1.Introduction

This revolutionary patent pending Samurai PA.700.J is a 2G/3G/4G high efficiency SMD ceramic

antenna operating at 700MHz to 960MHz, 1400MHz to 2600MHz to cover all LTE frequency

bands applied in Japan. It uses high grade ceramics to deliver the highest efficiencies on all

bands on the shortest device ground-plane lengths possible. The exceptional wide-band

response means it covers all standardly used operation bands around the globe.

1.1 Key Advantages

1. Highest efficiency in small size 40mm*6mm*5mm. A comparative metal, FR4, FPC, whip, rod,

helix antenna, would have much more reduced efficiency in this configuration for the same size

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. There is no

need for new tooling, thereby saving money if customization is required.

3. Highly reliable and robust– its predecessor the PA.25 antenna is used by the world’s leading

auto makers in extremely challenging environments. The antenna meets all temperature and

mechanical specs required (vibration, drop tests etc)

4. Rectangular shape - Easy to integrate. Other antenna designs come in irregular shapes and

sizes making them hard to integrate.

5. SMD (On-Board) antenna saves on labor, cable and connector costs, leads to higher

integration yield rates, and reduces losses in transmission.

6. It mounts directly on edge of device main-board.

7. Transmission losses are kept to absolute minimum resulting in much improved over the air

(OTA) TRP (Total Radiated Power) / TIS (Total Isotropic Radiation) device performance

compared to similar efficiency cable and connector antenna solutions.
