Definitions
- the invention relates to a PIFA antenna device (Planar Inverted F-Antenna), with an RF input / output and two antenna areas, each of which has contact with a ground of a mobile communication terminal, the first antenna area for two independent frequencies and the second antenna area is designed for a third independent frequency.
- PIFA antenna device Plant Inverted F-Antenna
- the antenna should meet both technical and optical requirements. On the one hand, it should work for more than one frequency, on the other hand, it should be as small as possible, for example to allow integration into a mobile radio device that is invisible from the outside.
- a PIFA antenna Planar Inverted F-Antenna
- PIFA antenna Planar Inverted F-Antenna
- GSM Global System for Mobile Communication
- PCN PCN
- PCN Personal Communication Network
- a known embodiment for introducing a third frequency provides for the bandwidth of the PCN frequency band of a dual-band antenna to be increased by increasing the distance between the antenna and the printed circuit board (PCB board) of the mobile radio device.
- PCB board printed circuit board
- the GSM / PCN dual-band antenna can also be used for the PCS frequency band.
- the PIFA antenna requires approximately 50% more volume for operation on three frequency bands than a PIFA antenna which only operates on two frequency bands.
- Another embodiment of designing a PIFA antenna that operates on three frequency ranges provides for combining a dual-band PIFA antenna with an additional antenna.
- This additional antenna provides the third resonance frequency and the entire PIFA antenna device now has three frequencies.
- both the dual-band PIFA antenna and the additional antenna are connected to an RF input / output of the mobile radio device, with both antennas being controlled separately. This configuration also leads to a larger volume of the PIFA antenna device.
- the inventor proposes a PIFA antenna device with an RF input / output and two antenna areas, each of which has contact with a ground of a mobile communication terminal, the first antenna area for two independent frequencies and the second antenna area for a third independent Frequency trained is to be further developed in such a way that only the first antenna surface is connected to the RF input / output and the second antenna surface is arranged without contact with the first antenna surface in such a way that an electromagnetic coupling is created between the two antenna surfaces.
- This electromagnetic coupling eliminates the need to separately control the second antenna area.
- the first antenna area can operate as a dual-band antenna in the frequency bands for GSM and PCN operation and the second antenna area can provide the frequency for PCS operation.
- the second antenna surface is designed such that it forms a ⁇ / 4 resonator when it is connected to ground.
- the ⁇ / 4 resonator is excited by an electromagnetic coupling between the two antenna surfaces.
- the length and the width of the second antenna area can advantageously be matched to a desired third frequency.
- a nominal value of, for example, 50 ohms input impedance of the antenna device at the third frequency can be realized by selecting the size of the free area or the non-conductive medium between the two antenna areas.
- the antenna can be operated without a matching network or with a small number of matching elements, so that the losses occurring in matching circuits can be avoided.
- the antenna surfaces have kinks and bends. This can result in small spatial structures that are suitable for use at two as well as three frequencies and that can adapt to a housing of an existing mobile radio device.
- a first surface is provided which is largely enclosed by the first antenna surface and the second antenna surface is arranged within this surface. This configuration has the effect that the second antenna area can be accommodated in a recess in the interior of the first antenna area without requiring additional space.
- the two antenna surfaces can preferably be arranged in one plane (coplanar).
- the area delimited by the first antenna area can have a rectangular shape.
- This area is preferably adapted to the length and width of the second antenna area such that a contactless arrangement of this second antenna area as well as an electromagnetic coupling between the two antenna areas is made possible.
- the medium between the two contactlessly arranged antenna surfaces is preferably air or another non-conductive medium.
- the PIFA antenna device in an advantageous embodiment of the PIFA antenna device according to the invention, at least one second area or recess is provided, which is delimited by the antenna area. In this way, the third frequency of the PIFA antenna device according to the invention can be tuned independently.
- Figure 1 PIFA antenna device according to the invention
- Figure 2 calculated reflection coefficient Sn of the PIFA antenna device according to the invention.
- FIG. 1 shows a preferred exemplary embodiment of the PIFA antenna device A according to the invention.
- Antenna device A contains two antenna areas Pl and P2, the antenna area Pl largely delimiting or comprising a rectangular area FI.
- the antenna area Pl is open on one side.
- the area FI can also be viewed as a recess in the antenna area Pl and can also have a different shape.
- the antenna area Pl contains a contact Gl, which contacts a mass of the mobile radio device, an RF input / output S1, which connects the antenna area Pl to an RF input / output of the mobile radio device, and a further area or a recess F2.
- the antenna area Pl represents a dual-band antenna, for example for the frequency bands 900 MHz and 1800 MHz.
- a further antenna area P2 is arranged in the cutout F1 without additional space being required. It should be noted here that the antenna surfaces P1 and P2 do not touch each other.
- the antenna area P2 has no direct connection to the RF input / output S1, so that it represents a "parasitic element".
- the antenna area P2 carries a contact G2, which connects the antenna area P2 to the mass of the mobile radio device. If the antenna surface P2 is connected to the ground, it forms a ⁇ / 4 resonator, which only requires half the surface of a ⁇ / 2 resonator (without a ground connection).
- the third frequency band can be selected by the selected length and width of the antenna area P2.
- the antenna area P2 is excited via an electromagnetic coupling between the antenna area P1 and the antenna area P2.
- an optimal reflection coefficient Su can be realized at a third frequency.
- FIG. 2 shows as a solid line the reflection coefficients Sn of the PIFA antenna device according to the invention, which were calculated in a known manner, plotted against the frequency F.
- the frequency bands for the GSM operation in the range between approximately 880 to 960 MHz, for the PCN operation in the range between approximately 1710 to 1880 MHz and for the PCS operation in the range between approximately 1850 to 1990 MHz are shown as dashed lines .
- the simulation results plotted in FIG. 2 show that the PIFA antenna device according to the invention meets the requirements for operation in these three frequency ranges.
- the invention presents a PIFA antenna device for three frequency ranges, the dimensions of which correspond to those of a dual-band PIFA antenna and which enables installation in existing mobile radio devices.
