A novel wideband rectangular dielectric resonator antenna (RDRA) is proposed in this paper. An equivalent air-dielectric DRs blocs are introduced inside the resonator to enhance the structure's bandwidth. The hybrid structure is excited by a simple …
This letter presents a reconfigurable antenna for mobile terminals with extended band coverage obtained by using a digitally tunable capacitor (DTC). The antenna structure is matched permanently over high frequency bands including DCS/PCS, UMTS, LTE …
In this paper, an approach for the design of antennas suitable for vehicular applications is presented. The resulting solutions are light, low-profile and they exhibit good impedance match and omnidirectional radiation pattern over the band of …
This paper presents a compact low-profile surface wave antenna for UMTS applications. It shows good impedance match and dipole-like omnidirectional radiation pattern over the band of interest. Numerical and experimental results are reported to …
In this letter, a spline-shaped ultrawideband (UWB) antenna enabling simultaneous operability over multiple mobile wireless standards-namely the DCS, PCS, UMTS, and ISM bands-is proposed. The antenna is expected to exhibit a good impedance matching …
In this letter, the prototype of a planar antenna working in three different frequency bands and suitable to be integrated in multimode wireless devices is described. The antenna is fed by a single RF port without any matching circuit, and it …
