Abstract
A novel dual-band miniaturized patch antenna with negative-refractive-index transmission lines (NRI-TLs) for UAV (Unmanned Aerial Vehicle) applications is proposed in this paper. The proposed antenna comprises two parts. One is a U-shaped cavity-backed antenna composed of a planar double-sector patch with two symmetrical meandering lines and a U-shaped backed-cavity. The other one is negative-refractive-index transmission lines, which are used to achieve size reduction for the U-shaped cavity-backed antenna. Although the U-shaped cavity-backed antenna and the proposed antenna have the same size of $36\text{cm}\times 40\text{cm}\times 25\text{cm}$, the proposed antenna can operate in a lower frequency band. Due to the introduction of the negative-refractive-index transmission lines, the overall size reduction is up to 12.3%. This miniaturized patch antenna with NRI-TLs is well suited to the design of UAV system.
