“…Several UWB planar antennas have been designed with various shapes, slot [3][4][5] and monopole [6][7][8][9]) and different types of excitation, including microstrip and coplanar wave-guide CPW. They have been proposed to operate within the UWB spectrum band between 3.1 GHz and 10.6 GHz.…”

“…Therefore, several techniques have been proposed to broaden the impedance bandwidth of small antennas and to optimize their characteristics. These techniques include several approaches, such as coplanar waveguide (CPW) fed slot antennas using a tuning stub with rectangular shape [3], circular shape [4], fork-like shape [5] and CPW-fed planar broad-band monopole antennas, having rectangular, circular, elliptical, and trapezoidal forms [6][7][8][9].…”

Abstract-In this paper, an ultra-wideband (UWB) patch antenna integrated with a dielectric resonator is proposed for cognitive radio applications. The patch antenna is fed by a coplanar waveguide (CPW) line, and it consists of a rectangular monopole having an elliptical base, and operates from 2.44 to 12 GHz. This UWB antenna is intended to collect the information. Moreover, the proposed structure integrates a narrow-band rectangular dielectric resonator antenna (RDRA) for operation, with very good isolation between the two ports (transmission coefficient S 21 less than −20 dB). The RDRA provides a bandwidth from 5.23 GHz to 6.11 GHz. The electromagnetic analysis is carried out using tow commercial software tools. Furthermore, to validate the proposed concept, experimental measurements are also performed.

“…This antenna achieves an impedance bandwidth ratio of 3.7:1 (2.95~11 GHz). Gopikrishna et al [50] introduced a semi-elliptic slot antenna. The antenna features a CPW signal strip terminated with a semi-elliptic stub and a modified ground plane to achieve a wide bandwidth ratio of 7:1 (2.85~20 GHz).…”

“…For example, the trapezoid slot structures with various exciting stubs were employed to design printed slot antennas [12][13][14], resulting in extremely large impedance bandwidths. The semi-elliptic slot ground plane with a semi-ellipse patch was also proposed for wideband operation [15]. Additionally, slot antennas with notchedband in [16] were proposed using either narrow slits or strips for only single frequency rejection.…”
