Single Feed Multi-Resonant Connected Metasurface Antenna for Nano-Satellite Applications

This paper presents a single-fed multi-resonant metasurface antenna structure. The structure has two layers, a patch antenna feed layer, and a metasurface layer. The proposed antenna structure is very adaptable to different substrate configurations and it supports low profile antennas designs. The proposed antenna structure will be presented through three design examples. The first design example is a dual-band configuration for 17GHz and 20GHz. The antenna is simulated to have a gain of more than 6dBi at both of these frequencies. The second design example shows how the feed patch and the metasurface layer of the dual-band configuration can be easily modified to achieve right hand circular polarization for the two bands without any performance loss. The last design example shows how the dual-band configuration can be extended to a triple-band configuration. An additional resonance at 12.5GHz is achieved by adding an additional metasurface ring on the top layer.
