“…The leaky modes excited in open microstrip-like structures have been studied in the past by many researchers [1][2][3][4][5][6][7][8][9][10][11][12][13]. This radiation mechanism can be undesirable for printed-circuit applications, since it can cause interference and thus deteriorate the system performance.…”

“…This radiation mechanism can be undesirable for printed-circuit applications, since it can cause interference and thus deteriorate the system performance. On the contrary, this radiation mechanism can be used in the design of leaky wave antennas [5,[11][12][13]. In any case, it is always convenient to control this leakage effect.…”

“…In addition, in [11][12][13] the field pattern is computed, but the leaky wave antenna is built using an empty waveguide with no dielectrics or printed metal strips. In the structure we propose, a suspended dielectric substrate is used in order to obtain a high gain behavior following similar ideas as those presented in [5].…”

“…In addition to these iterative strategies, graphical procedures to approximately locate the complex leaky wave poles have also been derived [9]. Also, although many investigations have been conducted for basic printed lines [1][2][3][4][5][6][7][8][9][10], the same is not generally true for laterally shielded configurations. In all previous works, the infinite nature of the dielectric substrates yields to continuous wavenumbers in the spectral domain.…”

In this paper the leakage effects in open laterally‐shielded multilayered microstrip transmission lines are investigated. Potential solutions are often reported to be difficult to find, since they are located in the complex propagating factor plane. To overcome this problem, a novel iterative algorithm is implemented to relate the solutions in the real axis of closed transmission lines with their corresponding complex open structure modes. The problem of modeling the leaky behavior of the open top wall is introduced, and a mathematical and physical explanation of the solutions is proposed. The advantage of this new technique is that it allows us to easily track the leaky solutions to their final location in the complex plane. Results are presented, including the field and power patterns associated to leaky waves, showing that the derived technique is indeed effective for the study of the complex modes excited in this type of structures. © 2003 Wiley Periodicals, Inc.

“…In this case an arrangement of dielectric substrates or impedance surfaces is placed over a metallic ground plane in order to enhance and/or modify the radiation properties of simple elementary sources. In particular, the possibility to enhance the gain of simple sources in the broadside direction has been widely investigated in literature [2]- [10]. Pattern shaping using leaky-wave modes and Fabry-Perot antennas have been also proposed in [11]- [13] for maximizing the aperture efficiency and edge of coverage gain of reflector systems.…”

Abstract-This paper describes the design of a planar FabryPerot leaky wave antenna generating a flat-topped radiation pattern. The flat-topped pattern is achieved by exciting various leaky-wave modes between a metallic ground plane and a superstrate. Two configurations for the superstrate structure are proposed and analyzed: i) dielectric layers; ii) impedance sheets. In all cases, the antennas are fed by a small waveguide opening in the ground plane. An in-house optimization tool based on a Green's function spectral approach is used to derive the appropriate arrangement for the generation of the required flattopped pattern. The proposed approach is validated numerically for an antenna generating a flat topped pattern with a beamwidth of ±25 • . The proposed flat-topped antenna may be used for the design of phased arrays with reduced scan losses over a given angular range.Index Terms-leaky-wave antennas, phased array antennas, flat-topped element pattern.
