A vehicle antenna apparatus, including directional antenna elements arranged to be mountable in a distributed array around and pointing away from a vehicle, a powering means configured to power the directional antenna elements in phase with each other, and a method of use and manufacture of the same. The antenna apparatus further includes an omnidirectional antenna arranged to be mountable with the vehicle, with the powering means being further configured to power the omnidirectional antenna in-phase with the directional antenna elements. This provides a combined radiative performance radiating away from the vehicle suitable for communications applications.

Vehicle antenna apparatus, method of use and manufacture

A dual polarised omnidirectional antenna apparatus () capable of operating in transmit and receive, comprising at least two dual polarised directional antennas () configured to be mountable in a substantially equi-spaced distributed array around and pointing away from a platform, wherein the antenna apparatus () is configured such that, when operated in transmit, the dual polarised directional antennas operate in phase with each other to deliver a combined omnidirectional, dual polarised, performance. This increases operational bandwidth and mitigates interference effects in communications applications.
