DESCRIPTION
Walsin Technology Corporation develops a new ceramic embedded antenna specified for 2.4 GHz ISM Band application, as
shown in below “CONSTRUCTION”. Both of Wireless LAN IEEE 802.11b and Bluetooth
TM
typically located on this unlicensed
frequency band which range covers from 2.4GHz to 2.4835GHz. To fulfil the friendly usage for antenna, this antenna has
been designed to a typical 150MHz bandwidth through Walsin’s advanced LTCC (Low Temperature Co-fired Ceramic)
technology and superior product design via 3D EM Simulation Skill.
This antenna has a rectangular ceramic body with a tiny dimension of 5.2x 2.0 x 1.1 mm
3
meet the future SMT automation
and miniaturization requirements on modern portable devices.
