The interaction between handset antennas and biological tissues, quantified by the specific absorption rate (SAR), is explained.

It is an object of the present paper to provide an overview of the evolution that wireless handheld technology has experienced in the last years. In this sense, a description of the evolution of wireless handheld devices, regulations, challenges in today’s smartphones, and handset characterization are reviewed. Finally, recent advances in antenna technology for wireless handheld or portable devices are presented.

developed for end-of-the-line manufacturing testing of
fully-assembled wireless devices. The system concept uses a
phased array of antennas placed inside an RF shielded
enclosure. It takes advantage of the multi-path
environment inside the enclosure to adapt itself to create a
static channel environment with the specified requirement
needs. There are many advantages of the proposed system
over conventional ones, including its adaptiveness to create
a suitable test condition for any device’s antenna type to
improve factory test efficiency for testing devices capable
of performing either single-stream or multi-stream
technologies such as MIMO.

The uniqueness of the proposed antenna (patent pending) is the ease of configuring it for various wireless commercial needs by adjusting its structure parameters. Indeed, the antenna can be used for applications that require bandwidth from GPS to Bluetooth bands. It can also be configured for dual-band systems requiring the 1800-2500 MHz and the 5-GHz UNII bands, or just the two narrower unlicensed bands (2.45 and 5.25 GHz) for WLAN.
