Design Variations on Planar Differential Antenna with Potential for Multiple, Wide, and Narrow Band Coverage

Figure 8

Simulated and measured gain patterns for three different frequencies (2.5, 3.75, and 5 GHz), on and planes of the folded antenna ( cm).

(a) = 2.5 GHz ( plane)

(b) = 3.75 GHz ( plane)

(c) = 5 GHz ( plane)

(d) = 2.5 GHz ( plane)

(e) = 3.75 GHz ( plane)

(f) = 5 GHz ( plane)
