Gain Enhancement of Low-Profile, Electrically Small Capacitive Feed Antennas Using Stacked Meander Lines

Figure 4

Proposed stacked structures with two layers.

(a) CFMA stacked a meander line in the same direction (2L-CFMA1)

(b) CFMA stacked a meander line in the opposite direction (2L-CFMA2)

(c) Expanded figure of 2L-CFMA1

(d) Expanded figure of 2L-CFMA2

(e) Dismantled structure for 2L-CFMA1

(f) Dismantled structure for 2L-CFMA2
