A traditional radial line slot antenna (RLSA) is a high gain planar array. To improve the power handling capacity, we design a radial line slow wave structure whichThis high power microwave (HPM) RLSA is fed from a double-layered radial line waveguide to realize the directional radiation of the microwave. Small Antennas for High Frequencies | Radiation Patterns Electric Field of Linear, Circular, and Elliptical Antenna Polarizations. In the real world there is no perfect Linear or perfect Circular polarized antennas.antenna with no extra fabrication steps (e.g., branch line hybrid to produce circular polarization or corporate feed network for an array of microstrip... Antenna | Pr = z The Average radiation intensity is Antenna. z Antennas form a very important element in communication system, either terrestrial or extra terrestrial, depending on the mission type and requirements. z "That part of a transmitting or receiving system which is designed to radiate or to receive electromagnetic waves".

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.
Beam shaping is a challenging assignment for radial line slot antennas (RLSAs) which operate on oversized parallel plate waveguides. A RLSA for an elliptical beam with an elliptical aperture is designed and measured at 22GHz. Radiuses of the major and minor axes are 300mm and 150mm for an ellipticity of 2:1.
