Wideband VHF self complementary antenna

The batch product is very difficult to make economically viable production. In Aviation industries, faces such issues. The common and cheaper solution with identical product repeatability for the product is good solution. The solution proposed here is a design of a product which can be shared in different projects. This, in turn, also provides leverage for small batch production cost, as same item can be used at multiple places and hence provides quantity benefit to manufacturer. Also product can be produced easily and repeatedly with the same specifications and same quality including accepted tolerances. The solution provides reusability and sharability of a product for different purposes or projects. This work for broadband antenna in the specialized area of navigation aids and design a self complementary antenna from about 75 MHz to 400 MHz. It is developed based on strip line technology which covers the band of direction finder (VHF & UHF). Also can be used for the Instrument Landing System (equipments like Marker beacon, Localiser and glidepath).
