This book is the result of close cooperation between industry and academia, notably Ericsson
and two universities in Sweden: Chalmers University of Technology (CTH) in Göteborg
and The Royal Institute of Technology (KTH) in Stockholm. In 1987, a student at
CTH presented her PhD thesis on the topic of conformal antennas. It was then considered
an interesting but difficult technology with no immediate application.
The essential constituent of a conformal array is curvature. Authorities disagree on whether the array must be part of a curved metallic structure; in this chapter curvature alone is sufficient. Arrays of one or more concentric rings of elements, here called “ring arrays,” are treated first. The term “circular array” is not used, as it often means a planar array of circular perimeter. The following sections deal with arrays on curved metallic bodies. Most simple is the cylinder; Section 11.3 treats cylindrical arrays with elements around the full circumference....

Introduction to Computing: Lecture 9 includes about Data Structures is essentially a number of data items, with some relationships among them. It includes Arrays, Stack, Queue, Circular queue, Linked list, Binary tree.
Many aircraft radars are now equipped with flat plane slot arrays instead of dish antennas, where the outline is approximately circular. These are usually fixed narrow-beam antennas with controlled sidelobes. Pattern synthesis typically usesthe product of two linear syntheses;one along the slot “sticks,” and a second across the sticks. These are often designed as Taylor ii patterns, as described in Chapter 3. Since the sticks near the edge are shorter, with fewer slots, than those at the center, the overall pattern will deviate somewhat from the product of the two orthogonal patterns...
