“…In some situations, the ground plane cannot be enlarged due to mechanical requirements given by the phone manufacturer. In those cases, if the bandwidth needs to be improved, some techniques adding intelligence in the ground plane can be used such as for example adding slots in the ground plane [2][3][4][5][6][7][8][9][10][11][12] or adding metallic strips [13][14][15][16][17]. As an example, the proposed method is used here to give a physical insight into the behavior of adding metallic strips to a ground plane having 100 mm length (Fig.…”

“…In this regard, handset antennas operating in the frequency region of 698-960 MHz where some standards are allocated (LTE700, GSM850/900), would require a ground plane length of 144.7 mm (computed at 829 MHz), which is too long for many devices. To solve this size limitation, some authors have proposed mechanisms to electrically enlarge the ground plane by using slots or metallic strips to better excite its radiation mode, and as a consequence, larger bandwidth and efficiency are obtained [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

Abstract-The ground plane of wireless handheld devices plays a significant role in the electromagnetic behavior determining bandwidth, efficiency, and radiation patterns. Therefore, it is necessary to determine the frequency region where the ground plane can be better excited, especially for low frequencies where the performance of the radiating system is critical due to size limitations with respect to the operating wavelength. A fast method based on the radar cross section (RCS) is presented for computing the frequency at which the ground plane is better excited. The proposal is applied to three typical wireless platforms: a handset phone, a smartphone, and a clamshell phone. The method is compared with characteristic mode analysis and the results demonstrate a very good agreement in the resonant frequency prediction. In addition, complex platforms using metallic strips and slots in the ground plane are analyzed using RCS which gives physical insight into the electromagnetic performance.

“…In some situations, 120 mm may be too large for a handset phone. Therefore some researchers propose to electrically enlarge the ground plane by adding slots on the ground plane [4][5][6][7][8][9][10]. As a result, handhold and head proximity degrade antenna performance.…”

“…This is mainly due to their miniature size, easy fabrication, and low cost [2,3]. To achieve a wide bandwidth in the GSM850/900 band, the system ground plane of a PIFA or IFA acts as part of the antenna, thereby improving the bandwidth and gain performance [4][5][6][7][8][9]. This is necessary, especially as the mobile device is quite small.…”

Abstract-This paper presents a multiband folded loop antenna for smart phone applications.The proposed antenna with a symmetric loop pattern generates four resonance modes in the design bands. The current distributions of the excited resonance modes are analyzed to confirm the mode characteristic. Using a pair of tuning elements near the feed port, the impedance bandwidth is broadened to cover GSM850/GSM900/DCS/PCS/UMTS bands. This research performed simulation by a high frequency structure simulator (HFSS) to optimally design the antenna, and a practical structure was constructed to test. The current study measured the antenna parameters including reflection coefficient, radiation characteristics, peak gain, and radiation efficiency to validate the proposed antenna.

Abstract-The development of compact antennas plays an important role in the rapidly growing mobile communication market. This paper presents a novel design technique of the quad-band small internal antenna covering GSM-900/DCS-1800/PCS-1900/IMT-2000 bands. The innovative quad-band built-in handset antenna is developed within the limit of a 44×25×4 mm 3 volume. The following document describes a new idea of increasing operational bandwidth for the compact planar inverted F antenna (PIFA). The proposed compact antenna introduces the open-end slots in the ground plane almost all under the radiating patch. The size reduction method is attractive for practical antenna implementations. In addition, the end user's hand handling effects on the performances of the proposed antenna are studied.
