The magnetic field or magnetic loop antenna is the name of this antenna. The magnetic field (H-field) coming from the EUT is measured using the magnetic loop antenna.
When RE testing below the typical 30 MHz lower frequency point is mandated by the product standard, measurement of the H-field is frequently specified.
A structure that can emit electromagnetic radiation into a medium is what it is, to put it simply. For instance, an antenna that produces a plane wave is an infinite sheet of current.
The basic idea is rather straightforward: An antenna must deliver a time-dependent current that creates both an electric and magnetic field.
The region around a magnet where the effects of magnetism are felt is known as the magnetic field. To describe how the magnetic force is dispersed in the area around and inside something magnetic in nature, we utilise the magnetic field as a tool.
The region with magnetic force surrounding a magnet is called the magnetic field. There are north and south poles on every magnet.
The same poles repel one another whereas opposite poles are drawn to one another. The north-seeking poles of the iron’s atoms line up in the same direction when it is rubbed against a magnet. Electrically charged particles are forced to move in a circular or helical pattern by magnetic fields.
The Global Magnetic Field Antenna market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The market’s best Middle-Range Antennas for LF emitter antennas for Automotive RFID are the KGEA-MRHPM Series, which also has improved mechanical and electrical performance.
The majority of KES-equipped vehicles now being produced use many short antennae. 3 to 6 antennae are utilised in the door handles, interior, trunk, and/or bumper positions depending on the size of the automobile and the system quality.
The automotive side is being forced by current technological developments to lower the number of antennas in order to optimise electrical and mechanical performance.
Because of this, overcomes the technological difficulties, preserving all the benefits of mid-range antennas while maintaining the cost-effectiveness, mechanical robustness, and thermal stability of short-range antennas.
When you require an antenna with strong mechanical loads and IP69K-rated waterproof protection, choose this one (inflection, torsion and drop tests).
The portion is completely wrapped in thermoplastic HPM (High Pressure Molding) technology using a PREMO-patent method where there is no point of union between various plastics (bobbin and final over-molding), providing a fully waterproof antenna.
Another solution offered by this antenna is its built-in connector, which eliminates the need for external connectors and ASSY cables while lowering the BOM and simplifying assembly. It is included into the HPM over-molding process.
