Stripline radiators

The application off etching and printing techniques to electronic circuits makes feasible the construction of microwave strip antenna arrays both From practical and economical viewpoints. Many conventional broadside curtains used at lower frequencies were impractical to fabricate in the region above 1000 Mc. Progress in the design of strip conductors as microwave antennas indicates that many of these arrays can now be adapted for operation at microwaves and fabricated with sufficient accuracy to be truly useful. Some of the components involved in the design of strip antennas, such as balanced lines, twists, baluns and power dividers have been investigated. Complete strip arrays consisting of up to 80 elements have been tested. The gain, bandwidth, and radiation patterns appear comparable with those obtained from the corresponding arrays used at the lower frequencies for which the same theory of operation applies.
