An Improved Design of Planar Elliptical Dipole Antenna for UWB Applications

Ultra-Wideband Antenna Design for GPR Applications: A Review

“…In [50], an elliptical-shaped structure is introduced into each of the dipole's arm as shown in Fig. 6.…”

A Novel Rectangular Ring Planar Monopole Antennas for Ultra-Wideband Applications

“…Only designs in [9,16], and [21] have smaller areas than the proposed antenna, but with larger volumes, lower gains, and smaller bandwidths.

“…A microstrip UWB antenna is presented in [8] with size of 34 mm×36 mm×1.6 mm, operated only from 4.6 GHz to 9.6 GHz. The detailed comparison with other antennas presented in [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] is given in Table 1. The proposed rectangular ring ultra-wideband planar monopole antenna has a size of 28 mm× 26 mm×1.525 mm with impedance bandwidth of 124.16% and gain varying between 1.89 dBi to 5.2 dBi.…”

CPW-Fed Uwb Compact Antenna for Multiband Applications

“…Presently, the focus has shifted to antennas that work in the ultra-wide band (UWB) range used for short range and high data rate communications. Recently, small size antennas have been designed for UWB systems to cover the interval 3.1-10.6 GHz [12][13][14]. However, most of the work presented so far use separate antennas for lower bands and UWB applications.…”
