FXP07.07.0100A

SPECIFICATION Part No. : FXP07.07.0100A Product Name : Flexible PCB Penta Band GSM Antenna, 100mm Ø1.13 cable, IPEX connector Feature : Very low profile Penta band GSM Adhesive tape for easy mounting RoHS compliant SPE-11-8-114/C Page 1 of 10 1. Introduction FXP07.07.0100A is a general version of stick-on flexible PCB. It is designed with 100mm 1.13mm coaxial cable and the IPEX connector for easy installation. FXP07.07.0100A is ideal for initial test of FPCB type antenna. 2.

Electrical Property 3.1 Test Setup FXP.07 was design with a cell phone size ground plane (110 x 45 mm) so works the best with this ground plane. Tests were setup to demonstrate its RF properties with this ground plane, in free space and adhere to a plastic. Satimo SG64 3D-chamber is used for radiation and efficiency test with 5% tolerance.

On the underside of the antenna is automotive grade 3m adhesive (glue) for sticking the FXP.07 directly to plastic (e.g. housing). The antenna can be curved around housing but should not be folded sharply Ground connection - this small square pad at the bottom of the FXP.07 can be seen when paper is removed. This should be connected to extra ground or metal to increase efficiency (e.g. allow pad to touch the side of a PCB like the picture above This is the antenna trace or signal feed and should be allowed to be free from the PCB and allowed to exist in free area on non metal area (plastic housing)_ SPE-11-8-114/C Page 4 of 10 z y x Free space antenna setup and Satimo SG64 3D-chamber. z y x FXP.07 places on a plastic in the chamber.

These tests demonstrate the best performance (with the designed ground) and the worst performance (with no ground) possible of FXP.07. Adhere the antenna to a plastic changes the result, particularly in higher frequency bands.
