MOTEVASSELIAN, A. and WHITTOW, W.G., 2015. Patch size reduction of rectangular microstrip antennas by means of a cuboid ridge. IET Microwaves, Antennas & Propagation, 9(15), pp. 1727-1732.
An effective approach to reduce the patch size in rectangular patch microstrip antennas is presented. The proposed approach is based on inductively loading the patch using a cuboid ridge. A theoretical
background of the approach using the transmission line model has been provided. A prototype of the proposed antenna is fabricated and measured. The results, advantages and limitations of the proposed
approach are presented and discussed.
