请问：PIFA里的shorting strip 与 shorted patch指什么？

原文：A compact wideband modified planar inverted
antenna (PIFA) with two shorting strips [/COLOR]for 2.4/5.2-GHz wireless local area network (WLAN) operations is presented. As a starting
point, two-branch strip lines derived from the dipole antenna
structure are used to achieve the desired resonant frequency. One
of them is connected to two shorting strips with the different length
and width, and those strips generate additional resonant modes.
A wideband characteristic can be optimized by tuning the parts
of two shorted patches [/COLOR]and size of each strip line segment.
shorted meander strip[/COLOR]
radiating strip[/COLOR]
蓝色的部分，我都不明白，真诚希望各位高手指点一下， 谢谢！
