Two types of RLSAs, a single-layered and a double-layered one, were released commercially for 12 GHz band direct broadcast satellite (DBS) reception. Radial line slot array (RLSA) antenna design for point to ... A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz.
A radial line slot antenna (RLSA) is a slotted waveguide planar array proposed for DBS subscriber antennas. The predicted conductor loss of the RLSAIt utilizes a radially outward-traveling wave and the aperture field is intolerably tapered if the uniform slots are used. Two novel techniques are applied.

The linearly polarized radial line slots array antenna exhibits poor return loss. This problem was tackled by imploring the beam squinting and reflection cancelling slots techniques. This paper suggests the use of a numerical solution for selection RADIAL WAVEGUIDE SLOT ARRAY ANTENNA DESIGN AND IMPLEMENTATION ... and antenna design modeling in the software environment have been presented, simulation analysis was performed and the optimum results were obtained for 2.4GHz RWSA antenna. Radial Waveguide Slot array antenna was successfully fabricated. Then, return loss Radiation pattern and received signal strength were measured and performed. Design Method, Analysis and Prototypes of Radial Line Slot ... II. Radial Line Slot Antenna Structure Figure 1 shows the structure of the antenna. A Radial Line Slot Antenna is formed by a parallel plate structure, whose height is less than half a wavelength to avoid the propagation of upper modes. A radial TEM mode is generated through a coaxial probe (or several probes). Resonant-tunneling-diode terahertz oscillator integrated with ... Among them, we employed the radial line slot antenna (RLSA) [21, 22] by changing the antenna size for THz waves and proposing a structure coupling to the RTD. In the integration of the RLSA and RTD, the oscillator structure can be simply composed of a substrate and two electrodes on and under it, except for the resonator and RTD.
