An Antenna

A sinuous and/or log-periodic antenna comprising:

• a relatively flexible dielectric substrate carrying multiple conductive antenna elements, the dielectric substrate being mechanically supported on a relatively rigid former;
• wherein the dielectric substrate defines a common region and arms, and each arm being separately joined to the common region about a separate join;
• wherein each arm provides a first curved surface carrying one of the multiple conductive antenna elements;
• wherein the common region provides a first planar surface carrying conductive traces for connecting each conductive antenna element to a transmission line;
• and
• wherein the dielectric substrate includes a single integral piece defining the common region and the arms, the single integral piece carrying a patterned metallic layer providing the multiple conductive antenna elements and the conductive traces.

A method of manufacturing an antenna laminate for a sinuous or log-periodic antenna, the method comprising:

• providing a metallic layer on a dielectric substrate to form a laminate;
• removing metal from the substrate to define separate conductive antenna elements;
• and
• cutting the laminate such that the antenna laminate defines a common region and separate arms, each of the separate arms being joined to the common region;
• each arm carrying one of multiple conductive antenna elements for the antenna.
