High gain W-shaped microstrip patch antenna
IEICE Electronics Express, 2010 A high gain W-shaped microstrip patch antenna is proposed and experimentally investigated. The patch antenna employs a new inverted W-shaped patch structure with meander probe feed technique. A prototype of the proposed antenna is fabricated and tested for validation.

Optimal rate allocation for shape-gain Gaussian quantizers [PDF]
Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252), 2002 We derive the optimal rate allocation of the shape and gain components of a certain shape-gain quantizer for a Gaussian source. The rate allocation results are of particular interest because the shape-gain quantizer addressed in this paper is the best vector quantizer known for the memoryless Gaussian source at rates of three or higher.
