Antenna tuning means how well antenna impedance is matched to its chipset. For example a well-tuned 2.4 GHz WiFi antenna will have very low return loss in 2.4- 2.484 GHz, thus ensuring very low reflections with the chipset transceiver.

In this service, we optimize antenna performance on physical prototyping.  All antennas are sensitive to their environment such as plastic metals, near by metals…etc. When the antenna is integrated to the product, its common that its target turnings are slightly off-set from the simulations. Thus, antenna tunings needed to be adjusted to target frequency range either by optimizing matching component values, topology or by slightly changing the physical dimension of the antenna.

Final antenna is always needed to be tuned in its final resting place and with final usage environment, to ensure best RF link possible

Antenna tuning procedure will result in optimal RF performance for the whole product.

We use state-of-the-art Agilent 5071C vector network analyzers with due ECAL kits. We measure the antenna “raw impedance”, then using antenna matching software, we design antenna matching circuit topology and values. We solder appropriate matching components to tune antenna resonance to the target frequency band.

Once, antenna return loss is optimized, we will proceed to antenna passive testing in anechoic chamber, ETS-8050. An antenna anechoic chamber provides a stable, non-reflective environment for antenna tesiting. At CoreIoT Technologies, we have antenna anechoic chamber capable of measuring from 700 MHz to 10 GHz. Measurements below this frequency range is also possible.



CoreIoT will compile a report on the antenna measurements including:
