Ultra-wideband Antenna Having Fed and Unfed Arms - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240021986 titled 'Ultra-wideband Antenna Having Fed and Unfed Arms

Simplified Explanation

The patent application describes an electronic device with an antenna that includes a ring of conductive traces, a fed arm, and an unfed arm. The fed arm and the unfed arm extend from opposing segments of the ring, which is coupled to ground by fences of conductive vias. The first arm has a first radiating edge, and the second arm has a second radiating edge, separated by a gap. The first arm indirectly feeds the second arm via near-field electromagnetic coupling across the gap, allowing both arms to collectively radiate in an ultra-wideband (UWB) frequency band.

• The antenna includes a ring of conductive traces, a fed arm, and an unfed arm.
• The fed arm and the unfed arm extend from opposing segments of the ring.
• The ring is coupled to ground by fences of conductive vias.
• The first arm has a first radiating edge, and the second arm has a second radiating edge.
• The first and second arms collectively radiate in an ultra-wideband (UWB) frequency band.
