Abstract
A microstrip-fed ultra-wideband slot antenna Abstract: Ultra-wideband (UWB) antennas have gained great interest since the US Federal Communication Commssion (FCC) released the generic admission for UWB in the frequency band between 3.1 GHz-10.6 GHz in 2002. Figure 1: a) Illustration of a broadband absorbing slot antenna metasurface consisting of six dierently tuned slot antennas tiled with subwavelength periodicity. The graphene patches are color- coded by antenna length, and the diagram is drawn to proportion based on the device dimensions used to produce Figure 5. A numerical simulation and an experimental implementation of T‐shaped microstrip‐fed printed slot array antenna are presented in this paper. The proposed antenna with relative permittivity 4.3 and thickness 1.0mm is analyzed by the finite‐difference time‐domain (FDTD) method.
The metasurface concept has emerged as an advantageous reconfigurable antenna architecture for beam forming and wave-front shaping, with applications that include satellite and terrestrial communications, radar, imaging, and wireless power transfer. The metasurface antenna consists of an array of metamaterial elements distributed over an electrically large structure, each subwavelength in dimension and with subwavelength separation between elements. In the antenna configuration we consider, the metasurface is excited by the fields from an attached waveguide. Each metamaterial element can be modeled as a polarizable dipole that couples the waveguide mode to radiation modes. Distinct from the phased array and electronically-scanned-antenna architectures, a dynamic metasurface antenna does not require active phase shifters and amplifiers but rather achieves reconfigurability by shifting the resonance frequency of each individual metamaterial element. We derive the basic properties of a one-dimensional waveguide-fed metasurface antenna in the approximation in which the metamaterial elements do not perturb the waveguide mode and are noninteracting. We derive analytical approximations for the array factors of the one-dimensional antenna, including the effective polarizabilities needed for amplitude-only, phase-only, and binary constraints. Using full-wave numerical simulations, we confirm the analysis, modeling waveguides with slots or complementary metamaterial elements patterned into one of the surfaces.
