SPE-12-8-051/C/ZL Page 1 of 11 SPECIFICATION Part No. : FXP07.09.0100A Product Name : Flexible PCB Penta Band GSM Antenna, 100mm 1.13cable, right angle MMCX connector Feature : Very low profile penta-band GSM Adhesive tape for easy mounting RoHS compliant
SPE-12-8-051/C/ZL Page 2 of 11 1. Introduction FXP.07 is a general version of stick-on flexible PCB GSM penta-band antenna. It is designed with a cellphone size ground plane so works the best with devices of similar size or bigger. This low profile and conformable antenna can be easily fitted into any housing for plug-and-play application. 2.

2.1 Mounting instructions and ground-plane connection
Peel back 3m paper. 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)_

3.1 Test Setup
FXP.07 was designed with a cell-phone size ground plane (110 x 45 mm). Tests were setup to demonstrate its RF properties with this ground plane, in free space and adhered to a plastic box to simulate a typical application device. Satimo SG64 3D-chamber is used for radiation and efficiency test with 5% tolerance. Satimo SG64 3D-chamber and antenna setup reference. z y x

3.2 Radiation Pattern
FXP.07 with original ground plane This ground plane is what FXP.07 is originally designed for. So the test result can be treated as a bench mark for this antenna. x-y plane x-z plane
SPE-12-8-051/C/ZL Page 6 of 11 FXP.07 in free space Miniature antenna needs a ground plane for radiation. FXP.07 tested with no ground plane present the extreme cases of the antenna performance. x-y plane x-z plane
SPE-12-8-051/C/ZL Page 7 of 11 FXP.07 adhere on plastic Majority of the GSM devices is made with plastic housing. This test demonstrate the effects of FXP.07 adhere on a piece of plastic. Compare the result of FXP.07 in free space with and without adhering on a piece of plastic, the plastic mainly degrade the performance of GSM1850MHz band. x-y plane x-z plane
SPE-12-8-051/C/ZL Page 8 of 11 FXP.07 with the ground plane adhere on plastic box More often, FXP.07 is attached to a piece of ground place and packed in a plastic box. This test try to simulate a typical situation when FXP.07 is attached to a piece of PCB, with other piece in a device. x-y plane x-z plane

These tests demonstrate the best performance (with the designed ground) and the worst performance (with no ground) possible of FXP.07.
