Abstract
A parallel feed network antenna and a method for making a parallel feed network antenna having improved consistency in antenna pattern and improved reliability and which is easier and cheaper to manufacture is disclosed. In one embodiment of the present invention, a housing containing raised surfaces defining a channel is formed using plastic injection molding techniques. A layer of conductive material such as copper is selectively deposited over the surface of the housing so as to cover the channels. The upper surface of the housing is then removed until the conductive material which overlies the raised surfaces adjoining the channel is removed so as to form a microstrip. The patch antenna are then attached to the housing and electrically coupled to the microstrip to complete the antenna.
