Millimeter-wave band-pass filters using spherical dielectric resonators are presented. The dielectric spheres are sandwiched between metal plates and are excited by a simple microstrip line structure on a thin-film circuit board. As such, these filte

A new lens antenna for wide-angle beam-steering application is presented. The 2-D lens permittivity profile according to Luneburg is modified using transformation optics to obtain a planar focal surface, allowing for a simple cost-effective planar fe

This study presents the design and characterisation of a modified planar Luneburg lens antenna operating at 30 GHz. A parallel plate lens structure with varying separation between the metal plates realises the required variation of phase velocity of

This letter demonstrates a novel integration approach to design high gain chip-fed antennas in V -band and W -band. An on-chip spherical dielectric resonator is integrated with a resonant cavity antenna, which resulted in high radiation efficiency an

This paper demonstrates the resonant cavity antenna's (RCA) integration capability with the millimeter-wave (mm-wave) transceiver chips. A broadband RCA fed by a probe-fed microstrip patch, which is readily integrated with transceiver chips, is desig

A new concept for a figure of merit for beam-steering antennas is proposed. The new figure of merit quantifies how efficiently an antenna with beam-steering capability can make use of its aperture size to radiate beams into a wide geometrical sector.
