Analysis of Unequally Spaced Linear Antenna Arrays to Realize Aperture Tapering

It is essential to simplify the feed network in tapered antenna arrays to reduce its cost and complexity. Aperiodic arrays represent an interesting solution for sharp beam forming, simplification of feed network, and improvement of first side lobe level (FSLL). In this paper, a complete analysis based on variation of distances between elements based on standard aperture distribution coefficients for side lobe reduction is proposed. The procedure relies on varying the locations of the array elements to realize tapering for reduction in interference of wireless communication systems.
