An Antenna has two complementary functions: converting electromagnetic waves into voltage and current used by a circuit, and converting voltage and current into electromagnetic waves that are transmitted into space. It can be passed through substratists for support and/or outlet purposes, or it can be used as a contact on a printed circuit board. Thin metal antennas can be produced to perform in highly critical electronic applications.

E-Fab has been building antennas for our customers since 1981. Our processes ensure tight tolerances can be held to meet your specifications. This has made E-Fab a preferred antenna supplier for industry leaders. Our experience includes manufacturing cones, horns, helixes, spirals, microstrips, arrays, fractals, rigid, and flexible antennas.

Antenna Substrate Thickness

E-Fab works most with Duroid laminates, polyimide, Teflon, and ceramic substrates, which have better electrical impedance, thermal, chemical, and mechanical properties. The antennas we build are typically designed and built on substrate thicknesses from 0.0005 to 0.0006 inches (0.127-1.52 mm), with some designs requiring a thickness of up to 0.250 inches (6.35 mm). These substrates are copper clad, single or double-sided, with 1/4 oz., 1/2 oz., 1 oz., and 2 oz. copper. Double-sided substrates are commonly used for microstrip antenna ground planes.

Applications and Industries

E-Fab has almost 40 years of precision etching antenna experience for applications, including

  • Microstrip antenna ground planes
  • Space borne antenna
  • Large format antennas
  • Phased arrays
  • Miniature parabolic

These parts are ideal for industries including aerospace, military and defense, commercial electronics, and communications. We customize and manufacture microstrip antennas on the following substrate materials:

  • Duroid laminates
  • Polyimide
  • Kapton
  • Teflon
  • Ceramics

Antennas are commonly manufactured from copper, and can be custom ordered from any metal E-Fab photochemically etches. Once the PCM process is completed, the etched antenna can be electroplated with various metals or alloys such as tin nickel or gold.
