Abstract
A VHF/UHF communications blade type antenna additionally having microwave nding system (MLS) antenna elements mounted thereon and having the microwave feed components integral therewith to provide a composite structure adapted to function both as a communications and as a navigation antenna. The antenna is particularly adapted for use with aircraft which is to be retrofitted to include MLS capability.
Claims11
An antenna configuration for aircraft having a VHF/UHF antenna means enclosed within a dielectric radome which has an airfoil configuration attached to a base, the VHF/UHF antenna means being a blade type comprising a pair of like planar radiator elements located on opposite faces of a planar dielectric member, said base being adapted for mounting on the aircraft and acting as a ground plane, and having a VHF/UHF antenna and communications apparatus within the aircraft, the improvement comprising:
- microwave antenna means for the Microwave Landing System comprising a pair of like microwave antenna elements located within said radome outside opposite faces of said dielectric member, a microwave signal feed point in said base, microwave feed means disposed interiorly of said radome coupling the microwave signal feed point to the microwave antenna elements, with the microwave feed means including phasing means to feed the microwave antenna elements in a desired phase relation, the phase relation and the location of the microwave antenna elements being that which produces a desired omnidirectional pattern as required for the Microwave Landing System.
