“…In these antennas the basic reflector have a parabolic and elliptic forms that illuminated by compound feeds are used. Use of metamaterials as a part of the feed HRA of a range of 30 GHz is discussed in (Chantalat et al, 2008). The wide range of beam scanning is provided by parabolic cylindrical reflectors (Janpugdee et al, 2008), but only in once plane of the cylinder.…”

The dual‐grid (DG) technique is implemented in the body‐of‐revolution FDTD algorithm (BoR‐FDTD) for the fast analysis of large rotationally symmetric antennas.The proposed technique combines two BoR‐FDTD simulations performed successively with fine and coarse mesh schemes, respectively. First, all excitation sources are analyzed locally with a fine mesh resolution and the near‐field distributions are saved. Second, the whole problem (feeds and scatterers) is modeled using a coarser mesh where the computational domain is excited by the equivalent sources stored at the first stage. The continuity between these two simulations is guarantied by means of linear field interpolation or sampling (in space and time) and total/scattered field formulation. The relevance of the proposed technique is demonstrated through the analysis of a 60 × λ0 parabolic antenna system illuminated by an electromagnetic band gap feed. The DG technique is found to be accurate and faster than the classical BoR‐FDTD approach. Our results also show that significant savings are obtained in terms of computation time and memory. The DG‐BoR‐FDTD strategy is considered as a powerful and flexible approach to analyze the influence of the surrounding environments without having to repeat the expensive part of the simulation. © 2012 Wiley Periodicals, Inc.

“…This quarter-wavelength gap results in two problems, that is, narrow bandwidth and bulky size. To alleviate these problems, electromagnetic bandgap (EBG) structure, which is also known as metamaterial, photonic bandgap (PBG), or hard/soft surfaces, is proposed by changing the surface characteristics on the ground [7][8][9][10].…”

This paper proposes minimized low-profile wideband antenna by employing high impedance surface (HIS), for wireless application scenarios at radio frequency, microwave, and even terahertz. To validate this concept with low cost and easy measurement, two prototypes at radio frequency are fabricated and tested. Firstly, antenna with dielectric-substrate reflector is proposed and analyzed and 4 × 6 HIS array is employed to minimize the antenna size to 0.57 × 0.86 × 0.078 , while maintaining antenna performances such as bandwidth, gain, and directive radiation. Secondly, a substrate-less HIS is proposed to improve the antenna bandwidth from 36% to 52% and also reduces the antenna weight by 72%.
