Variation of permittivity in radial direction in concentric half-split cylindrical dielectric resonator antenna for wideband application

摘要: Design and development of wideband concentric half-split cylindrical dielectric resonator antenna (CDRA) using permittivity variation in radial direction has been proposed this article. The homogeneous, two-layer three-layer CDRAs have discussed separately. effect parameters such as layer arrangement, geometrical parameters, probe length are investigated. To validate the results, CDRA fabricated commercially available microwave laminates. In each case, input reflection coefficient, radiation pattern, gain simulated measured. Good agreements between measured results obtained. © 2014 Wiley Periodicals, Inc. Int J RF Microwave CAE 25:321–329, 2015.
