High-gain printed monopole arrays with low-complexity corporate-feed network

Printed monopole antennas fed by microstrip lines can provide a wide bandwidth and can be employed as terminal antennas in RF circuits. In the same perspective, the authors propose a novel planar array in which N + 1 parasitic monopoles, properly placed in a linear array where only N directly-fed monopoles are used, allow a broadside radiation and a gain value close to that of a standard printed a...
