微带贴片天线通常具有包含不需要的副瓣或由表面波引起的局部极小值的辐射模式，特别是在高介电常数衬底上制造时。本文表明，去除贴片下的衬底可以大大改善图案。该技术的一种变体，与单片制造兼容，被应用于GaAs贴片的制造，并显示出类似的模式改进。>
Microstrip patch antennas typically have radiation patterns containing unwanted sidelobes or local minima caused by surface waves, especially when fabricated on high dielectric-constant substrates. The paper shows that removal of the substrate beneath the patch can greatly improve the pattern. A variation of this technique, compatible with monolithic fabrication, is applied to fabrication of a patch on GaAs and shows similar pattern improvement. >
