The authors propose the design of one radial line slot antenna with two simultaneous
beams, one broadside beam and one conical beam. The antenna is a radial line slot …

Coupling between slots and slow-wave waveguides in a radial line slot antenna (RLSA) is
discussed. Field analysis of the waveguide with a surface impedance wall revealed a …

Subscriber antennas for receiving direct broadcast froma satellite (DBS) should possess
high gain characteristics of about 36 to 37 dBi in 12GHz band. A Radial Line Slot Antenna is …

A radial line slot antenna radiating a circularly polarised conical beam is proposed. It is
advantageous in the construction of a feeding structure comparing with conventional …

An analysis model is proposed to evaluate the slot coupling in a radial line slot antenna. The
effects of the waveguide thickness, the permittivity of the dielectric, and the slot length on slot …

This paper discusses how to design a Radial Line Slot Antenna (RLSA) whose waveguide is
filled with high loss dielectric materials. We introduce a new design for the aperture slot …

Radial line slot antennas (RLSAs) are designed for high gain millimetre wave systems. Two
types of RLSA are tested in the 60 GHz band: one is the conventional structure consisting of …

The Radial Line Slot Array (RLSA) antenna is known for its good characteristics such as low
profile, low cost, aesthetically pleasing, ease of installation and simple structure. This …

Extremely small aperture radial line slot antennas (RLSAs) are analyzed by method of
moments. At first, the analysis model of cylindrical waveguide in terms of rectangular cavity …

A novel design of a broad-band radial slot antenna fed by a coplanar waveguide for dual-
frequency operation is presented. Various frequency ratios, within the range of about 1.3 to …
