Analysis of an Ultra- Wideband Ridged Horn Antenna Based on Traveling Wave Current Model

Analysis and Experiment of a Ridged Horn Antenna With Metallic Grid Sidewalls

“…The equivalent traveling wave current model of ridged horn antenna is proposed in the previous paper [22] presented by the authors' team. The reason of directional radiation of ridged horn antenna in broadband is explained preliminarily.…”

“…The model is simple and easy to understand. However, only the E-plane and H-plane expressions of the equivalent traveling wave current model are calculated in [22], Modified traveling wave current model in this paper (model-2). and the 3-D expressions of patterns are not given.…”

“…Moreover, the matching effect between patterns calculated by equivalent traveling wave current model in [22] and patterns simulated in CST becomes worse in the high frequency band. Therefore, in view of the problems of the model in paper [22] and considering the difference between the exponential ridge curve and the straight line, a modified equivalent traveling wave current model is proposed. And the 3-D expressions of radiation patterns are calculated by using the mathematical method of geometry based on the modified model.…”

“…As shown in Figure 9, model-1 is the equivalent traveling wave current model proposed in the previous paper [22], and model-2 is the modified equivalent traveling wave current model proposed in this paper. The angle relationship in the graph is α 1 < α 2 < α 3 , α = α 2 .…”

“…Firstly, the TEM ridged horn antenna is designed. A modified equivalent traveling wave current model is proposed on basis of the previous paper [22] presented by the authors' team. The modified traveling wave current model reduces the error between the straight line and the exponential ridge curve.…”
