[0031] Example 1
[0032] like Figure 1 As shown, the first aspect of the present application provides a high-field strength test system based on a high-gain antenna. The test system includes a radiation source generating device and a test component. The radiation source generating device includes: a signal source for generating an electrical signal of a specific frequency; a power amplifier for amplifying the electrical signal to a desired level; a high-gain radiating antenna for converting the amplified electrical signal into an electromagnetic wave and controlling the energy of the electromagnetic wave to focus in a specific direction to increase the electric field strength in the specific direction; the test component includes: a receiving antenna for capturing the electromagnetic wave radiated by the high-gain radiating antenna at a predetermined position and converting the electromagnetic wave into an electrical signal to be measured; an analyzing device for analyzing the electrical signal to be measured to measure the electric field strength at the predetermined position. The analyzing device includes: an attenuator for attenuating the electrical signal to be measured to within the test range of a field strength meter; and a field strength meter for calculating the electric field strength at the predetermined position according to a preset field strength calculation formula.
[0033] In this embodiment, the five main parts of the test system are mainly described, namely the power amplifier, high-gain radiating antenna, receiving antenna, attenuator and field strength meter. Figure 1 As shown, the power amplifier and high-gain radiating antenna Ant1 are used to generate a sufficiently large electric field strength in the radiation link; the receiving antenna Ant2, the attenuator and the field strength meter are used to measure the field strength value of the large field strength exceeding the range of the field strength meter.
[0034] The relationship between the field strength E and the power density S is connected by the free space wave impedance η0, and the formula is:
[0035]
[0036] Where C is the correction coefficient, and the free space wave impedance η0 = 120π ≈ 377Ω.
[0037] Power density S is the radiated power P in free space by a high-gain radiating antenna t , radiation gain G t It is determined by the electromagnetic wave transmission distance d and follows the Friis formula:
[0038]
[0039] Substitute S into the field strength formula (1-1):
[0040]
[0041] The field strength formula shows that the radiated power and radiation gain of a high-gain radiating antenna directly affect the field strength along the radiating link, while the output power of the power amplifier determines the power radiated by the antenna. However, the high-power power amplifiers currently available on the market are very expensive.
[0042] Depend on Figure 3 As shown in the figure, when the radiation gain of the high-gain radiating antenna is fixed at 15dBi, the radiation field strength value brought about by increasing the output power of the power amplifier is limited. Figure 2 As shown in the figure, when the power amplifier output power is fixed at 225W, increasing the radiation gain of the high-gain radiating antenna significantly improves the radiation field strength. This shows that when the radiation field strength needs to be increased, increasing the radiation gain of the high-gain radiating antenna can save more testing costs than increasing the power amplifier output power. Therefore, this test system uses a relatively low-cost high-gain antenna to increase the field strength on the radiation link. Therefore, using a conventional power amplifier and high-gain radiating antenna Ant1 can create a radiation source that can generate a large field strength on the radiation link.
[0043] Further, from Figure 2 As shown in the figure, when the amplifier output power is fixed at 225W, a radiating antenna with a radiation gain of 22dBi can achieve a field strength of 1468.72V / m at a distance of 1m along the link, while a radiating antenna with a radiation gain of 30dBi can achieve a field strength of 3700V / m. However, the test range of typical field strength meters is generally less than 1000V / m, making them unable to directly measure the electric field strength at the link location. Therefore, this system incorporates an attenuator between receiving antenna Ant2 and the field strength meter. This attenuates the received signal from receiving antenna Ant2 by a factor of n, bringing the corresponding field strength value within the meter's range. The resulting field strength value is then amplified by a factor of n to determine the electric field strength at the link location where receiving antenna Ant2 is located. Therefore, using receiving antenna Ant2, the attenuator, and a conventional field strength meter, it is possible to measure electric field strengths far beyond the instrument's range.
[0044] Specifically, the electric field strength meter can calculate the electric field strength at the target location based on the following field strength calculation formula:
[0045]
[0046] In formula (1), E represents the electric field strength, P r represents the received power of the receiving antenna, η0 represents the free space wave impedance, G r Indicates the gain of the receiving antenna.
[0047] Example 2
[0048] This embodiment provides a high-field strength test method based on a high-gain antenna, which can be used to verify the effectiveness of the test system in Example 1. The test method includes:
[0049] S1. Set the radiation power of the high-gain radiating antenna to P t , the radiation gain is G t , control the high-gain radiating antenna to radiate electromagnetic waves;
[0050] S2. Capturing electromagnetic waves at a distance d from the high-gain radiating antenna, converting the electromagnetic waves into electrical signals to be measured, and measuring the electric field strength E at the distance d from the high-gain radiating antenna based on the electrical signals to be measured;
[0051] S3, using the control variable method, repeat the above steps S1 to S2, and record multiple sets of variables and result data; the variable is the radiation power P of the high-gain radiating antenna. t , radiation gain G t and the electromagnetic wave transmission distance d, the result is the electric field strength E;
[0052] S4. Based on the data obtained in step S3, verify the radiation power P of the high-gain radiating antenna t , radiation gain G t And whether the inference calculation formula between the electromagnetic wave transmission distance d and the electric field strength E is correct;
[0053] S5. If correct, execute the first test plan or the second test plan based on the inference calculation formula.
[0054] Specifically, the inference calculation formula is (see (1-1) to (1-3) in Example 1 for details):
[0055]
[0056] In formula (2), E represents the electric field strength, P t Represents the radiated power of the high-gain antenna, G t represents the radiation gain of the high-gain antenna, C represents the correction factor, and d represents the propagation distance of the electromagnetic wave.
[0057] Specifically, in step S4, the radiation power P of the high-gain radiation antenna is verified. t , radiation gain G t and whether the inference calculation formula between the electromagnetic wave transmission distance d and the electric field strength E is correct, including: calculating the values of the correction coefficients respectively according to the multiple groups of variables and result data obtained in step S3, if the standard deviation of the multiple correction coefficients obtained by calculation is lower than the threshold value (for example, 0.5), then the inference calculation formula is correct, otherwise it is incorrect; wherein, if the inference calculation formula is correct, the value of C in formula (2) takes the average value of the multiple correction coefficients.
[0058] For example, in order to verify whether the inferred calculation formula of the relationship between antenna gain and radiation field strength is correct, the following CST simulation verification is performed on the horn antenna (high-gain radiation antenna) at different distances in the far field. Figure 4 As shown, the working frequency band of the antenna is 5GHz~12GHz, and the gain is as follows Figure 5 As shown, single-line polarization operation.
[0059] The radiation field strength of the horn antenna (Ant1) at 1.5m, 2m and 2.5m is simulated, and the difference in the gain-field strength relationship curve under theoretical calculation and simulation is compared.
[0060] from Figure 6 It can be seen that no matter the antenna power is 0.5W or 200W, when the correction coefficient C is 1.42, the gain-field strength relationship curve simulated by the horn antenna and the gain-field strength relationship curve calculated by the theoretical formula can be fitted together.
[0061] Similarly, under the premise that other conditions remain unchanged, the radiation field strength of the antenna at 2m and 2.5m is simulated to obtain the gain-field strength relationship curve, as shown in Figure 7 and Figure 8 As shown in Figure 2, it can be seen that the theoretical calculation curve and the simulation curve can still fit well.
[0062] The radiation field strength values of antenna Ant1 at 3m, 4m, and 8m were then simulated. The results showed that the simulation curve and the theoretical calculation curve can be well matched, that is, the field strength values radiated by the antenna meet the formula:
[0063]
[0064] Example 3
[0065] Based on the above inference formula (Equation (2), we can theoretically calculate and predict the radiation field strength values of existing antennas at different distances in the radiation link. We can also calculate the gain and power requirements that need to be met when designing the radiating antenna based on the required field strength value. For example, a radiating antenna with a specific gain can be used to accurately generate the required radiation field strength value at a low cost at a specific position in its radiation link. At the same time, the radiation field strength can be flexibly controlled by adjusting the relevant parameters of the antenna.
[0066] Based on Example 2, the first test scheme further includes: calculating the electric field strength at different locations along the radiation link under the condition that the radiation power and radiation gain of the high-gain radiating antenna are constant, and determining whether the electric field strength at the corresponding location meets preset requirements; if not, determining a safe radiation range. In actual applications, a large electric field environment may affect the human body or surrounding electronic devices. Therefore, based on the above inference formula, it is convenient to determine the radiation range of the target high-gain radiating antenna, and the device can be installed in a location away from people or other electronic devices as needed (i.e., within the safe radiation range).
[0067] Furthermore, in an embodiment of the present application, the second test scheme includes: with the goal of minimizing energy consumption, adjusting the radiation power and / or radiation gain of the high-gain radiating antenna so that the electric field strength at a predetermined position from the high-gain antenna reaches a preset value. As can be seen from the above-mentioned Example 1, increasing the radiation gain of the high-gain radiating antenna can save more testing costs than increasing the output power of the power amplifier. However, factors such as the upper limit of the radiation gain and the radiation range of the high-gain radiating antenna must also be considered. While the radiation range meets the requirements, the radiation gain of the high-gain radiating antenna should be increased as much as possible.
[0068] In summary, this application innovatively proposes a large field strength test system and method based on a high-gain antenna, which uses a high-gain radiating antenna to accurately and controllably radiate the required field strength value on the radiating link, and combines the receiving antenna and attenuator to achieve accurate measurement of the larger field strength value on the radiating link.
