In this paper, an ultra-wideband dielectric resonator antenna is proposed for wireless communication device applications. The antenna can provide the monopole-like radiation pattern and the mushroom-like radiation pattern in the operation band from 3.9 to 12.2 GHz (VSWR≤2) through the in-phase feed and the out-phase feed of two input ports, respectively.
In this paper the analysis and design of compact CPW-fed slot antenna that operates in the IEEE 802.11a frequency band from 5.15 GHz to 5.35 GHz for wireless applications through a single grounded coplanar waveguide port for achieving sectorized radiation pattern is presented. The antenna is designed on a RT/duroid 5880 substrate with a permittivity 2.22 and with the size of 18.8 mm times 12.3 mm...
In this paper, design of a quarter wave transformer-fed circular patch antenna is presented. The maximum size of proposed antenna is 25.4 mm by 25.4 mm. The substrate material used for this antenna has thickness of substrate 0.762 mm and relative permittivity epsivr 3.2. The design frequency of the antenna is 10 GHz. By selecting optimum parameters of proposed antenna, the measured return loss of...
In this paper design and fabrication of microstrip line fed aperture coupled patch antenna is presented at 10 GHz using 0.762 mm and .508 mm thick (epsivr=3.2) substrates. The maximum size of proposed antenna is 35.4 mm by 35.4 mm. The design is optimized by means of parameter-variation studies that have been performed using a 3D electromagnetic simulator. A novel bandwidth enhancing network is described,...
