Abstract
The present invention relates to an antenna testing method which comprises the following steps: step one, a network analyzer, a reference antenna, a non-metal box, and an antenna to be tested are selected; the network analyzer is provided with a first port and a second port; step two, the non-metal box is provided with a first receiving part and a second receiving part; step three, the reference antenna and the antenna to be tested are respectively inserted into the corresponding first receiving part and the corresponding second receiving part; step four: the reference antenna is connected with the first port of the network analyzer; the antenna to be tested is connected with the second port of the network analyzer; step five: the first port of the network analyzer emits reference signal transmitted to the reference antenna; the received signals are radiated by the reference antenna; the antenna to be tested inputs the received signals to the second port of the network analyzer, and after the network analyzer contrast the gain loss of the two ports and the predetermined gain decrease, the present invention can obtain whether the antenna to be tested conforms to requirements. After the present invention makes use of the combination of the matched device of the reference antenna and the network analyzer, the present invention can not only effectively enhance the testing quality of the antenna, but also enhance the detection efficiency of the antenna.
Description
[technical field]
The invention relates to a kind of antenna test method, especially refer to a kind of antenna test method of measuring antenna gain.
[background technology]
The check system of existing antenna, be to utilize network analyzer to detect the voltage standing wave(VSW) ratio of antenna, but the same day is traditional thread binding when going in the electronic equipment owing to can produce and insert loss and feeder loss etc., so only the satisfactory antenna of voltage standing wave(VSW) ratio in use its yield value not necessarily just meet the requirements, therefore still can omission defective products antenna.
Antenna body under free state be fixed on voltage standing wave ratio (VSWR) in the electronic equipment can be variant and voltage standing wave ratio (VSWR) only be the size of measuring-signal resilience, for transmission line loss when too big, the verification the verifying results of this method do not match and resilient energy has a little energy turns back to network analyzer for antenna impedance, so can not effectively be guaranteed the quality of antenna.
[summary of the invention]
The purpose of this invention is to provide a kind of equipment combination that utilizes reference antenna to match, can effectively improve the antenna test method of antenna measurement quality with network analyzer.
Antenna test method of the present invention may further comprise the steps: the first step: choose a network analyzer, a reference antenna, a nonmetal box and an antenna to be measured; Second step: on nonmetal box, be provided with first and second resettlement section; The 3rd step: reference antenna and antenna to be measured are inserted respectively in first and second resettlement section; The 4th step: reference antenna is linked to each other with first port of network analyzer, and antenna to be measured links to each other with second port of network analyzer; The 5th step: send reference signal transmission to reference antenna from first port of network analyzer, by reference antenna the signal radiation that is received is gone out again, antenna to be measured is second port of the signal fan-in network analyser that received, network analyzer again with the gain loss of two-port with default gain decrease contrast and then draw antenna to be measured and whether meet the requirements.
Compared with prior art, antenna test method advantage of the present invention is: need not to increase in addition antenna measurement equipment, only need reference antenna of many preparations to match with existing network analyzer and get final product.By with the loss of reference antenna and antenna gain value to be measured and default yield value decrease to recently judging the performance of antenna to be measured, guarantee the quality of antenna with this.
