Antenna with effective and electromagnetic bandgap (EBG) media and related system and method

摘要

An apparatus includes an antenna (102a-102d, 200) having multiple layers (212-226). At least a first of the layers includes both an effective medium (216-218) and an electromagnetic bandgap (EBG) medium (220-226). The antenna could include a ground plane (206) and a feed line (202), and the first layer of the antenna can be located between the ground plane and the feed line. The antenna could also include a slot ground (204) and a planar antenna structure (208), and the first layer of the antenna could be located between the slot ground and the planar antenna structure. The antenna could further include a first substrate (212) between a feed line (202) and a slot ground (204) and a second substrate (214) covering a planar antenna structure (208), and the first layer could include one of the first and second substrates.
