Summary:
In recent years, various researches onto microstrip patch antennas have been actively conducted because of a low profile, a light weight, a small volume and an easy fabrication [1]. As a microstrip patch antenna yields a narrow bandwidth [2], a stacked multi-resonator structure [3] and a coupled feed method [4] have been proposed to improve its bandwidth. However these schemes are complicated in a structure due to a multilayer configuration. In this paper, a new planar magnetic monopole antenna is proposed to improve the bandwidth and reduce size of the antenna via an electromagnetic band-gap (EBG) structure [5], [6]. The proposed antenna consists of isotropically periodic hexagonal patches with equilateral slots on the top side and equilateral triangular slots on the ground plane. This magnetic monopole antenna yields a different radiation pattern compared to a conventional patch antenna and a large bandwidth with a size reduction. The design and analysis of the proposed antenna is described in section 2 and experimental results are discussed in section 3.
