UWB Electric and Magnetic Monopole Antennas

Abstract

Abstract-This paper summarizes our recent advances in antenna designs for ultra wideband (UWB) applications. Two types of monopoles are studied and developed in our research group. The first type belongs to the electric monopole with a circular disc fed by three different feeding structures. The second type is the magnetic monopole with an elliptical slot. The performances of these two types of antennas are evaluated in both frequency and time domains. The important design parameters for achieving optimal operations are also analyzed. It is shown that both electric and magnetic monopoles can provide ultra wide bandwidth with nearly omni-directional radiation patterns over the entire frequency band. In addition, the impulse responses of the selected antennas are shown to correspond well to the frequency domain characteristics.

A new patch antenna for ultra wide band communication applications

“…Ultra-wideband is a technology used to increase the bandwidth, this technology is recognized by the Federal Communication Committee (FCC), it has a bandwidth of up to 7.5GHz, from 3.1GHz to 10.6GHz [4][5][6][7][8][9]. This technology sends the data in form of a train of pulses instead of using carrier signal to transmit the data, the width of these pulses is very narrow estimated few nanoseconds, so it has a wide band spectrum [10,11]. The UWB system has advantages such as the power consumption is low because it does not use carrier signal, high data rate due to large bandwidth and low interference [12,13].…”
