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

Figure 4

Simulated and measured gain patterns for three different frequencies (3, 4, and 5 GHz), on and planes of the original differential antenna.

(a) = 3 GHz ( plane)

(b) = 4 GHz ( plane)

(c) = 5 GHz ( plane)

(d) = 3 GHz ( plane)

(e) = 4 GHz ( plane)

(f) = 5 GHz ( plane)
