Definitions
- a hearing aid such as a behind the ear hearing aid
- a transceiver for wireless data communication interconnected with an antenna, such as an electric antenna, for emission and reception of an electromagnetic field.
- the antenna may extend on a first side of the hearing aid and a second side of the hearing aid.
- a first segment of the antenna may extend from proximate the first side of the hearing aid to proximate the second side of the hearing aid and a feed system may be provided for exciting the antenna to thereby induce a current in at least the first segment.
- the antenna may emit a substantially TM polarized electromagnetic field for diffraction around the head of a user, i.e. TM polarised with respect to the surface of the head of a user.
- the first and second resonant structures may be resonant around a center frequency, i.e. around the resonance frequency for the antenna, and typically, the resonant antenna structure may be resonant within a given bandwidth around the center frequency.
- the point with reference numeral 2 in Fig. 1 furthest to the left on the surface of the head in Fig. 1 has tangential vectors parallel to the yz-plane of the coordinate system, and a normal vector parallel to the x-axis.
- the y-axis and z-axis are parallel to the surface of the head at the point 2 and the x-axis is orthogonal to the surface of the head at the point 2.
- the user modeled with the phantom head of Fig. 1 is standing erect on the ground (not shown in the figure), and the ground plane is parallel to xy-plane.
- the torso axis from top to toe of the user is thus parallel to the z-axis, whereas the nose of the user is pointing out of the paper along the y-axis.
- a hearing aid 30 is shown schematically, wherein the width 45 of the first part 40 of the antenna 37 and the second part 41 of the antenna 37 is increased to increase the bandwidth of the antenna 37.
- Fig. 6 shows a further embodiment of the invention, wherein the hearing aid 30 has an antenna 37 having a first part 61 and a second part 62.
- the first part 61 and/or second part 62 are closed antennas having a width 63 allowing for an opening 64 to be formed within the antenna 37.
- the opening may allow for configuring the antenna so as not to extend over battery 31 and other larger electrical components.
- the first part 61 and/or the second part 62 may have any width and/or any shape configured according to hearing aid restrictions and/or antenna optimization.
- the circumference of the first and/or second parts 61, 62 is approximate lambda/2, where lambda is the resonance wavelength for the antenna 37.
- FIGs. 8a-e schematic antennas 80 are shown, illustrating the feed points 83, 84 and the length of the first and second parts 40, 41, 61, 62 and the distances ⁇ between the feed points 83, 84 and the short circuit.
- the distance ⁇ along the first part 85 between the first feed point 83 and the short circuit 89 is tailored to the desired impedance for the antenna, and the length I of the first part 85 is measured from the short circuit 89 to the free end of the antenna 90 and is lambda/4 in order for the first part to form a resonant antenna structure.
- the distance ⁇ along the second part 86 between the second feed point 84 and the short circuit 89 is tailored to the desired impedance for the antenna, and the length I of the second part 86 is measured from the short circuit 89 to the free end of the antenna 91 and is lambda/4 in order for the second part to form a first resonant structure.
- the first resonant structure 85 is actively fed in the feed point 83 and second resonant structure 86 is actively fed in the feed point 84.
- Fig. 8e shows an embodiment having a closed antenna structure 80 having a first part 95 and a second part 96.
- the length of the first and second closed part is lambda/2 to obtain a resonant structure.
- the widths of the first part 95 and the second part 96 may be tailored according to a desired antenna impedance.
- Figs. 10a-d shows the current along an antenna 40, 80.
- the current is seen to be zero at the free ends 90 of the antenna. It is furthermore seen that the maximum current is found along the first segment or the conducting segment 42, 89.
- Fig. 10a showing a wide BTE hearing aid, that is a relatively long current bridge or first segment, the current exhibits two local maxima at each side of the short circuit with a slight decrease towards the middle.
- the BTE hearing aid is a narrow hearing aid
- the current may as shown in Fig. 10c , be substantially constantly high across the short circuit or the first segment.
- the current is maximized in a direction being substantially orthogonal to the side of the head.
