Penta-band antennas for M2M applications manufactured by Pulse are available from Solid State Supplies as blade or standalone antennas.

The W1900 series of penta-band blade antennas are less than 50mm tall.

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. 

The W3538 series of penta-band standalone PCB antennas are designed for connection to cellular networks at 850, 900, 1800, 1900 and 2100MHz.

The  PCB measures 40 x 15 x 0.7mm and can be mounted simply inside an enclosure with adhesive tape.
