Total average radiated efficiency on PCB feature on "Mounting Considerations 1" ( orderable EVB p/n: 2450AT42E0100-EB1SMA) is ~30%
This antenna was designed in mind for small coin cell, wearable, IoT, 2.4 BLE, 802.11, ISM, Zigbee, etc. applications in
close-range networks where metal or a battery/display covers the entire length or side of the PCB or encasement must be
present directly under the antenna and there's no room for usual/typical antenna metal clearance.
This antenna is specifically designed for PCBs that have 0.5-1mm of total thickness

Component values of matching circuit will be different, depending on PCB layout, but the matching circuit’s type has to be “Series-Shunt-Shunt”
shown as above
*Line width should be designed to match 50ohm characteristic impedance, depending on PCB material and thickness., A coplanar waveguide
trace is recommended for best results.
For this particular antenna It is recommended that the designer leave available slots for a shunt-shunt-series network, even if all slots won't be
used, this will prepare the PCB for the unpredictable final mass production version of the matching circuit. The antenna matching network values
above are used when antenna is mounted on Johanson's evaluation board. The matching values on client’s PCB will be different.

The designer should not be highly concerned of the fact that the antenna only demonstrates a -5dB
S11 level at the band edges. The antenna has sufficient gain at the band edges to satisfy the
applications and uses a high dielectric constant ceramic giving it some detuning resilience to
capacitivel loading effects. This antenna is designed for close proximity applications such as the
ones mentioned on page 1.

How To Choose The Correct Antenna Variant
We offer 2 other resonating variants of this antenna since the antenna's efficiency is largely affected by the thickness of the
PCB's substrate. This allows a more robist design to fit your PCB. The disparity between antenna variations are internal
only; variations are identical in dimension and solder footprint.
Refer to the diagram below to understand what is meant by substrate thickness.
Substrate Thickness (H)
For PCBs consisting of multiple layers, the thickness (H) is limited only to the metal layer immediately below 'Top Metal Layer.'
The below plot demonstrates the effect that substrate thickness has on the antenna's performance.

As you can see, there is a direct correlation between substrate thickness (H) and the resonant frequency. This is, in part,
due to the natural capacitive loading effect and resonating frequency of the PCB itself. Our antenna variants were
developed to counter this effect.
Note: "H" substrate thickness of <0.25mm (10mil) is not recommended. The component will still work and radiate, just not
optimally.

We encourage you to use a relatively thick dielectric layer below antenna, as we have seen a direct
correlation between substrate thickness and antenna performance.
Note: "H" substrate thickness of <0.25mm (10mil) is not recommended. The component will still work and
radiate, just not optimally.
