Embodiment Construction

[0036] At first, the theoretical basis of the present invention is described, and the electromagnetic field equation of the current element is provided earlier and an auxiliary explanation is made:

[0037] The current element is one of the basic radiation units (also known as the basic electric vibrator or electric dipole, which is a short wire carrying a high-frequency current with equal and different charges at both ends, and the diameter of the wire is d Figure 8 Shown:

[0038] The magnetic and electric field equations of the current element are as follows:

[0039] H r = 0 H θ = 0 H φ = j Il 2 ...

Abstract

The invention relates to a mobile terminal radiation continuous harassment index testing method and the system thereof. The system includes a shielding room 21, an integrated tester 31, a spectrum analyzer 51, and a small electromagnetic wave receiving probe 52. The method includes the steps of testing the shielding interference in the shielding room 21; setting up the communication between the integrated tester and the mobile terminal, and dictating the mobile terminal to transmit at the maximum power; using the spectrum analyzer and the connected small receiving probe 52 to scan the radiation continuous harassment energy collected by the mobile terminal; calculating the energy level margins among all the harassment frequency points and a main transmitting frequency point, and determining a threshold according to an index test, judging whether the index requirement is met referring to the tolerance. The method and the system thereof use the shielding room to replace the microwave no-reflection darkroom, uses the near-field / far-field conversion relationship to make the simulation test ready and provide circumstance for a product before the real radiation continuous harassment test. The invention can save cost, provide convenience, and shorten development period.

Description

technical field [0001] The invention relates to a mobile terminal testing technology, in particular to a mobile terminal radiation continuous disturbance index testing method and system thereof. Background technique [0002] At present, the number of digital mobile subscribers in the world has reached 1.3 billion, and with the issuance of 3G licenses in China, this number is expected to double in the next few years. It is predicted that in 2008, the global communication industry will present a huge market of up to 2 billion mobile users. [0003] Global mobile services and applications are growing in three main directions: voice, multimedia and enterprise applications. Mobile data services will have an increasing share in the mobile market. As of September 2003, the number of global mobile data service users reached 100 million, accounting for 7.7% of the world's 1.29 billion mobile users, an increase of 14% compared with the statistics in June 2003. By 2007, the proporti...
