Abstract

The theory of characteristic modes (TCM) is gaining momentum in the analysis of slot antennas, whose size is comperable to the metallic plane or chassis. In this paper, we will analyze the behavior of a circular slot on a fixed ground plane (GND). Circular slots having small dimensions compared to the GND do not alter the characteristic mode (CM) current distribution and the Modal Significance (MS) plots significantly but when the size of such slots increases, new slot modes are created. Some of the chassis modes are modified due to the presence of a slot at their current maxima. The generation of the slot mode depends on the size and the location of circular slot on the chassis.
