Radio antenna aspiration.
W e have had much experience with foreign body aspiration, but children still continue to surprise us with strange aspirated materials. A telescopic radio antenna was observed on the chest roentgeno-gram of a 2-year-old girl (Fig 1A and 1B), located just below the vocal cords and extending to the main carina. It was removed without any complications by rigid bronchoscopy (Fig 1C).
متن کاملAdvanced Radio Resource Management for Multi Antenna Packet Radio Systems
In this paper, we propose fairness-oriented packet scheduling (PS) schemes with power-efficient control mechanism for future packet radio systems. In general, the radio resource management functionality plays an important role in new OFDMA based networks. The control of the network resource division among the users is performed by packet scheduling functionality based on maximizing cell coverag...
متن کاملWideband Antenna Characteristics for UWB Radio Systems
Ultra Wideband (UWB) Radio Systems require small and efficient antennas with a suitable transient radiation behavior like small bi-conical and mono-cone antennas and their planar relatives. For some applications like ceiling mounted access points conformal antenna solutions like spiral antennas are of special interest. INTRODUCTION Spectrum is presently one of the most valuable goods worldwide ...
متن کاملSmart antenna for wi-max radio system
In simple words, smart antenna is such that it can sense its environment and can adjust its gain in different directions accordingly. They provide a smart solution to the problem of communication traffic overload i.e. they increase the traffic capacity. They also improve the QOS. RF spectrum is a limited resource and is becoming crowded day by day due to the advent of new technologies. The sour...
متن کاملDesign and Fdtd Modeling of Millimeter Wave Antenna for Wireless Sensor Networks
This paper presents the design and finite difference time domain (FDTD) modeling of millimeter wave aperture coupled microstrip antenna that can be realized as a on chip antenna in wireless sensor nodes. At millimeter wave frequency, antenna form factor is very low and hence integration of this antenna with the transceiver components as a single system on-chip, minimizes power consumption and s...
