Abstract

This paper presents the development of a novel low profile dual-band co-planar waveguide (CPW)-fed split ring-shaped antenna with improved radiation performance in the broadside direction using a frequency selective surface (FSS)-based artificial magnetic conductor (AMC). The CPW-fed split ring antenna is developed to operate at the two operating bands with the center frequencies of 2.4 GHz and 5.8 GHz, having bi-directional radiation characteristics. The FSS-based AMC is designed with the reflection phase close to 0° for the corresponding resonating frequencies of both the working bands of the antenna. The proposed AMC is introduced as a substrate at a relatively lower spacing of λ/12, which is much less than the quarter-wavelength spacing as used in the conventional approach for enhancing antenna gain at the broadside direction. By embedding the FSS-based AMC layer, the antenna exhibits the highest gain of 8.5 dBi and 8.92 dBi in the lower and upper bands, respectively.
