Antenna design Clause Samples
Antenna design. The RPD antennas shall be designed on printed circuit boards. The vertical beam width of the RPD at the 6dB points of the two-way pattern shall be 65 degrees or greater. The antennas shall cover a 90 degree horizontal field of view. The sidelobes in the RPD two-way antenna pattern shall be -40dB or less.
Antenna design. Antennas for the MHN system have 19-dBi beamforming gain for the transmission and 22-dBi gain for the reception. Since the transmission should meet the regulatory output power in terms of EIRP (Equivalent Isotropic Radiated Power), the maximum output power plus the beamforming gain is less than 36 dBi. On the other hand, the reception needs to have a slightly larger beamforming gain to achieve the coverage requirement in the Table 10. The structures of TX and RX antennas are shown in Figure 35 and Figure 36, respectively. Details on dimension is not described, but TX antenna is surely smaller than RX antenna in size due to the different beamforming gains.
