Abstract
An electronic device may be provided with a phased antenna array and a display cover layer. The phased antenna array may include a probe-fed dielectric resonator antenna that radiates through the cover layer. The antenna may include a dielectric resonating element that is excited by one or two feed probes. One or more floating parasitic elements and/or grounded parasitic elements may be patterned onto the dielectric resonating element. The parasitic elements may create boundary conditions on the dielectric resonating element that serve to isolate the antenna from cross polarization interference.
Claims20
An electronic device comprising:
- a housing;
- a display having a display cover layer mounted to the housing;
- and
- a probe-fed dielectric resonator antenna in the housing and configured to convey radio-frequency signals in a frequency band greater than 10 GHz through the display cover layer, wherein the probe-fed dielectric resonator antenna comprises:
- a parasitic element configured to isolate the probe-fed dielectric resonator antenna from cross-polarization interference.
An antenna comprising:
- a dielectric resonating element having a bottom surface, a top surface, and first, second, third, and fourth sidewalls extending from the bottom surface to the top surface, wherein the first sidewall opposes the third sidewall and the second sidewall opposes the fourth sidewall;
- a feed probe coupled to the first sidewall, wherein the feed probe is configured to excite the dielectric resonating element to resonate in a frequency band greater than 10 GHz;
- and
- a floating parasitic patch coupled to the third sidewall and overlapping the feed probe.
