The paper describes a deterministic algorithm based on simple analytical equations for
designing planar circular sparse array antennas where the positions and the dimensions of …

The synthesis of electrically large, aperiodic planar arrays with equi-amplitude excitations
plays an increasingly relevant role in satellite applications. Unfortunately, for such a kind of …

Non-periodic, sparse Direct Radiating Arrays employing equi-amplitude (isophoric) radiators
represent an appealing solution to meet the requirements of next satellite services. In this …

A novel fractal antenna-array type is proposed. The design is based on the Sierpinski
rectangular carpet concept. However, the generator is a circular ring area, filled with …

The paper describes a deterministic algorithm based on simple analytical expressions for
designing linear sparse array antennas, composed of not overlapping linear sub-apertures …

New deterministic procedures for the design of linear aperiodic arrays are described, which
permit exploiting, in a combined way, both the positions and the excitation amplitudes of the …

In this paper, we address the synthesis of isophoric sparse ring arrays for full Earth coverage
from a GEO satellite by means of steerable beams, switchable between two different widths …

In active array antennas for satellite communications, one wants to reduce as much as
possible the number of control points while fulfilling severe constraints on gain for each of …

A simple deterministic synthesis method for the design of aperiodic planar arrays with
elements arranged on circular or elliptical rings is presented. Differing from other techniques …

This article proposes a systematic approach for stacking uniform linear arrays (ULAs) of
different sizes to reduce sidelobes and form nulls to the radiated beam pattern. In sidelobe …
