When designing an antenna system for radiating a transient pulse, it is necessary to have a simple model for each of the competing antennas, in order to make comparisons. Previous work on TEM horns has provided numerical models, however no simple model exists. The purpose of this paper is to provide such a simple model. The model consists of approximating the TEM horn by a continuum of electric...

Abstract This letter proposes a class of sine corrugated cavity resonators (SCCR). The SCCR can present slow‐wave features and provide dual‐mode (TE 104 TE 105 ) wideband responses with reasonable period depth. Based on it, compact high‐gain bandwidth‐enhanced slot antenna array is designed. high gain obtained seven radiation slots the achieved due to three modes being utilised. include one fee...
