A novel and practical approach is presented providing improved antenna performance without enlarging the antenna or the ground plane.
The approach electrically extends the ground plane using wire(s) that behave as surface metal extensions of the ground plane.
The wire extensions can be accommodated within typical handset housing or as part of the stylish metal used on the handset’s exterior perimeter; hence don’t require enlargement of the device.
Consequently, this approach avoids the costs and limitations traditionally associated with physically lengthening of a ground plane.
Eight variations are presented and compared with baseline antenna performance.
Both far-field patterns and near-field electromagnetic scans demonstrate that the proposed approach controls the electrical length of the ground plane and hence its chassis wavemodes, without negatively impacting the characteristics of the antenna.
Improvements in performance of up to 56% in bandwidth at 900 MHz and up to 12% in efficiency with a reduction of up to 12% in the specific absorption rate (SAR) are achieved.
An 8% increase in efficiency with a 1.3% improvement in bandwidth and a 20% reduction in SAR is achieved at 1880 MHz.
Thus, improvements in bandwidth are achieved without compromising efficiency.
Further, improvements at lower frequencies do not compromise performance at higher frequencies.
