Custom Coils has manufactured <a href=\"https:\/\/www.customcoils.com\/antennas-and-air-coils\/\">antenna coils<\/a> for many years, in a wide range of styles, shapes, and sizes. Its coils are used in military, oil and gas, and industrial instrumentation environments, among others. Because each coil starts from your application requirements, the electromagnetic coil design can follow your electrical and mechanical needs rather than a catalog part.<\/p>\n\n\n\n<h2>Core Specifications to Define<\/h2>\n\n\n\n<p>Four parameters shape most custom antenna coil designs:<\/p>\n\n\n\n<ul><li><strong>Turns count:<\/strong> Custom Coils produces antenna coils with high turns counts, including with fine gauge wire.<\/li><li><strong>Conductor type:<\/strong> Choose the wire to suit your current and winding requirements.<\/li><li><strong>Inductance:<\/strong> State the target value the finished coil must meet.<\/li><li><strong>Size and shape:<\/strong> Custom-shaped coils can be wound up to 2.5 ft x 3 ft, and coil lengths run from 3 to 24 inches.<\/li><\/ul>\n\n\n\n<p>For high-frequency antenna coils and custom RF coils, also share your operating frequency range and tolerance expectations. This lets the engineering team review them against the design before production begins.<\/p>\n\n\n\n<h2>Choosing a Construction Style<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Self-supporting air coils are a core product, available with fine gauge wire and high turns counts. Custom Coils also winds with bondable wire, which it says allows it to meet almost any operating current requirement. Bonded coils are an alternative to bobbin-wound coils and perform better in certain applications. Where a core is needed, ferrite antenna coils have been used extensively, including in RFID. If you are weighing options, <a href=\"https:\/\/www.customcoils.com\/air-core-inductors\/\">air core inductors<\/a> are a related product line.<\/p>\n\n\n\n<h2>Materials and Environmental Protection<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Antenna coil winding materials include steel, PVC, and ferrite, sourced from approved suppliers. Reliable insulation tapes and epoxies protect custom-wound antenna coils from physical and environmental hazards. Describe the operating environment in your request so material and protection choices can be matched to it.<\/p>\n\n\n\n<h2>How Antenna Coil Winding Works<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Precision starts with tooling. Custom Coils uses an extensive range of arbors and winding mandrels, and develops new ones in-house when a project needs a shape it does not already have. Its winding machines and techniques allow even high-turn-count coils to be wound to a given specification. That tooling depth is central to antenna coil manufacturing for non-standard geometries.<\/p>\n\n\n\n<h2>Verifying Quality<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Every coil is tested. Custom Coils performs 100% testing on all coils, using Voltech AT3600 Transformer Testers to check specifications such as inductance and resistance. The company is also ISO 9001 certified, with documentation available on request.<\/p>\n\n\n\n<h2>What Engineers and Purchasing Teams Should Align On<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Engineers should supply the dimensional drawing, turns count, conductor type, and inductance target. Purchasing teams should confirm quantities, delivery expectations, and any documentation requirements, such as the ISO 9001 certificate. Settling these points up front helps both groups evaluate a quote on the same basis and keeps the project moving.<\/p>\n\n\n\n<h2>Where Custom Antenna Coils Are Used<\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Typical applications include RFID, security, transportation and traffic control, warehouse automation, industrial process control, tire pressure monitoring receivers, automotive and in-home security systems, avionics, and military uses.

A design that pairs an antenna coil with power or drive circuitry may also need a <a href=\"https:\/\/www.customcoils.com\/single-phase-transformer\/\">single phase transformer<\/a>, an <a href=\"https:\/\/www.customcoils.com\/inverter-transformers\/\">inverter transformer<\/a>, or a <a href=\"https:\/\/www.customcoils.com\/flyback-transformers\/\">flyback transformer<\/a>.
