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
