Tiny Dual-Band Microwave Antenna Is In Tune With WLAN Equipment

Antennas have become increasingly important in the wireless world, with more and more products embedding wireless capability for convenience and portability. Designers crave an extremely small antenna with good response in all directions, a desire that wireless local-area network (WLAN) equipment designers may now have fulfilled. The MAC2450A5362AAE dual band dielectric chip antenna operates with two center frequencies of 2450 and 5362 MHz. It provides VSWR = 2 bandwidths of 2400 to 2500 MHz and 4900 to 5862 MHz. This linearly polarized antenna provides a 4.4-dBi gain at 2450 MHz and 0.8-dBi gain at 5362 MHz. It measures only 11.8 by 2.5 by 0.7 mm and weighs 0.09 grams. Engineering samples are available now. It costs $0.40 in 1 million-unit quantities.
