Design of an Impulse Radiating Antenna Using a Curved TEM-Wire Fed Parabola

Figure 8

Comparison of radiation patterns with different 𝑁_𝑒 values at 3 GHz. Peak directivities decrease with larger 𝑁_𝑒 and main lobe widths increase. The parameter 𝐿 in (1) is set to be 350 mm. The other values except 𝑁_𝑥=𝑁_𝑦=𝑁_𝑒 remain unchanged.

(a) 𝑁_𝑒 = 1, peak value 28.3 dBi

(b) 𝑁_𝑒 = 2, peak value 27.9 dBi

(c) 𝑁_𝑒 = 3, peak value 26.6 dBi

(d) 𝑁_𝑒 = 4, peak value 25 dBi
