Miniature ceramic RF chip antennas are commonly used in 2.4 GHz wireless applications such as Bluetooth, WiFi, and ZigBee because they are low cost and small in physical size. Johanson Technology’s 2450AT42E010xx chip antennas have these features, but also provide another unique benefit. The antennas were specifically designed for applications where metal is directly underneath the antenna and is actually required for the antenna to perform optimally. The benefit of this characteristic is that the performance of the antenna will not be negatively affected by proximity to a coin cell battery or display containing metal. This allows smaller PCB designs and provides flexibility in the form factor and placement of the end product.
