Design and Implementation of RSLA Antenna for Mobile DBS ... Conclusions • A SOTM (satellite on the move) DBS receiver has been designed and implemented successfully based on Radial Line Slot Array (RLSA) antenna which operates at Ku band. • This RLSA antenna has eight concentric array slot pairs to achieve conical beam, better gain and wider frequency bandwith compared to Makoto Ando model. Sidewall Waveguide Slot Antenna for High Power Sidewall Waveguide Slot Antenna for High Power Carl E. Baum University of New Mexico Department of Electrical and Computer Engineering Albuquerque New Mexico 87131 Abstract This paper discusses a concept for high-power microwave antennas based on an array of slots in the sidewall where the electric fields are lower.

Antenna gain, however, is a directional quantity that refers to the signal that can be derived from an antenna relative to a reference dipole. 2.9.1. The Model Fig.2.17 illustrates an antenna loss model in which a resistor is placed in … Dipole antenna - Wikipedia For instance, a full-wave dipole antenna can be made with two half-wavelength conductors placed end to end for a total length of approximately L = λ. This results in an additional gain over a half-wave dipole of about 2 dB, but the huge …

3. Results for Radial Line Slot Antennas The source reconstruction technique has been applied to the simulated and the measured data of a K-band radial line slot antenna (RLSA) shown in Fig. 3 and the designed magnetic current at each slot. The RLSA consists of 1062 slots, and operates at 19.9 GHz.

The substrate of elliptical design, the slots, and the connection between slots, the antenna consists of dielectric FR4 with an epsilon of 4.9. the cylindrical patches and the dimensions of the ground Dimension wise, it is (38.1×22) mm with thickness of 1.6mm. plane, substrate, parasitic ring and the substrates used as a support for the ring element.

US9214740B2 - Radial line slot array antenna - Google Patents A radial line slot array antenna in general has a plurality of slots arranged to fit a specific frequency (central frequency of used frequency band), and hence has a problem that the usable frequency band is narrow. The radial line slot array antenna described in Patent Literature 2 is intended to solve the aforementioned problem. IET Digital Library: Radial line slot array antenna with ... The authors present concentrically arrayed radial line slot array antenna for operation at 106 GHz. For compact design, they propose a vertical waveguide feeding with a cross-slot structure at the waveguide to cavity transition. Aperture design and optimisation are carried out using particle swarm optimisation with the goal to minimise the cross-polarised radiation. Multilayered Cavity Material Radial Line Slot Array ... Khan, 2011)) are being considered. At millimeter wave band, microstrip antenna design becomes challenging and to date little is known about antenna design at millimeter wave for cellular or mobile communication (Chen & Zhang, 2013). Radial Line Slot Array (RLSA) antenna with its starling characteristic of high gain, low cost,
