1. ANTENNA DESCRIPTION

The Micro Reach XtendTM chip antenna is a very small size and low cost antenna that combines

reduced clearance area required within the customer PCB with its high performance and

integration flexibility. This makes it ideal for small consumer electronics devices such as small

wireless headsets and highly integrated multifunction mobile handsets.

3.2. MATCHING NETWORK

The specs of a Fractus Antennas standard antenna are measured in their evaluation board,which

is an ideal case. In a real design, components nearby the antenna, LCD’s, batteries, covers,

connectors, etc affect the antenna performance. This is the reason why it is highly recommended

placing pads compatible with 0402 and 0603 SMD components for a PI matching network as

close as possible to the antenna feeding point. Doit in the ground plane area, not in the clearance

area. This is a degree of freedom to tune the antenna once the design is finished and taking into

account all elements of the system (batteries, displays, covers, etc).

Please notice that different devices with different ground planes and different components nearby

the Micro Reach Xtend™ chip antennamay needa different matching network. To ensure optimal

results, the use of high Q and tight tolerance components is highly recommended (Murata

components). If you need assistance to design your matching network beyond this application

Track design service, you will get your chip antenna design including a custom matching network
