Abstract


This article is based on the basic model of the TEM horn antenna , designed a new type of ribbon horn antenna . The design taking into account the considerations of the antenna radiation efficiency and lightweight , with two curved narrow-band instead of the basic model of the upper plate so that the ribbon horn antenna can operate in a lower frequency range . Firstly, some of the important physical size of the horn antenna , the use of ANSOFT HFSS simulation software was analyzed to obtain the relationship between the various parameters of the antenna performance of the streamer horn antenna . The simulation results show that the model is effective to improve the low frequency performance of the TEM horn antenna , the broadening of the band of the antenna . Compared to other TEM horn antenna , this design reduces the balun structure . Second, the model on the basis of the ribbon horn antenna , after the initial model adjusted to optimize the design of the form of the narrow-band structure , making it more flexible gradient , and using the up and down gradual process . Simulation results show that : the improved ribbon horn antenna model compared with the initial model , more effectively improve the performance of the antenna radiation in the low-frequency band , reducing the reflection of energy , further broadening the operating frequency range . The improved the streamers horn antenna in the frequency range of 0.1GHz to 4GHz , VSWR is maintained below 2.0 , as compared with the initial model , significantly reduce the VSWR of the antenna , to increase the usefulness of the antenna . Finally, the initial model of the streamer horn antenna arraying order to increase the antenna gain and improve the radiation pattern of the antenna .
