Embedded GSM Antenna
A flexible PCB gives you an ultra flat shape and the freedom to glue the embedded GSM antenna inside your box, even if it has a rounded shape. This embedded GSM antenna is ideal for use with GSM/3G modules with Assisted GPS functionality on board where only one antenna connection is available. The embedded GSM antenna has been designed in a flexible material with a rectangular form-factor and cable connection for an easy installation. The embedded GSM antenna works on different plastics and thickness.
GSM 3G PIFA Antenna
GSM / 3G PIFA antenna that covers all GSM bands 850, 900, 1800, 1900 and the UMTS 2100 band and offers a very high antenna efficiency
With its ultra small size it fits best for tiny applications like small tracking devices (people, animals, assets), PDA, digital camera, mobile phones or POS
Antenna efficiency
The efficiency of an antenna relates the power transited from M2M module to the antenna and the power radiated or dissipated within the antenna. A high efficiency antenna has most of the power present at the antenna’s input radiated away. A low efficiency antenna has most of the power absorbed as losses within the antenna. [...]
PTRCB Over-the-Air Test
For cellular applications such as GSM or CDMA basic RF performance is measured in terms of the product being able to transmit and receive reliably on a network. The scientific way to measure performance is in an anechoic chamber.
