An apparatus including a dipole antenna, configured for operation with a first polarization, the dipole antenna including a feed; and a pair of conductive elements fed by the feed, wherein the pair of conductive elements are grounded, and extend in parallel on opposing sides of the feed and then diverge.

Dipole antenna

According to an aspect, there is provided a passive antenna module for an active-passive antenna system. The passive antenna module includes a chassis for detachably mounting onto an active antenna module. The chassis includes an opening or a cavity for extending at least partially over the active antenna module when the chassis is mounted onto the active antenna module. The passive antenna module includes a ground plane layer arranged within or over said opening or cavity and fixed to the chassis. The ground plane layer includes a metallic or metallized grid. The passive antenna module includes a first antenna array including one or more first antenna elements arranged, in part, over said chassis and adjacent to said opening or cavity and, in part, over said opening or cavity. The chassis and the ground plane layer are adapted to act as ground planes for the first antenna array.

Compact modular active-passive antenna systems with minimized antenna blockage

An antenna system including a first antenna, a second antenna and a third antenna. The antenna system includes a feed for feeding a first common signal to radiator elements of one of the second antenna or third, with a first phase difference between the radiator elements configured for a first polarization and the radiator elements being configured for a second polarization, to create a virtual polarization, wherein the virtual polarization is aligned with one of the first polarization or the second polarization in a first frequency band.
