page 2 of 15 this revolutionary patent pending pa.700j is a 2g/3g/4g high effciency 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 effciencies 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. highest effciency in a small size, i.e. 40mm*6mm*5mm. a comparative metal, fr4, fpc, whip, rod, helix antenna, would have much more reduced effciency in this confguration for the same size due to their different dielectric constants. very high effciency 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 worlds 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 effciency cable and connector antenna solutions. 8. reductions in probability of radiated spurious emissions compared to other antenna technologies are observed when using the pa.700j and strictly following this application note layout 9. achieves moderate to high gain in both vertical and horizontal polarization planes this feature is very useful in certain wireless communications where the antenna orientation is not fxed and the refections or multipath signals may be present from any plane. in those cases the important parameter to be considered is the total feld strength, which is the vector sum of the signal from the horizontal and vertical polarization planes at any instant in time. 1. introduction 1.1 key advantages lte bands (japan) frequency 1 2100 1920~2170mhz 6 800 830~885mhz 8 900 880~960mhz 9 1700 1749~1880mhz 11 1500 1427~1496mhz 18 800 815~875mhz 19 800 832~889mhz 21 1500 1447~1510mhz 41 2500 2496~2690mhz spe-12-8-017/d/ez |
