  • Broadband elliptical dielectric resonator antenna 
    Bijumon, P V; Sreedevi K Menon; Suma, M N; Lethakumary, B; Sebastian, M T; Mohanan, P (Wiley, 2006)
    A broadband low-loss elliptical dielectric resonator antenna (DRA) excited by using the microstrip-line technique is proposed. The effect of geometrical modifications of the microstrip feed line on the gain, bandwidth, and ...

  • A compact hybrid CPW fed planar monopole/dielectric resonator antenna 
    Suma, M N; Bijumon, P V; Sebastian, M T; Mohanan, P (Elsevier, 2007)
    Design of hybrid antenna consisting of a coplanar waveguide (CPW) fed printed monopole and cylindrical dielectric resonator is presented in this paper. A CPW fed printed monopole acts as an effective radiator and excites ...
  • FDTD analysis of rectangular dielectric resonator antenna 
    Mohanan, P; Mridula, S; BinuPaul; Suma, M N; Bijumon, P V; Sebastian, M T (Elsevier, 2007)
    The paper presents basics of electromagnetic theory and dielectric resonator antennas, fundamental concepts of FDTD and some significant results of the FDTD analysis of rectangular dielectric resonator antennas (RDRA)
  • Low dielectric loss PTFE/CeO(2) ceramic composites for microwave substrate applications 
    Anjana, P S; Sebastian, M T; Suma, M N; Mohanan, P (Wiley, 2008)
    Cerium oxide (CeO(2)) filled polytetrafluoroethylene (PTFE) composites prepared by powder processing technique for microwave substrate application is presented in this paper. The PTFE is used as the matrix and the dispersion ...
  • Rectangular dielectric resonator antenna on a conductor-backed co-planar waveguide 
    Suma, M N; Sreedevi K Menon; Bijumon, P V; Sebastian, M T; Mohanan, P (John Wiley & Sons, 2005)
    In this paper, we present an effective excitation of a rectangular dielectric resonator antenna (DRA) with a conductor-backed co-planar waveguide (CB-CPW). The radiation and resonance characteristics are found to vary, ...
