A novel design for the microstrip leaky-mode antenna array with high-efficiency

Abstract

A novel design of a closely coupled microstrip leaky-mode antenna array is proposed, built, and tested, showing the gain of 19.35 dB, directivity of 19.8 dB, and overall radiation efficiency of 83%. Detailed analyses and array design are presented for prototyping an eight-element antenna array. Excellent agreement between the theoretical and measured results is obtained.
