Abstract
A cavity-backed slot antenna is disclosed that includes a stripline. The stripline includes a conductive strip between two ground planes separated by a dielectric. The conductive strip feeds the cavity-backed slot antenna. The stripline also includes a first segment and a second segment. The first segment has a first characteristic impedance. The second segment is proximate the cavity-backed antenna and has a second characteristic impedance different than the first characteristic impedance. The second characteristic impedance provides impedance for matching a load impedance of the cavity-backed slot antenna.
Claims20
A device comprising:
- a cavity-backed slot antenna;
- and
- a flexible planar transmission line to feed the cavity-backed slot antenna, the flexible planar transmission line including:
- a conductive strip separated from one or more ground planes by a dielectric, wherein the conductive strip feeds the cavity-backed slot antenna,
- a first segment having a first characteristic impedance, and
- a second segment, proximate the cavity-backed antenna, having a second characteristic impedance, wherein the second characteristic impedance provides impedance for matching a load impedance of the cavity-backed slot antenna.
A device comprising:
- a display having a housing and a bezel;
- a cavity-backed slot antenna situated within the bezel;
- and
- a flexible planar transmission line to feed the cavity-backed slot antenna, the flexible planar transmission line including:
- a conductive strip separated from one or more ground planes by a dielectric, wherein the conductive strip feeds the cavity-backed slot antenna,
- a first segment having a first characteristic impedance, and
- a second segment, proximate the cavity-backed antenna, having a second characteristic impedance, wherein the second characteristic impedance provides impedance for matching a load impedance of the cavity-backed slot antenna.
