“…Lower sidelobes than in the conventional counterparts have been achieved by means of the metamaterial surface. In order to simplify the antenna manufacturing a planar metasurface was presented in [24], where a metasurface implemented on a circuit board was used to create a soft horn antenna. Photographs of the prototype are shown in Fig.…”

“…This requires a brute force optimization which can be avoided if a tapered transition is implemented in the metamaterial wall liner. This approach has been followed in [25] Finally another implementation of this concept was used in [24], applied to a conical horn antenna. The metasurface was based on a mushroom structure, see…”

Millimetre-wave antenna systems have traditionally required high performance feeds in order to fulfil its stringent requirements. Therefore, this goal has been achieved by corrugated horns. However, in the last years new applications mainly in the communication area have driven the use of other types of antenna feed with slightly reduced performance but simpler manufacturing and reduced cost. The simplicity of manufacturing is especially critical as frequency increases and in fact corrugated horns are extremely difficult and expensive to manufacture at submm-wave frequencies.This chapter will cover the different alternatives currently used for mm-wave and submmwave antenna feeds: corrugated horns, smooth walled horns where multi-flare angle horns and splined horns will be introduced as alternatives to corrugated horns at mm-wave and submm-wave frequencies. Finally, the chapter will finish with the perspectives and actual research results regarding metamaterial based feeds towards future applications. Advanced corrugated horn antennasThis section describes the actual corrugated feed horn technologies employed at mm-wave frequencies. It begins explaining the principles of the electrical behaviour of the electrical fields inside a corrugated waveguide. The hybrid mode basis as a tool to help in the analysis of corrugated horns and the relation between waveguide modes and free space gaussian modes are explained to understand the behaviour of the different types of corrugated horn antennas.In fact, corrugated feed horns are difficult to manufacture as frequency increases and usually are not usually used above W band. The reason is that their manufacture results quite difficult being necessary to use for the manufacture expensive electroforming techniques or even stacked rings if the weight is not an important parameter. 4.2.

In this study, the design method and experimental presentation of low‐refractive‐index metasurfaces have been reported. These metasurfaces are employed in the interior E‐plane walls of a pyramidal horn antenna. The target is a linearly polarised horn antenna with low side lobe levels (SLLs) and symmetric radiation patterns in the Ku band (13–18 GHz) for satellite communications. Particle swarm optimisation algorithm has been applied to the design procedure to achieve low‐loss dispersion‐engineered metasurfaces with desirable surface impedance characteristics. The metasurfaces were fabricated using precise low‐cost printed‐circuit board technique. There was perfect agreement between the measurement and simulation results. The fabricated horn showed low SLLs and an increase in the gain across the entire bandwidth. The SLLs are reduced by 14–29 dB in the E‐planes and the gain is improved by 1.2–2.3 dB compared with a corresponding conventional horn. The far field radiation patterns of the metahorn verify the metasurface design approach. Furthermore, this method assures a lighter horn with an easier manufacturing technique in comparison with the other conventional horns, such as corrugated horns.

“…In [13], a MTS designed using a genetic algorithm has been used as an inner surface for a conical horn and the cross-polar levels and the side lobe levels have been improved over the entire Ku band. A similar approach was applied to improve the performance of a hybrid mode square horn antenna [14].…”

A complementary frequency selective surface (CFSS) can be formed on the basis of Babinet's principle. It consists of an array of slots separated from an array of dipoles by a thin dielectric substrate. This study shows that by adding an extra layer of dipoles to a CFSS capacitance can be added to the structure, which leads to a decrease in its resonant frequency. This new structure is called a dipole-slot-dipole metasurface (MTS) and it has unit-cell dimensions of l/10 × l/10 × l/333, where l is representing the free space wavelength. The dipole-slot-dipole MTS has been fabricated and measured. The study also reports on its equivalent circuit; and the effects of the length of the dipoles on the added layer and their alignment on the pass band resonant frequency of the dipole-slot-dipole MTS.
