover frequency bands 824-960 and 1710-1990 MHz for all widely used cellular bands for 2G, 2.5G and 3G applications. They have a peak gain of 1 dBi in the 824-960 MHz range, 2 dBi in the 1710-1990 MHz range, and 2.5 dBi in the 1920-2170 MHz range, with an impedance of 50 Ohms. These antennas come in two configurations: the W1900 and W1902 are straight antennas for connection to the top of a device or modem while the W1910 and W1911 have a right angle connection for mounting on the side of a product.
The W1920 series of cellular, penta-band blade antennas with cable and SMA connectors are cost-effective M2M antennas for the industrial marketplace. Antennas in this series deliver at least 50% radiated efficiency in all frequency bands in which they operate, while still providing voltage standing wave ratio (VSWR) figures of 1.5 decibels (dB). The blade antennas come in two configurations, the W1920G0915, which has a three-foot cable, and the W1920G3658, with a 12-foot cable. Measuring 110 x 22 x 5 millimeters and weighing 29 grams with the shorter cable, this is the smallest penta-band blade antenna capable of operating at 50% efficiency in every frequency band. Other specifications include a gain of minimum 1 decibel isotropic (dBi), a nominal impedance of 50 , an omni-directional radiation pattern in the horizontal plane, vertical polarization, and a power rating of 3 watts.
The W3538 series of penta-band standalone PCB antennas features peak efficiency of more than 50% and comes with a variety of different connectors, depending on the model. Designed for connection to global cellular networks at 850/900/1800/1900/2100 MHz, this small form factor PCB measures only 40 x 15 x 0.7mm and can be mounted simply inside an enclosure with adhesive tape. Versions with cable lengths up to 300mm are available, with custom cable lengths on request.
