Embodiment Construction

[0045]The invention generally described relates to a multi-band antenna for a wireless mobile communication device, such as a cellular handset. The antenna may comprise a bifurcated ring structure along one, two, three or all four edges of the device. The annular structure may comprise bifurcated metal conductors or strips extending along the length of the one or more edges. A first of said strips on said one or more edges may be adjacent to a first major planar surface of said device, a second of said strips on said one or more edges A strip may be adjacent to the second major planar surface. A dielectric material may be located on the one or more edges between the pair of furcation bars. In an embodiment, the pair of furcation bars on the edge may be electrically coupled to each other by means of a connector embedded below the dielectric material to ensure that the furcation bars on the edge The strips are symmetrical in appearance.

[0046] As noted above, the bifurcate...

Abstract

A multiband antenna is disclosed for wireless mobile communication devices such as cellular telephones. The antenna may include a bifurcated ring structure along one, two, three or all four edges of the device. The ring structure may include bifurcated metal conductors, or bars, extending along the length of the one or more edges.

Description

[0001] This application claims prior application priority to U.S. Nonprovisional Patent Application Serial No. 15 / 835,150, filed December 7, 2017, entitled "A Bifurcated Multimode Loop Antenna for a Wireless Communications Device," The content of this prior application is incorporated herein by reference. technical field [0002] The present technology relates to transmission and reception of radio waves, and in particular, to an antenna provided on an edge of a wireless communication device. Background technique [0003] Wireless devices connect to wireless networks by means of antennas in a variety of frequency bands. An antenna is a medium used to send and receive electromagnetic waves. Antennas for portable wireless devices such as mobile phones can be tuned to various frequencies. Currently, low bands are in the range between 698MHz and 960MHz, mid / high bands are in the range between 1427MHz and 5GHz, eg 2G GSM bands (850 / 900 / 1800 / 1900MHz), 3G UMTS bands 5 / 2 / 1 (850 / ...
