FEED EFFECTS ON THE DIMENSIONS OF WIDEBAND SLOT ANTENNAS

摘要

The feed interaction of wideband slot antennas is analyzed using finite-element method optimizations. The achievable bandwidth with bow-tie feed is around 115% (more than 2:1) for VSWR ≤ 2 and a similar configuration could achieve a bandwidth of 45% for VSWR ≤ 2 with radial stub feed. The effect of feeding mechanisms on the dimensions of the slots is discussed. A comparison of measured results for various feed configurations is presented.
