Five-Band Internal Cellular Antennas Maintain A Low Profile

Employing the company’s ceramic technology, the W3530 multi-hybrid, five-band, internal cellular antenna maintains a very low profile and weight. The antenna works on all four GSM bands (GSM850, EGSM900, PCN1800, and PCS1900) and on the W-CDMA 2100 band. The unit measures only 40 mm x 8 mm x 6 mm and weighs 1.6 g. Its wide return-loss bandwidth allows placement in devices of various sizes. All operating bands are combined to a single feed point for multiband engines. Ceramic and sheet metal are combined in a unique way and use integrated matching circuits. In addition, ceramic’s immunity to the presence of other antennas and to the hand/head effect (electro-magnetic emissions that can affect antenna performance) makes the W3530 well suited for handheld devices with multiple antennas. The company provides customers with detailed antenna implementation guidelines regarding footprints, mechanical aspects, and contacting issues. RoHS-compliant, the antennas start at $3.25 each/10,000. PULSE, A TECHNITROL CO., San Diego, CA. (858) 674-8100.
