“…Moreover, the remarkable broad and ultra wideband (UWB) features offered by DRAs introduce them as potential candidates for UWB systems [2][3]. Using hybrid configurations, several monopole-DRAs were studied, which were constructed by a vertical monopole antenna loaded with a ring-shaped dielectric resonator (DR) around in the horizontal plane [2].…”

An ultra-wideband (UWB) rectangular dielectric resonator antenna (DRA) integrated with a narrow-band (NB) DRA is presented. The proposed antenna consists of a UWB DRA excited by a planar monopole and a DRA excited by a slot which displays NB characteristic. The UWB and NB antenna provides a 2:1 voltage standing wave ratio (VSWR) bandwidth for 2.5 -11 GHz and 5.1 -5.5 GHz, respectively, with the same polarization and a reasonable isolation (better than -10 dB ) between the two ports. Moreover, the NB antenna can operate in 6.8 -7.3 GHz or 3.75 -3.88 GHz by little modification. This is a promising candidate for applications of cognitive radio, where a UWB antenna is for spectrum sensing and a NB antenna for communication operation. To improve the isolation between the two ports, several arrangements are investigated.

“…They can maintain high radiation efficiency, even at millimeter-wave frequencies due to low surface wave losses and minimal conductor losses. Moreover, the remarkable broad and ultra wideband (UWB) features offered by DRAs make them as potential candidates for UWB systems [2][3][4][5][6][7][8][9]. The intensive investigations on UWB DRAs have been pursued and published.…”

“…The intensive investigations on UWB DRAs have been pursued and published. Using hybrid configurations, several monopole-DRAs have been studied, which are constructed by a vertical monopole antenna loaded with a ring-shaped dielectric resonator (DR) around in the horizontal plane [4][5][6][7][8]. Recently, a combination of broadband planar monopole and a rectangular DRA has been reported, which has a bandwidth from 3.06 to 10.6 GHz [9].…”

Abstract-An ultra-wideband (UWB) planar monopole antenna integrated with a narrow-band (NB) cylindrical dielectric resonator antenna (DRA) is presented. The proposed antenna consists of a UWB monopole excited by a coplanar waveguide (CPW) transmission line, acting as a ground for a DRA excited by a slot. The mode HEM 11δ is excited in the NB DRA. To validate the concept of integration, an antenna is fabricated and measured. The measured results demonstrate that the UWB antenna provides a 2 : 1 voltage standing wave ratio (VSWR) bandwidth for 3.05-11 GHz, integrated with a dual-band NB antenna. Moreover, the two ports have the same polarization and a reasonable isolation (less than −10 dB) between each other. This is a promising candidate for applications in cognitive radio, where the UWB antenna can be used for spectrum sensing and the NB antenna for communication operation.

“…The monopole antenna [6] is a widely employed planar antenna but suffers a major flaw of narrow bandwidth due to reducing antenna size. Many attempts have been made to extend the antenna bandwidth, such as adopting fractal geometries [7], adding parasitic elements [8], and using additional substrate [9]. In this proposed antenna, we use a simple inverted-U-shaped driven element, a low-frequency meander path, and a matching stub with a truncated slit to achieve the application requirements.…”

Abstract-This paper proposes a novel multi-band monopole antenna for PDA phone. A simple inverted-U-shaped driven element operates frequency bands centered at 1710 and 2350 MHz, which achieve a bandwidth based on 6-dB return loss from 1550 to 2490 MHz sufficient for DCS, PCS, UMTS, and WLAN applications. A low frequency meander path and an impedance matching stub with a truncated slit located at ground plane operates frequency band centered at 910 MHz. The bandwidth from 868 to 995 MHz covers the GSM 900 application band. The design procedures and both simulated and measured results are presented and discussed in this paper.
