An ultrawideband antenna based on a short dielectric dipole has been developed to sound dielectric layered media and to search objects including those hidden behind a dielectric barrier.
Abstract: in this article, we present a new design concept for a multifunctional antenna providing single/dual frequency-notched ultrawideband (uwb) capability and its complementary multiple narrow-band functionality from a printed coplanar waveguide (cpw)-fed annular-ring monopole antenna (arma). We achieved the proposed multiple antenna configurations by loading square split-ring resonator (srr) pairs of different dimensions beneath the substrate and above the superstrate, along with.
Abstract: we have designed, simulated, fabricated, and tested an ultra-wideband (uwb) multifunctional communication and radar system utilizing a single shared transmitting antenna aperture. Two surface acoustic wave bandpass chirp filters were used to modulate the radar and communications pulses, generating linear frequency modulation waveforms with opposite slope factors.
