Taoglas SDWA.01 Surface Mount / Patch Multi-band WiFi

Description

• Antenna Type: Surface Mount / Patch
• Frequency: Multi-band WiFi
• Power Gain: 5 dBi
• Connector: SMD
• Application: WiFi / WLAN

The SDWA.01 dual-band SMT ceramic antenna is an embedded, high efficiency, high
peak gain solution for Wi-Fi 802.11n and other ISM band applications which require highspeed
data rates and wide coverage areas. Designed for the 2.4 GHz and 5 GHz bands,
the antenna delivers a peak gain of 3.5 dBi and 4.2 dBi, respectively. The antenna
features excellent efficiency > 70% in both bands. 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 SMT 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.
