A novel two-layer slot array antenna based on substrate integrated waveguide (SIW) technology was designed and simulated. Unlike already reported SIW slot arrays, the present design achieves considerable reduction in size by using a feed waveguide placed underneath the slot array and coupled through slanted slots to branches of the array. Radial Line Slot Antenna Design for Monopulse Space Debris Radar This paper presents the design process of a monopulse radial line slot antenna at 94 GHz for space debris detection. The paper has included the optimization process the calculation of the antenna gain through different efficiencies. Finally, a feeding network based on 4+1 pins is selected. The central pin generates the difference beam, while ... WIDEBAND PLANAR SLOT ANTENNAS - pdfs.semanticscholar.org
If the slot antenna is superimposed on its complementary dipole antenna structure, one would obtain an infinite conducting plane. Interestingly, employing certain symmetry in Maxwell's equations and realizing the complementary nature of the above two structures...
A novel approach for miniaturization of slot antennas ... A similar approach can be applied to design a meander type slot antenna [8]. In order to in- crease the efficiency of these antennas by reducing dissipation, the use of a high temperature superconductor (HTS) has been proposed [9], [10]. Design of U Slot Wideband Antenna Figure3. The S parameter of the U-slot patch antenna. Figure 4. The Radiation pattern of the U-slot patch antenna. 6. CONCLUSION AND FUTURE OUTLOOK This paper presents a new design procedure for the U-slot rectangular patch antenna based on previous literature and theoretical and parametric analyses.
Design of Slot Antenna for Wideband Applications
Design curves relating the elements of the equivalent circuit to the physical dimensions of the antenna are first established and then subsequently used to determine the parameters of the structure.
