Dual-band inverted slot antenna

摘要

Methods and systems for radiating electromagnetic energy with a dual-band inverted slot antenna are described. The dual-band inverted slot antenna may be formed of a metallic member with two open ends at one or more edges of the metallic member. The inverted slot antenna is configured to radiate electromagnetic energy in response to the RF signal at two resonant modes.

1. An electronic device comprising:
a circuit board comprising a transceiver and a ground plane; a radio frequency (RF) feed coupled to the transceiver; and an inverted slot antenna comprising a slot opening in the ground plane and a ground stub, wherein the slot opening comprises: a middle portion, a first side portion, and a second side portion, wherein the first side portion extends to an edge of the ground plane to cause a first open circuit when the inverted slot antenna is radiating and the second side portion extends to the edge to cause a second open circuit when the inverted slot antenna is radiating, wherein the ground stub extends out from the middle portion to cause a short circuit when the inverted slot antenna is radiated, wherein the RF feed is disposed in the middle portion to feed the inverted slot antenna.
