“…Such devices imply high cost and bulky structures and, even if the design of corporate and series-fed networks are well established, they typically require the use of large, often lossy and expensive implementations (see, e.g., [3]). Alternatives techniques have also been proposed in the last decade, such as tunable inductive partially reflective surfaces (PRSs) [4], phase modulated metasurfaces [5], phase transformers [6], [7], slotted structures [8], lenses [9], [10], composite feeding networks [11], and active frequency selective surfaces [12].…”

“…Thanks to the leaky-wave mode supported by the structure, the proposed antenna also provides steering in elevation of a directional pencil beam, in contrast with the steering strategies described in [11], [12], where, to achieve azimuth beam steering, a reconfigurable cascaded feeding network connected to endfire radiating elements and an active frequency selective surface were employed.…”

We propose the design and test of a 2-D Fabry-Perot structure based on a multilayer slab arrangement fed by a circular array of simple sources. Such a class of planar leakywave antenna can be made by low-loss commercial laminates and it is bounded on top by a sub-wavelength partially-reflecting surface. The antenna is designed to suppress undesired radiation from the quasi-TEM mode while leaking power by the excitation of a fast TM1 leaky mode, which is a perturbed version of the guided-wave supported by the corresponding parallel-plate waveguide. An accurate dispersive analysis for the multilayer structure is developed and an original feeding system is designed and optimized to provide the needed wideband impedance matching. Thanks to translational invariance enabled by the homogenized nature of the partially reflecting screen, the antenna is used as a radiating element in the design of a leaky-waveenhanced phased array, constituted by an arrangement of vertical probes to generate directive pencil beams steerable at a single frequency in azimuth and by changing frequency in elevation.

“…A brief survey of recent antenna array design techniques to realize multi-beam is discussed next. The paper in [4] introduces a way to beam-switch along the azimuthal plane along 360°without the use of conventional butler matrices, phase feeding networks or ESPAR-based strategies. It uses quasi-lumped couplers (QLCs) which are a pair of parallel transmission lines separated by two tunable varactors giving rise to a four-port network.…”

“…A comparison of the proposed antenna array and its operation to the above-related works is presented next. In comparison to the paper in [4], the proposed beam-switching scheme operates in the radiating half-plane rather than in the azimuth 360°plane. It also operates at a frequency of 14 GHz as compared to 1 GHz in the QLC design and does not employ multi-layered rat-race couplers for multimode beam-switching operation.…”

The paper presents a two-phase state based multi-beam-switching scheme implemented on a customdesigned 4 × 4 antenna array operating with a bandwidth of 1.5 GHz around 14 GHz. The antenna array and the beam-switching scheme have been experimentally validated. A phasing network designed to produce two phase states is used to experimentally validate the beam-switching and five beam states are presented, though this can be extended to other configurations using the split beam as a building block to construct multiple beams. The antenna can find potential use in multiuser millimetre-wave massive MIMO scenarios which require simultaneous multiple beams along selective directions.

This thesis investigates various methods to improve the performances of antennas. For different applications, the antennas are expected to have corresponding performances and characteristics. The efficiency is one of the most important parameters that should be considered, and the losses determine the efficiency directly. For different types of antennas operating in different frequency bands, there exist different factors which influence the performances. For example, in the HF band (3 MHz-30 MHz), the performances depend on the mismatch loss and the size of the antenna. In the microwave frequency band, besides the mismatch loss, the dielectric loss of the substrate material is also one of the most important factors. Whereas in the millimeter wave frequency band, the loss in the feeding network is the factor that limite antenna gain and efficiency when the sub-antennas are all matched well. Considering various influence factors, different techniques and methods are investigated to improve the performances. First, the compact and effective ferrites are selected to improve the performances of the HF antennas. Effective methods of using ferrites are proposed to improve the performances of the HF antenna. By analyzing the current in the ground plane of the antenna, the
