Wideband Phased Array Antennas
2008 IEEE National Aerospace and Electronics Conference, 2008Slotted spiral antennas with a ground plane are designed to cover the frequency range 0.5-18 GHz. Various antennas incorporating Archemidan slotted spirals with a ground plane and dielectric thickness less than 100 um were designed, processed and tested at different frequency ranges using conventional PCBs as well as vertically interconnected and ...

1971 2nd European Microwave Conference, 1971
The theory of array antenna design has matured such that the tools are now available to design elements with predictable performance and to verify this performance with high confidence. The antenna feed is of equal importance to the antenna element.

IEEE Transactions on Antennas and Propagation, 1964
A self-phasing array antenna is described which operates on the incident wavefront in such a manner that when it is retransmitted it returns whence it came as a coherent wavefront irrespective of the original phase distribution incident on the array. Self-phasing is useful where a two-way propagation path is available and where a conventional antenna ...

Conformal Phased Array Antenna Design
S-MTT International Microwave Symposium Digest, 1974An extremely low profile modular conformal phased array antenna design will be presented. Components that make up the antenna will be described to show the unique features such as the plug-in balun, the MHP phase shifter assembly, and the stripline RF manifold tracks incorporated to a create a lightweight, reliable, maintainable panel.

This paper demonstrates and compares the Planar arrays (2D) and the Conformal arrays (3D). The 3D surfaces and topography of these applications have allowed for more frequent and high scale design. Analysing conformal antennas are a technology that has been utilized for electromagnetic emitting devices.
