In this paper, a wideband electronic beamforming concept applicable for UWB short pulse systems is derived and experimentally demonstrated. In particular, a Finite Impulse Response (FIR)-filter based beamforming network is configured such that an antenna array yields a desired radiation pattern within a predefined frequency range. An experimental verification of a wideband transmission system i...

Wideband channel measurements have been used extensively to determine path loss and time dispersion characteristics of radio channels (e.g., [1], [2], [7]). The principles used to temporally resolve individual received signal components for wideband propagation measurements can be applied to antenna pattern measurements to achieve more accurate results. Multipath, a propagation phenomenon which...

A compact rectangular printed antenna with dual band-notches is proposed for ultra-wideband (UWB) applications. The dual band-notch characteristics have been realized by etching one C-shaped parasitic element and rectangular split ring resonator above the ground plane. The proposed antenna can achieves a wide bandwidth from 2.9-11 GHz with the dual notched bands centred at 5.25 GHz and 5.8 GHz....

Abstract—In this paper, we use the concept of stub loadings of planar microstrip antennas to convert a single band antenna into a dual-band antenna used for WLAN. We load a planar triangular monopole (PTM) antenna by combline stubs attached to the edges of patch in order to obtain a second resonance frequency. The simple PTM antenna is first designed to produce the lower resonance frequency and...
