Digest (1989), pp. 458-462 vol.1.</i><br /><br />It is demonstrated that a thick patch with an annular gap matching capacitor is an optimum element from a practical design point of view, giving wide bandwidth operation, although at the expense of poor cross polarization. Feed inductance and radiation pattern effects are examined and a new patch equivalent circuit is developed that gives significantly improved results over the existing lumped element model Microstrip patch antennas on thick substrates PS Hall JS Dahele PM Haskins doi:10.1109/APS.1989.134719 Antennas and Propagation Society International Symposium, 1989.

Radiation from active circuits is analysed using equivalent source method and results presented for isolated transistors and transistor amplifiers. An active patch element with application to phased arrays is then described Microstrip active antennas PS Hall PM Haskins JS Dahele Phased Arrays, IEE Colloquium on (1991), pp. 9/1-9/4. 2008-05-09T23:43:12-00:00 1991 Phased Arrays, IEE Colloquium on 9/1 9/4 active antenna microstrip
