通过不小于500次的微带电路结构设计，以及通过不低于500次仿真试验和参数调整下，最终确定了上述天线结构，而实际测试中，上天线和下天线均能单独实现天线通信功能，这样以来，如果有一个天线因为浸水或者其他原因而发生故障，另外一个天线也能继续发挥作用，使得植入式的检测器具备较强的适应能力和使用寿命，也提高了稳定性。Through no less than 500 times of microstrip circuit structure design, and no less than 500 times of simulation tests and parameter adjustments, the above antenna structure is finally determined. In actual tests, both the upper antenna and the lower antenna can independently realize the antenna communication function. In this way, if one antenna fails due to water immersion or other reasons, the other antenna can continue to function, so that the implantable detector has strong adaptability and service life, and also improves stability.
上天线的单独测试：通过仿真测试和实际测试发现，其频率范围在2.0GHz至2.75GHz左右，频带内平均增益为8.5dBi左右，方向性为全向性，其基本能满足通信要求。另外，下天线的单独测试：通过仿真测试和实际测试发现，其频率范围在1.9GHz至2.8GHz左右，频带内平均增益为9.0dBi左右，方向性为全向性，其也基本能满足通信要求。Separate test of the upper antenna: Through simulation test and actual test, it is found that its frequency range is about 2.0GHz to 2.75GHz, the average gain in the frequency band is about 8.5dBi, and the directivity is omnidirectional, which can basically meet the communication requirements. In addition, the separate test of the lower antenna: through the simulation test and the actual test, it is found that its frequency range is about 1.9GHz to 2.8GHz, the average gain in the frequency band is about 9.0dBi, and the directivity is omnidirectional, which can basically meet the communication requirements. .
值得说明的是，经过不断的测试和天线构造的调整，当上天线和下天线配合时，在实际测试与测试之前的仿真中可以得知，配合在一起的通信天线组成的通信天线系统的带宽、隔离度、增益方面均具有较大的提升，这其中，值得注意的是增益和带宽频率范围并不是两者数据的简单叠加，而是具备了新的效果，其中配合后的仿真值如图5；该整体天线系统带宽可用频率范围达到了1.7GHz至2.9GHz；其增益也明显增加，频带内平均增益大于9.355dBi，相比上升0.7dBi左右；另外，如果加上隔离板2，其隔离度如果图频带内隔离度，隔离度表现会较好，如图5，在S3中可以看出在频率范围内隔离度大于25.5dB；其方向性也好，如图6所述，其依然为全向性天线。It is worth noting that after continuous testing and adjustment of the antenna structure, when the upper antenna and the lower antenna cooperate, it can be known from the actual test and the simulation before the test that the bandwidth of the communication antenna system composed of the communication antennas that are matched together , isolation, and gain have all been greatly improved. Among them, it is worth noting that the gain and bandwidth frequency range are not a simple superposition of the two data, but have new effects. The simulated values after matching are shown in the figure 5. The available frequency range of the overall antenna system bandwidth has reached 1.7GHz to 2.9GHz; its gain has also increased significantly, and the average gain in the frequency band is greater than 9.355dBi, which is about 0.7dBi higher than that; in addition, if the isolation board 2 is added, its isolation If the isolation within the frequency band is shown in Figure 5, the isolation performance will be better, as shown in Figure 5. It can be seen from S3 that the isolation within the frequency range is greater than 25.5dB; its directivity is also good, as shown in Figure 6, it is still omnidirectional antenna.
