Pattern recovering of conformai phased array on changing surfaces is receiving an increasing attention in the last years. This paper presents the pattern recovery of a strongly deformed conformal phased-array using the projection method. A 4 × 4 flat array is placed on a doubly curved surface. The phase compensation technique is applied first on rows, and then, considering rows as single antenna elements,...
Conformal antennas placed on complex surfaces are receiving more attention as a method to increase the coverage of modern wireless communication systems. Furthermore, frequency reconfigurable antennas are being used in the development of multi-band multi-radio wireless platforms to simplify designs. In this study, theoretical development and a new 1 × 4 frequency reconfigurable self-adapting conformal...
In this paper, an initial study on the possible use of carbon microfibers as a transmission line (TL) feed network in conformal microstrip antenna arrays was conducted. Initially, a 12.0 cm long 50 Ω microfiber transmission line was manufactured and the wave propagation properties were measured. These characteristics were then compared to the propagation properties of a traditional copper microstrip...
The use of graphene-based conductors (GBC) as a transmission line (TL) is presented as a conventional TL possessing right-handed (RH) nature and its coupling characteristics are investigated. In order to verify and demonstrate the wave propagation of a GBC TL, a 120 mm long 50 Ω TL was fabricated and tested. Performance of the single GBC TL was then compared to the conventional microstrip TL, analyzing...
In this paper, a compact planar Ultra-Wideband (UWB) Multiple-input Multiple-output (MIMO) antenna array is proposed. This UWB-MIMO antenna array consists of two identical monopole antenna elements with a novel decoupling structure etched on the ground plane. The antenna performs very well over the UWB frequency range of 3.1–10.6 GHz. The decoupling structure improves the isolation between the antennas...
