The paper presents a method of antenna array pattern shaping, i.e. beamforming, for Impulse Radio Ultra-Wideband (IR-UWB) correlation beamformers. The method is based on Second Cone Programming (SOCP) and allows for several parameters of shaped pattern to be simultaneously optimized; it allows for arbitrary antenna array geometry as well as for arbitrary UWB frequency-dependent radiation pattern to...
Brain-Machine-Interface (BMI) will transfer the neural activities of brain to machine for potential actions. Antenna for Brain-Machine-Interface needs to be very small, due to limited available space in human head. Ultra Wideband (UWB) technology with their low cost, low power consumption, high data rate and small form factor of antenna is one of the strong candidate for medical implanted devices...
Visualization of stomach and small intestine, nowadays can be done with wireless capsule endoscopy. However, the limitation of bandwidth at low frequencies such as Industrial, Scientific and Medical (ISM) band and Medical Implant Communication Service (MICS) band do not provide high resolution images. One of the possible frequency band to have clear images from digestive organs is the use of Ultra...
