“…The free space total and radiation efficiencies of the prototype antennas were computed from the measured (anechoic chamber) 3-D radiation patterns by using the 3-D pattern integration technique [38]. In the results analysis, the widely applied [4], [5], [8], [9], [13], [16], [19]- [23], [26] impedance matching criterion has been used to calculate the impedance bandwidths.…”

Abstract-In this paper, internal low-volume antenna structures for mobile terminals are studied. The work concentrates on the possibilities to reduce the volume of mobile terminal antenna elements by efficiently utilizing the radiation of the currents on the mobile terminal chassis. Essentially nonresonant coupling elements are used to optimally couple to the dominating characteristic wavemodes of the chassis. The antenna structures are tuned to resonance with matching circuits. During the last few years, the approach has achieved growing interest-also among industrial manufacturers of mobile terminals. There exist, however, no systematical feasibility and performance studies of the idea. During the work, two antenna models with very low-volume coupling elements are designed and in total four prototypes are constructed. The simulation and measurement results show that the studied antenna concept is a very promising alternative for traditional antenna technologies. The presented analysis provides useful and novel information for the designs of the future low-profile and low-volume mobile terminal antennas.

“…In this regard, Planar Inverted F Antenna (PIFA) has found internal utilization within the mobile units due to its small size for both single and dual band applications [1][2][3]. The PIFA has many advantages such as easy fabrication with simple structures and low manufacturing cost.…”

In this paper, matched performance of a double band PIFA antenna is reported. The transducer power gain of the antenna is optimized over the commercialized wireless communication bands of 824-960 MHz and 1710-1990 MHz using only one matching network. In the design process, several commercially available computer aided design packages with variety of different matching network topologies were employed. The best result was obtained by using the Simplified Real Frequency Technique, which in turn yields an "easy to implement circuit topology". The matched antenna provides an average transducer power gain of -1.6±0.4 dB in 824-960 MHz and -2.2±0.5 dB in 1710-1990 MHz.

“…The Planar Inverted F Antenna (PIFA) has been used for internal antennas of mobile communication systems due to its various advantages such as easy fabrication, low manufacturing cost, and simple structure [1][2][3][4][5][6][7][8]. But the major disadvantage to keep the PIFA from diverse application is its narrow bandwidth.…”

“…Besides expanding the gap between top plate and ground plane, there are several techniques applied to PIFA to broaden the bandwidth. In principle, the broad bandwidth or bandwidth enhancement of PIFA can be achieved by several efficient approaches; using a dual resonance phenomenon by additional patch [3], loading a dielectric material with high permittivity [4], and attaching a chip resistor [5]. But these methods need an additional element.…”

In this paper, we present a new compact Planar Inverted F Antenna (PIFA) applicable to PCS system. The principle aim in design is to broaden the bandwidth. To overcome the narrow bandwidth characteristic, that is typical of a patch antenna, a type of tapered patch is employed. In specific case, bandwidth of about 15.2 % was achieved experimentally. And when the tapered type PIFA was applied to a specially designed mobile phone structure, the Specific Absorption Rate (SAR) value was less by 40% than that of the conventional structure.
