This article describes the Ceramic Chip Antennas vs. PCB Trace Antennas (LA76814K). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: LA76814K.

A new white paper has been released comparing ceramic chip antennas and pcb trace antennas. The paper discusses the pros and cons of these two popular antenna types.

The purpose of a trace antenna on a printed circuit board (PCB) is to provide a method of wireless communication. The trace is laminated on thePCB’s surface or, in some cases, the traces can occupy several layers of a multilayer board and vias are used to interconnect the traces on each layer. A ceramic antenna is a separate component that is attached during the final stage in the surface mount process. Pulse Electronics’ article, written by Jouni Lifl?nder, RF designer at Pulse Finland Oy, discusses the advantages and disadvantages of each type of antenna and which antenna best fits specific situations.

“Multi-purpose machine-to-machine devices require a high-quality radio interface that will operate in the Zigbee,ISM, and cellular bands includingLTE, bands which lie between 700 and 2500 MHz. A trace antenna on aPCBis often the first type of interface considered for one of these applications. However, using a ceramic antenna can be a good or even better alternative,” explained Lifl?nder. “In these products, size constraints are more stringent and multiple antennas often need to be placed inside the same device, resulting in the need for high immunity between the antennas. Ceramic antennas enable flexibility in design, overall cost savings in the final product, have fewer problems with interference, and provide improved performance over trace antennas. This paper delves more deeply into these issues.”
