IEEE Transactions on Antennas and Propagation, 1971
A set of arbitrarily located receiving antenna elements, each connected with an appropriate network, can be used to construct a matched filter where the antenna array response results in an autocorrelation of a specified desired signal, correlating over time and space coordinates simultaneously. A receiving system using such a signal processing antenna

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
The architecture of a new type of L-band multiple-beam antenna (ALE 3*5) for air traffic control (ATC) is presented. The electrical performance makes it equivalent to an antenna with very sharp horizon cutoff, large coverage angles, and high gain. The design requirements are as follows: frequency band of 1.25-1.35 GHz: a modular architecture with few ...

6th European Microwave Conference, 1976, 1976
An equivalent network for rectangular shaped microstrip radiating elements is derived. In order to simplify the problem the radiating elements are considered as two slots separated by a transmission line of low characteristic impedance. The slots are characterized by their equivalent admittances.
