Abstract

The invention discloses a Koch snowflake ultra-wideband reverse modeling method based on an IACO-BRBP neural network, and the method mainly comprises the steps: 1, obtaining experimental data, and dividing the experimental data into a training set and a test set; 2, improving a traditional ant colony algorithm; 3, training the BRBP forward model by using the improved ant colony algorithm, and storing the optimized weight; 4, keeping the weight unchanged, and inputting an electric parameter in the established IACO-BRBP model to realize a reverse solving process; 5, calculating an evaluation function between the output parameter and the target parameter; 6, updating the input parameters by using a reverse iteration algorithm. According to the method, the IACO-BRBP neural network reverse modeling method is applied to the improved Koch snowflake-type ultra-wideband antenna, so that corresponding structural parameters can be solved according to given antenna electrical parameters; once the training of the reverse model is completed, the geometric parameters of the antenna can be quickly simulated only by inputting target electrical parameters; therefore, the design period is greatly shortened while the design requirement is basically met.

Description

technical field

[0001] The invention belongs to a neural network reverse modeling research method of a radio frequency microwave device, in particular to a Koch snowflake-type ultra-wideband antenna reverse modeling method based on an IACO-BRBP neural network. Background technique

[0002] In recent years, with the rapid development of wireless communication technology, the antenna plays an indispensable role. It is the core component for transmitting and receiving wireless electromagnetic waves and completing electromagnetic conversion. Among them, the UWB communication system occupies a wide range of frequency bands, covering many narrowband communication standards, such as IEEE 802.16 Worldwide Microwave Access (WIMAX, 3.3-3.7GHz), IEEE 802.11a Wireless Local Area Network (WLAN, 5.15-5.35GHz / 5.725-5.825GHz), etc. The transmission power of the UWB system is relatively low, and it is easy to form crosstalk with these narrowband communication systems. Therefore, an UWB ant...
