    A novel design of compact planar inverted F-antenna (PIFA) is proposed for dual band resonant frequencies. The antenna is designed and fabricated on FR4 cheap substrates with dielectric constants epsivr=4.7, respectively. Over 95% reduction in the antenna size is achieved from conventional lambda0/4 rectangular PIFA resonating at same frequencies. This is done by implementing... View full abstract»

    Fast and efficient vectorial modal analysis of a 2-D magneto-dielectric grating structure is presented. This modal analysis is combined with the generalized scattering matrix to obtain the transmission and reflection coefficients of multilayered 2-D magneto-dielectric grating slabs. The accuracy of this technique is verified with previously published results obtained by using method of moment View full abstract»

    Two patch array antennas have been proposed for detection of buried land mines using the mutual coupling effect. Mutual coupling among the edges of a patch or among the edges or nearby patches can influence the performance of microstrip antennas and arrays. The finite-difference time-domain method (FDTD) is used. The patch array antennas (sensor) have been simulated to detect various types of targ... View full abstract»

    Transverse coupling between single mode fiber and single mode planar waveguide is analyzed for the first time-to the authors' knowledge-by an improved coupled mode theory (ICMT). The coupling is established via the evanescent part of the modal field propagating in the fiber which penetrates the slab waveguide. The main parameters that characterize the coupling process are calculated. A comparison ... View full abstract»

    This paper studies the performance of existing receive antenna selection algorithms in spatially correlated fading MIMO channels. The antenna subset is selected based on maximizing the channel capacity. First the most recently proposed algorithms, which are dedicated to i.i.d channel, are revisited and investigated. Then, we apply these algorithms to the case of correlated fading channel. The perf... View full abstract»
