A device may include an oscillator circuit whose frequency of operation is determined by a resonant frequency of a tank circuit and reactance of a load associated with the antenna terminal configured to receive an external antenna. A controller may be configured to measure an output signal of the oscillator circuit when the oscillator circuit is connected to the antenna terminal, and determine whether or not the external antenna is connected to the antenna terminal based on the measurement and comparison data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna assembly detection based on oscillator and variable reactance tank circuit","description":"A device, a method, and a non-transitory storage medium are described in which an antenna assembly detection service is provided.
