Bandwidth Enhancement of Compact Monopole Antennas for Application in UWB Communication System
In this paper a microstrip transmission line fed compact monopole antenna for the wide-band (2. 5 GHz 11 GHz) communication system is designed and its performance is verified. In particular, we have simulated four types of wideband monopole antennas: rectangular, modified rectangular, circular and modified circular disk monopole antennas. Simple rectangular microstrip lines are used for feeding...
متن کاملCreating Band-Notched Characteristics for Compact UWB Monopole Antennas
In 2002, the FCC in the US authorized the unlicensed use of the ultrawideband (UWB) frequency spectrum for commercial applications in the range from 3.1 to 10.6 GHz with an emission limit of -41.3 dBm/MHz which is near to the thermal noise floor [1]. UWB communication systems operating in such a wide frequency band and low power emission level could easily be interfered by the existing nearby c...
متن کاملBand-Rejected UWB Monopole Antenna with Bandwidth Enhancement
─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...
متن کاملCompact UWB Monopole for Multilayer Applications
A novel compact, dual layer UWB monopole antenna is presented. This low profile ultrawideband antenna is fed by a 50 Ω shielded strip-line with an array of metal vias making the conducting walls. A printed disc monopole with a circular cut is the radiating element. The dual layer, shielded strip line feed allows for integration in multilayer technologies. The ultra-wideband, monopole characteri...
متن کاملUWB Electric and Magnetic Monopole Antennas
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...
