The SDWA.01 SMD ceramic antenna is an embedded, high efficiency, high peak gain solution for Wi-Fi
applications which require high-speed data rates and wide coverage areas. Designed for the 2.4 GHz, 5.8 GHz
and 7.125GHz bands. The antenna covers the newly established Wi-Fi 6 spectrum for future proof design. It
is designed to perform optimally mounted in the corner of a device PCB. Two SDWA.01 antennas can be used
for MIMO applications. The antenna's low profile, at only 1.5mm, allows for use on extremely thin devices
while still maintaining excellent performance characteristics. This antenna is delivered on Tape and Reel for
SMD application.
Many module manufacturers specify peak gain limits for any antennas that are to be connected to that
module. Those peak gain limits are based on free-space conditions. In practice, the peak gain of an antenna
tested in free space can degrade by at least 1 or 2dBi when put inside a device. So ideally you should go for
a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect,
giving you better performance.
Upon testing of any of our antennas with your device and a selection of appropriate layout, integration
technique, or cable, Taoglas can make sure any of our antennas’ peak gain will be below the peak gain limits.
Taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly
show it complying with the peak gain limits, so you can be assured you are meeting regulatory requirements
for that module.
For example, a module manufacturer may state that the antenna must have less than 2dBi peak gain, but
you don’t need to select an embedded antenna that has a peak gain of less than 2dBi in free space. This will
give you a less optimized solution. It is better to go for a slightly higher free-space peak gain of 3dBi or more
if available. Once that antenna gets integrated into your device, performance will degrade below this 2dBi
peak gain due to the effects of GND plane, surrounding components, and device housing. If you want to be
absolutely sure, contact Taoglas and we will test. Choosing a Taoglas antenna with a higher peak gain than
what is specified by the module manufacturer and enlisting our help will ensure you are getting the best
performance possible without exceeding the peak gain limits.

Like all antennas, surrounding components, enclosures, and changes to the GND plane dimensions can alter
performance. A pi-matching network like the one shown below is required in case adjustments need to be made.
Make S1 a zero ohm resistor and leave S2 and S3 unpopulated when building first prototypes. These components
will likely need to be adjusted upon integration to provide the best match between the antenna and transmission
line. The additional zero ohm resistor in the diagram is needed for the ability to solder down a coax pigtail to make
measurements with a vector network analyzer.

1. Time shown in the above figures is measured from the point when chip surface
reaches temperature.
2. Temperature difference in high temperature part should be within 110°C.
3. After soldering, do not force cool, allow the parts to cool gradually.
*General attention to soldering:
● High soldering temperatures and long soldering times can cause leaching of the termination, decrease
in adherence strength, and the change of characteristic may occur.
● for soldering, please refer to the soldering curves above. However, please
Keep exposure to temperatures exceeding 200°C to under 50 seconds.
● please use a mild flux (containing less than 0.2wt% Cl). Also, if the flux is water soluble, be sure to wash
thoroughly to remove any residue from the underside of components that could affect resistance.
Cleaning:
When using ultrasonic cleaning, the board may resonate if the output power is too high.
Since this vibration can cause cracking or a decrease in the adherence of the termination, we
recommend that you use the conditions below.
Frequency: 40 kHz max.
Output power: 20W/Iiter
Cleaning time: 5minutes max.
