In this paper, a novel metamaterial absorber working in the C band frequency range has been proposed to reduce the in-band Radar Cross Section (RCS) of a typical planar antenna. The absorber is first designed in the shape of a hexagonal ring structure having dipoles at the corresponding arms of the rings. The various geometrical parameters of the proposed metamaterial structure have first been optimized...
This paper presents a microstrip rectangular loop antenna for wearable application. The substrate used for the prototype model is a FR4 material. The designed antenna can be integrated with a watch and is suitable for the wearable application. The characteristics of the prototype antenna developed, are measured in terms of the return loss, VSWR bandwidth, and radiation pattern. It is found that the...
