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. Introduction Introduction 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. Introduction Introduction 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.

Antenna Radiation Patterns3.Antenna 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 Characteristics 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 with a vector network analyzer. 4.measurements Antenna Radiation Patterns Antenna 4.

Time shown in the above figures is measured from the point when chip surface Antenna Radiation Patterns3. Antenna reaches temperature. Temperature difference in high temperature part should be within 110°C. After soldering, do not force cool, allow the parts to cool gradually. Characteristics *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. 4. Antenna Radiation Patterns Cleaning: using ultrasonic cleaning, the boardPatterns may resonate if the output power is too high. 4.When Antenna Radiation 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. 4. Antenna Radiation Patterns 4. Antenna Radiation Patterns3.Antenna Characteristics 8. Packaging 4. 6.
