This paper presents a miniaturized impulse radio ultra-wideband (IR-UWB) antenna which is designed for transcutaneous, short-distance data communication used in multi-channel neural recording. In these systems, with the increasing number of recording channels, data rates of 10-100 Mbit/s must be transmitted with very limited power and area. Therefore, the antennas are designed as planar, ellipsoidal dipoles on a high permittivity substrate with epsilon(r) = 1 0 : 2 to achieve high radiation efficiency with small physical size. In order to increase the robustness against misalignment, a circularly polarized antenna is used at the external receiver unit, reducing the signal power variation under angular misalignment. For the transmitting antenna a miniaturized prototype with an integrated pulse generator was designed on a round shaped PCB with a diameter of only 1 4 mm. Measurements through porcine skin in the frequency domain show an attenuation of less than 3 0 dB in the intended frequency band between 6 and 8.5 GHz. Additional evaluations in the time domain prove possible pulse repetition rates of up to 100 MHz at a transmission distance of 1.5 cm. |
