A novel tapered slot PCS antenna array and model

An antenna array comprising multiple tapered slot radiators and its microstrip, feed network has the capability to be etched on a single piece of thin dielectric circuit board resulting in the relatively inexpensive mass production of a highly consistent product. A modification to the conventional tapered slot aperture that results in improved SWR performance is presented. An accurate radiation pattern prediction of arrays of tapered slot antennas is also presented. Measured results of actual hardware indicate good correlation with the predicted model in both the main beam and back lobe regions.
