A compact multiband monopole antenna with a defected ground plane
(2008)A compact multiband antenna is proposed that consists of a printed circular disc monopole antenna with an L-shaped slot cut out of the ground, forming a defected ground plane. Analysis of the current distribution on the ...

Direct quadrature phase shift keying modulation using compact wideband six-port networks
(2012)In this study, the operation of a compact six-port network operating as a quadrature phase shift keying (QPSK) modulator with a wide operational bandwidth is presented. The modulation has been accomplished using two types ...

A Directivity-Band-Dependent Triple-Band and Wideband Dual-Polarized Monopole Antenna Loaded with a Via-Free CRLH Unit Cell
(2015)A printed triple-band and wideband dual-polarized meander-line monopole antenna with a single CRLH metamaterial loading is presented. The metamaterial loading improves the impedance matching and causes the proposed antenna ...
