SPECIFICATION Part No. : TI.18.3113 Product Name : 3dBi 868MHz ISM Band Dipole Terminal Antenna, SMA(M) Hinged Connector Feature : High efficiency dipole terminal antenna ROHS compliant SPE-11-8-13/E/ZL Page 1 of 22
1. Introduction TI.18 is high performance 868MHz ISM band dipole omni-directional antenna. The SMA connector is for general purpose used and the hinged design enables the antenna to be positioned at its most suitable angle. For a lot of antenna applications, such as Wi-Fi Hotspot or cellular Pico-cell, the antenna of the operator s device and the antenna of the user s remote device are not on the same horizontal level. So rather than having the usual dipole antenna with dumbbell shape radiation pattern in the E-plane cross-section, we have designed this antenna with butterfly shape radiation pattern. This way, the best radiation direction of TI.19 will be more pointed to the remote user. 2.

. Ground Plane Effect Three ground setups are used to see the affect of positioning TI.18 close to ground - 1. Small Ground (1 x 9cm) common size of CPE devices. TI.18 is mounted at the longer edge for testing. 2. Big Ground Edge (4 x 3cm) simulate the effect of mounting antenna on a base station device. TI.18 is mounted at the centre of the longer edge. 3. Big Ground Centre (4 x 3cm) simulate the effect of mounting antenna in a centre of a big ground plane, such as vehicle top. SPE-11-8-13/E/ZL Page 12 of 22
