Double-port slotted-antenna with multiple miniaturized radiators for wideband wireless communication systems and portable devices
(Electromagnetics Academy, 2019)
info:eu-repo/semantics/article,
Proof-of-concept is presented of a novel slot antenna structure with two excitation ports. Although this antenna provides a wide impedance bandwidth, its peak gain and optimum radiation efficiency are observed at its ...
Wideband printed monopole antenna for application in wireless communication systems
(IET, 2018)
info:eu-repo/semantics/article,
Empirical results of an electrically small printed monopole antenna are described with a fractional bandwidth of 185% (115 MHz to 2.90 GHz) for return-loss better than 10 dB, peak gain and radiation efficiency at 1.45 GHz ...
Antenna mutual coupling suppression over wideband using embedded periphery slot for antenna arrays
(MDPI, 2018)
info:eu-repo/semantics/article,
This paper presents a new approach to suppress interference between neighbouring radiating elements resulting from surface wave currents. The proposed technique will enable the realization of low-profile implementation of ...
Meta-surface wall suppression of mutual coupling between microstrip patch antenna arrays for THz-band applications
(EMW Publishing, 2018)
info:eu-repo/semantics/article,
This paper presents a novel 2D meta-surface wall to increase the isolation between microstrip patch radiators in an antenna array that is operating in the teraherz (THz) band of 139-141 GHz for applications including ...
Surface wave reduction in antenna arrays using metasurface inclusion for MIMO and SAR systems
(Advancing Earth and Space Science, 2019)
info:eu-repo/semantics/article,
An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for multiple-input multiple-output (MIMO) and synthetic aperture radar (SAR) ...
High-isolation leaky-wave array antenna based on CRLH-metamaterial implemented on SIW with ±30° frequency beam-scanning capability at millimetre-waves
