3x3 Multibeam Network for a Triangular Array of Three Radiating Elements
A multibeam antenna study based on Butler network will be undertaken in this document. These antenna designs combines phase shift systems with multibeam networks to optimize multiple channel systems. The system will work at 1.7 GHz with circular polarization. Specifically, result simulations and measurements of 3 element triangular subarray will be shown. A 45 element triangular array will be formed by the subarrays. Using triangular subarrays, side lobes and crossing points are reduced
Synthesis of circularly polarized radial line slot array
In previous articles, an easy way to analyse a slot array fed through a radial line was presented. The analysis was based on a circuit approach where circuit parameters have been estimated using the first propagation mode in the radial line and the far field theory. Here we study the design of a particular application for circularly polarised broadside antenna. The design defines the length, position and orientation of the slots in the antenna surface. The final analysis of the antenna gives a good behaviour in field diagrams and gain
Análisis, diseño y realización de antenas planas ranuradas multisatélite
A review of designs of linearly polarized parallel-plate slot antennas developed by the authors is presented. Different combinations are described: broadside beam, one and dual tilted-beam, one and dual polarized antennas. The antenna structure, the
analysis methods and the feasibility of getting a dual beam and dual linearly polarized antenna with interesting characteristics and low cost are analyzed. Several designs are proposed and their features are studied. As a conclusion, it can be said that parallel-
plate slot arrays are quite promising
Diseño y construcción de antena plana de doble polarización basada en ranuras para recepción de TV por satélite
In this paper we design and make a double-polarization plane
slot antenna for Digital Television Satellite reception. The prototype will fulfil the DVB specifications and furthermore it should be simple to construct and cheap. Therefore in the design process and in the implementation process exists a compromise
between the specifications, low costs and simplicity

Diseño de antena monopulso de polarización circular en guía radial
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 antenna, with the slots placed on the upper plate in concentric rings. The radiation element is a slot pair, designed for getting left hand circular polarization. The antenna has been designed for working between 13.4 and 14 GHz. Both beams are obtained independently through very simple excitation circuits (Butler Networks). Comparing both radiation patterns, amplitude and phase, theta (0º to 10º) and phi (0º -360º) angles can be obtained
