Johanson Technology 7987AT45A0200001E 7987MHz RF Ceramic Patch Antenna
Johanson Technology 7987AT45A0200001E 7987MHz RF Ceramic Patch Antennas are miniature RF ceramic chip antennas featuring an operational frequency of 7987MHz ±100MHz. Johanson 7987AT45A0200001E antennas operate in Ultra-Wideband (UWB) Channel 9 for ranging and radar applications. These RF ceramic patch antennas are manufactured using Low-Temperature Co-fired Ceramic (LTCC) technology, which enables the embedding of both low and high dielectric constants within the antenna. This enables the series to exhibit high detuning resilience and stability over extreme temperatures (~2ppm).
