Units: mm *Line width should be designed to provide 50 impedance matching characteristics. It is recommended that the designer leave available Metal Clearance area slots for ap (or shunt-series-shunt) network. The GND 50 Feed antenna matching network values are used when line antenna is monted on Johanson s evaluation board. The matching values on clinet s PCB will be different. 1 pF Go to:High Frequency Ceramic Solution 2.38GHz / 2.45GHz / 2.6GHz Wideband SMD Chip Antenna P/N 2500AT44M0400 Designed for: BAN, Bluetooth, 802.11, WLAN, Zigbee, Propietary Protocol, ISM, Smart Energy, WiMax Page 2 of 9 Detail Specification: 5/24/2013 Layout 1 example (units in mm) Matching circuits Antenna Ground 20 50 Feed line (can be shortened as No Ground 40 12 Orderable EVB p/n: 2500AT44M0400-EB1SMA Return Loss - with Matching Circuits Johanson Technology, Inc. reserves the right to make design changes without notice.
