ntenna tuning means how well antenna impedance is matched to its chipset. For example, a well-tuned 2.4 GHz WiFi antenna will have shallow return loss in 2.4- 2.484 GHz, thus ensuring shallow 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, nearby metals…etc. When the antenna is integrated into the product, it’s common that its target turnings are slightly off-set from the simulations. Thus, antenna tunings needed to be adjusted to the target frequency range either by optimizing matching component values, topology, or slightly changing the antenna’s physical dimension.
