RF COMMUNICATION DEVICE AND METHOD OF OPERATION OF THE DEVICE

摘要

An RF communication device (100) includes a radiating member comprising an electrically conducting portion having therein a first slot (123) operable as a slot RF radiator, wherein the radiating member comprises at least part of a casing (103) of the device. The device may further include a feed member such as a circuit board (101) for feeding RF signals to and from the radiating member, the feed member having an electrically conducting area (201) forming at least part of a radiator ground plane. The electrically conducting area may have a gap (203) therein providing a second slot operable to provide RF energy coupling with the first slot. The device may further include, attached to the radiating member, a dielectric member (105), e.g. a dielectric cap, which in operation increases the electrical length, compared with the actual length, of at least the feed member.
