1.Introduction
Taoglas´ 5150-5900 MHz ceramic chip antenna is specifically designed for
Wi-Fi/ WHDMI/ High Bandwidth 5GHz band applications. It is a high efficiency
miniature SMD edge mounted ceramic monopole antenna with small footprint
requirement. This ceramic chip antenna uses the main PCB as its ground plane,
thereby increasing antenna efficiency. It is tuned for different PCB sizes by
simply changing the value of the matching circuit. CA.50 antenna electrical
properties are symmetrical therefore the antenna can be soldered to the board
from either side. At 3.2mm*1.6mm*0.5mm, it is one of the smallest antennas
available worldwide. This antenna is delivered on tape and reel.
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.
