A uniform field area (UFA) testing apparatus, used for an UFA test, including a testing rack and a plurality of field strength probes. The plurality of field strength probes are mounted on the testing rack. The plurality of field strength probes are positioned on a vertical plane and forms a probe grid array corresponding to the testing points of the UFA test, the grid spacing of the probe grid array corresponds to the distance of the neighboring testing points of the UFA test.

No: 13/718218 Application Filed: December 18, 2012 Assignees: HON HAI PRECISION INDUSTRY CO., LTD. (New Taipei, TW), HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD. (Shenzhen, CN) Claim: 1. A uniform field area (UFA) testing apparatus, comprising: a testing rack; and a plurality of field strength probes, mounted on the testing rack; wherein the plurality of field strength probes are positioned on a vertical plane and forms a probe grid array corresponding to the testing points of the UFA test, the grid spacing of the probe grid array corresponds to the distance of the neighboring testing points of the UFA test. Claim: 2. The UFA testing apparatus of claim 1, wherein the plurality of field strength probes are detachably mounted on the testing rack. Claim: 3. The UFA testing apparatus of claim 1, wherein the testing rack includes a baseboard, two columns, and a plurality of bars, the two columns are mounted on the baseboard and are perpendicular to the baseboard, the plurality of bars are mounted spaced on the two columns at predetermined heights. Claim: 4. The UFA testing apparatus of claim 3, wherein the plurality of bars are equally spaced on the column at a predetermined distance, the distance corresponds to the distance of the neighboring testing points of the UFA test. Claim: 5. The UFA testing apparatus of claim 4, wherein the space between the distal ends of each bar detachably hold a field strength probe, the space between the distal end of the neighboring bars in the same height on different column corresponds to the distance of the neighboring testing points of the UFA test. Claim: 6. The UFA testing apparatus of claim 4, wherein the lowest bars being a predetermined height above the floor. Claim: 7. A UFA testing system, comprising: a UFA testing apparatus, including a testing rack and a plurality of field strength probes mounted on the testing rack; an antenna; a computer, connected to the antenna; a power meter, connected to the UFA testing apparatus; a power amplifier, connected to the power meter; a signal generator, connected to the power amplifier; wherein the plurality of field strength probes are positioned on a vertical plane and form a probe grid array corresponding to the testing points of the UFA test, the antenna is aimed at the probe grid array, the signal generator generates signal in different transmit frequencies, the signal is transmitted to the plurality of field strength probes by the power amplifier, the power meter, and the antenna, the computer analyzes the data read by the plurality of field strength probes in different frequencies and determines whether the UFA has substantially uniformity. Claim: 8. The UFA testing system of claim 7, wherein the antenna aims at the plurality of field strength probes at horizontal polarity and vertical polarity respectively. Claim: 9. The UFA testing system of claim 7, wherein the transmission frequency includes a first frequency band and a second frequency band, when the first frequency band is a high frequency band, the second frequency band is a low frequency band; when the first frequency band is a low frequency band, the second frequency band is a high frequency band. Claim: 10. The UFA testing system of claim 9, wherein the low frequency band with a range of 80 MHz-1000 MHz, the high frequency band with a range of 1 GHz-3 GHz. Claim: 11. The UFA testing system of claim 9, wherein the antenna is spaced from the UFA testing apparatus of a predetermined distance. Claim: 12. A UFA testing method, comprising the following steps: placing a UFA testing apparatus in a UFA, and ensuring a plurality of field strength probes are respectively positioned according to a corresponding the testing point of the UFA; measuring the UFA in a first frequency band; changing an antenna for a UFA test in a second frequency band; measuring the UFA in the second frequency band; determining the testing result. Claim: 13. The UFA testing method of claim 12, the step of measuring the UFA in the first and second frequency band further comprising: transmitting a signal with predetermined antenna polarity to the probe grid array corresponding to the testing points of the UFA test; regulating the transmission frequency, to make one of the field strength probe read a predetermined data, recording the present transmission power and the data read by each field strength probe; increasing the transmission frequency until reaching the upper limit of the frequency band; recording the transmission power corresponding to each frequency point and the data read by each field strength probe; changing the polarity of the signal; repeating the above steps. Claim: 14. The UFA testing method of claim 12, wherein when the first frequency band is a high frequency band, the second frequency band is a low frequency band; when the first frequency band is a low frequency band, the second frequency band is a high frequency band. Claim: 15. The UFA testing method of claim 14, wherein the low frequency band with a range of 80 MHz-1000 MHz, the high frequency band with a range of 1 GHz-3 GHz.
