SPE-23-8-182-A 

The Taoglas Warrior PA.500.A has been designed for use on cellular Band 28 for IoT device applications that utilize this band. The PA.500.A has strong performance at a difficult frequency – it is a specific band 28 antenna for IoT applications. 

The PA.500 has been designed to have no clearance area to make integration easier for customers who may have difficulty integrating a different type of antenna which will not perform well at band 28. 

In past years band 28 was for analogue TV transmission in Australia, New Zealand, and some Asia-Pacific areas. It is now the main Australian 4G band due to redefined spectrum usage. 

Typical Applications include: 

- Compact IoT Sensors 

- Tablets and Smartphones 

- Telematics and Tracking

## Antenna Integration 

Whatever the size of the PCB, the antenna should ideally be placed on the PCB’s shortest side, to take advantage of the ground plane. Optimized matching components can be placed as shown. 

## PCB Layout 

The footprint on the PCB must meet the antenna specification. An example of the PCB layout shows the antenna footprint without clearance.
