Design and Analysis of Star Spiral with Application to Wideband Arrays with Variable Element Sizes
… the advantages of the star spiral when used in a wideband array with variable element sizes. The wideband array with variable element sizes (WAVES) is a multi-octave array that uses different sized circular Archimedean spirals for each octave of frequency coverage. A two-octave WAVES array has …

Wideband Low-Profile Antenna Arrays: Fundamental Limits and Practical Implementations
… high performance, compact antennas. Low-profile wideband phased arrays are of particular interest, and have recently been shown to be capable of extremely large bandwidths. However, the size, weight, and cost of phased arrays still makes them impractical for many applications. The development of …

Characteristic mode theory for closely spaced dipole arrays
Applications of antenna arrays, such as radar, benefit significantly from an array with wide operational bandwidth. In order to create these arrays, designers have traditionally relied on arraying relatively wideband antennas. Recently, planar arrays utilizing narrowband elements have been shown to …

Synthesis of Ultra-Wideband Array Antennas
Acquisition of ultra-wideband signals by means of array antennas requires essentially frequency-independent radiation characteristics over the entire bandwidth of the signal in order to avoid distortions. Factors contributing to bandwidth limitation of arrays include array factor, radiation …
