FXP400070100A Datasheet, PDF (6/18 Pages) List of Unclassifed Manufacturers – High Efficiency Ultra Wide-Band Antenna with 100mm 1.13 cable IPEX MHF(U.FL)

4.0 S11 Measurement
Six different ground plane configurations have been tested:
1) Orthogonally displaced on the edge of an 80 x 40 mm² groundplane;
2) Co-planarly displaced on the edge of an 80 x 40 mm² groundplane;
3) Orthogonally displaced on the edge of a 100 x 40 mm² groundplane;
4) Co-planarly displaced on the edge of a 100 x 40 mm² groundplane;
5) Orthogonally displaced on the edge of a 200 x 200 mm² groundplane;
6) Co-planarly displaced on the edge of a 200 x 200 mm² groundplane.
The antenna presents a versatile behaviour and offers a good impedance matching and radiation
performance for different grounding solutions. In particular, it offers 6 dB return loss bands (5 dB at the
edge) over the ranges 690 – 960 MHz and 1.71 – 2.69 GHz (LTE bands) for the configurations 4, 5 and 6.
But for the configurations 1 and 2 its performance is very close to LTE requirements.
This suggests that this antenna can be allocated into small devises either orthogonally or co-planarly
displaced at the edge of the chipboard. The co-planar configuration might be suitable for small (~ 80/100
x 40 x 33 mm³) and low-profile devises.
