Abstract

The invention relates to an implantable antenna work site performance test method and system. The method comprises the following steps: acquiring a field test signal of a tested implantable antenna byusing a free space test field, acquiring an antenna direct wave signal in the field test signal by using a time domain gate function, and according to the antenna direct wave signal and an antenna model of the implantable antenna based on an electromagnetic field time domain integral equation theory and a time recursion method, obtaining the radiation characteristic of the implantable antenna; and based on a time domain EPMCHW algorithm, obtaining the far-field radiation characteristics of the implantable antenna in the work site model according to the radiation characteristics of the implantable antenna. According to the method, the influence of the equipment where the implantable antenna is located and the application environment of the implantable antenna on the antenna radiation performance is considered, the far-field radiation characteristics of the implantable antenna in the specific application environment are obtained on the basis, targeted performance testing can be carriedout on the implantable antenna in the working site environment, and a more accurate testing result is obtained.

Description

technical field [0001] The present application relates to the technical field of antenna testing, in particular to a method and system for testing the performance of an implanted antenna at a working site. Background technique [0002] With the improvement of equipment integration and integration requirements, more and more equipment in electronic information systems such as vehicles, aircraft, ships, and satellites begin to use implanted antennas. Unlike stand-alone antennas that stick out of the device, implanted antennas are shaped for a specific device and are often embedded or wrapped to closely fit the device. Therefore, when testing the implanted antenna, it is necessary to start from the perspective of the whole device, and it is necessary to consider the influence of the application environment of the device on the performance of the implanted antenna. [0003] Due to the close relationship between the implanted antenna and the corresponding equipment and applicati...
