The authors report the design of an ultra‐wideband (UWB), dual‐polarised, tightly coupled dipole array (TCDA) with an integrated balun for wide‐angle scanning. A dual‐pol dipole design enables massive bandwidth, large scanning volume, and hig

Novel methods of improving directivity and decreasing sidelobe radiation via the addition of an elliptical pseudoelement and irregularly spaced notches in the tapered slot antenna are presented in this paper. This antenna has been shown to be functio

We present a wideband tightly coupled dipole array (TCDA) with integrated balun and a novel superstrate consisting of printed frequency selective surface (FSS) for wide angle scanning. Although previous TCDAs have had decent scanning performance up t

A wideband high-isolation two-port antenna of low profile and omnidirectional pattern is presented. This two-port system consists of a collocated antenna pair with a cone antenna in the middle and a ring radiator around the cone, both placed over a r

We present a collocated pair of antennas, operating from 700 to 2700 MHz. The antenna structure consists of two wideband dipole elements placed at height 0.093 λlow above a 0.47 λlow×0.54 λlow ground plane. The dipoles achieve an isolation of abo

A novel way to reconfigure the bandwidth (BW) of a tightly-coupled array (TCA) is presented. This is done using a reconfigurable frequency selective surface (FSS) on top of the array. The reconfigurable FSS demonstrates a tunable narrow passband, emu

A mechanism for tunable band rejection in the reconfigurable balun of an ultra-wideband (UWB) tightly-coupled array (TCA) is presented. A variable capacitor increases and controls the effective length of the balun's short stub, shorting out the dipol

We present a wideband Tightly Coupled Dipole Array (TCDA) with integrated balun and novel parasitic superstrate capable of wide angle scanning. Although previous TCDAs have been shown to have good scanning performances, use of dielectric superstrates
