This article proposed a wideband circularised polarised (CP) Cylindrical Dielectric resonator antenna (CDRA) for Extended C and partially X band applications. A tilted aperture and microstrip feed line are used for resonating the proposed antenna between frequency band 5.93 GHz–10.90 GHz with 59.06% (4970 MHz) bandwidth. The proposed antenna also creates two circular polarization (CP) waves between the frequency band 6.49 GHz–6.74 GHz and 8.07 GHz–8.41 GHz with 3.77% (250 MHz) and 4.12% (340 MHz) 3 dB axial ratio bandwidth (ARBW), respectively.

摘要

This article proposed a wideband circularised polarised (CP) Cylindrical Dielectric resonator antenna (CDRA) for Extended C and partially X band applications. A tilted aperture and microstrip feed line are used for resonating the proposed antenna between frequency band 5.93 GHz–10.90 GHz with 59.06% (4970 MHz) bandwidth. The proposed antenna also creates two circular polarization (CP) waves between the frequency band 6.49 GHz–6.74 GHz and 8.07 GHz–8.41 GHz with 3.77% (250 MHz) and 4.12% (340 MHz) 3 dB axial ratio bandwidth (ARBW), respectively.
