1. INTRODUCTION

The Warrior, the revolutionary patent pending PA.710A is a 2G/3G/4G, High Efficiency SMT Ceramic antenna, operating

at 698MHz to 960MHz and 1710MHz to 2690MHz. It uses high grade custom ceramic material and new design

techniques to deliver the highest efficiencies on all bands when mounted on the device’s main PCB. The exceptional

wide-band response means it is the ideal antenna for all LTE applications that also need high efficiency and backward

compatibility for 2G and 3G globally on all lower and upper bands. The PA.710A is delivered on tape and reel and

mounted securely during the device PCB reflow process.

1.1 Key Advantages

1. Highest efficiency in a small size, i.e. 40mm*6mm*5mm. A comparative antenna, for

example metal/FR4/FPC/whip/rod/helix, would have much reduced efficiency in this

configuration due to their different dielectric constants. Very high efficiency antennas are critical

to 3G and 4G devices ability to deliver the stated data-speed rates of systems such as HSPA and

LTE.

2. More resistant to detuning compared to other antenna integrations. If tuning is

required it can be tuned for the device environment using a matching circuit, or other techniques

on the main PCB itself. There is no need for new tooling, thereby saving money if customization

is required.

3. Highly reliable and robust– its predecessors the PA.25A and PA700A antennas are used by

the world’s leading automotive makers in extremely challenging environments. The antenna

meets all temperature and mechanical specs required (vibration, drop tests etc)

4. Easy to integrate. Other antenna designs come in irregular shapes and sizes making them

more difficult to integrate.

5. Surface Mount Technology (Directly On-Board) antenna saves on labor, cable and

connector costs, leads to higher integration yield rates, and reduces losses in transmission.

6. Minimum Transmission and Reception Losses - these are kept to absolute minimum

resulting in much improved OTA (over the air), i.e. TRP (Total Radiated Power)/TIS (Total

Isotropic Radiation), device performance compared to similar efficiency cable and connector

antenna solutions. This means it is an ideal antenna to be used for devices that need to pass for

example USA carrier network approvals

7. RSE Reductions – will help to eliminate radiated spurious emission failures compared to

other antenna technologies as the required layout for the antenna can deliver natural isolation

between the onboard noise and the antenna itself. Also the antenna can be matched better to

the system with the matching circuit function.
