Problems solved by technology

The downside of this solution is that two antennas require more physical space in an already crowded small portable device
Also, the device is more expensive and complex from the standpoint of having two separate radiators, feed clips, matching parts, coaxial cables, etc.
Also, if one of the transmit antennas is on the top of the phone, this can create a very difficult specific absorption rate (SAR) problem

Embodiment Construction

[0027] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are illustrative only, and do not limit the scope of the invention.

[0028] Embodiments include multi-band antennas for electronic devices such as portable wireless communication devices. Example wideband / broadband antenna designs cover 690MHz to 960MHz with various communication protocols listed below: LTE Band XVII, Band XIII, GSM850, GSM900, UMTS Band5, Band XII, Band8 for low band and for high band 1700MHz to 3000MHz (LTE Band IV, Band2 / 1 / 4 / 41, DCS1800, PCS1900) or 1400MHz to 2700MHz (Band XI, Band 41), depending on the mode of antenna optimization and tuning. While specific frequency bands are listed because they are currently used for wireless communications, the embodiment...
