## **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.18 will be more pointed to the remote user.

## **5. Ground Plane Effect**
Three ground setups are used to see the affect of positioning TI.18 close to ground -
1. Small Ground (15 x 9cm) – common size of CPE devices. TI.18 is mounted at the longer edge for testing.
2. Big Ground Edge (45 x 30cm) – 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 (45 x 30cm) – simulate the effect of mounting antenna in a centre of a big ground plane, such as vehicle top.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
