The antenna peak gain is 13 dBi across the frequency band of 76 to 81 GHz. The radiation pattern of the
antenna in the horizontal plan (H-plane) and elevation plan (E-plane) is as shown in
Figure 2-16 and Figure
2-17 , respectively.
The beamwidth of the antenna design can be determined from the radiation patterns provided below. For
example, based on 3-dB drop in the gain as compared to bore sight, the horizontal 3dB-beamwidth is
approximately ±30 degrees (see
Figure 2-16 ), and elevation 3dB-beamwidth is approximately ±3 degrees (see
Figure 2-17 ). Similarly, the horizontal 6dB beamwidth is approximately ±45 degrees (see Figure 2-16 ) and the
elevation 6dB-beamwidth is approximately ±5 degrees (see Figure 2-17 ).
