PCB Antenna Picks Up Five Cell Bands

Model W3538B0200 is a penta-band antenna from Pulse Engineering, a Technitrol Company, that is not dependent upon ground plane. As a result, the printed-circuit-board (PCB) antenna can be made large or small, depending upon the requirements of an application. For example, antennas as small as 40 x 15 x 0.7 mm deliver as much as 80-percent efficiency. The antenna provides an interface to cellular networks for use in such applications as point-of-sales terminals, credit-card readers, data loggers, automated meter readers, and industrial communications systems.

According to Elaine Baxter, Marketing Manager for the Pulse Antenna Division, "Pulse is responding to the need for a stand-alone antenna that is ground-plane independent to help our M2M customers achieve fast turnaround in their designs while still meeting performance excellence. This antenna provides the greatest efficiency available for an antenna this small." The antenna operates over five frequency bands covering 824 to 894 MHz, 880 to 960 MHz, 1710 to 1880 MHz, 1850 to 1990 MHz, and 1920 to 2170 MHz with minimum efficiency of 50 percent. It features impedance of 50 Ohms and return loss of 6 dB.
