A wideband circularly polarized (CP) slot antenna with L-slot and L-shaped feed is designed. Wideband CP is obtained by truncating a corner of the antenna element, and by exciting the L-slot with asymmetric L-shaped feed line. This geometry introduces orthogonal components with quadrature phase difference to excite circularly polarized wave. The antenna attains an overlapped bandwidth (axial ratio...
Multiple input, multiple output (MIMO) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize the errors and to optimize the data speed. MIMO-based antennas are of interest in relation to communication such as digital TV,...
0.95MgTiO3-0.05CaTiO3 high-permittivity ceramic have been applied in the fabrication of dielectric resonator antenna. The permittivity and quality factor of 0.95MgTiO3-0.05CaTiO3 have been characterized. The dielectric resonator antenna is fed with a mico-strip line. Fabricated dielectric resonator antenna was measured by an Agilent N5230A network analyzer. The measurement result of the antenna composed...
