chip antinna Vs wire antina, which would be better?
which of them would have better range? either chip or wire
The radiation pattern for the whip antenna is similar to that of a dipole. That is to say, it is shaped like a donut. Thus, the performance of a module using a whip antenna, is relatively insensitive to its orientation in the plane that is perpendicular to the whip antenna. On the other hand, the radiation pattern of the chip antenna is not as uniform as that of the whip antenna. Therefore, certain orientations will achieve better performance than others. As our evaluation was performed, the orientation was selected to achieve the best performance. ...After reviewing Table 1, we can make several important observations. • The whip antenna has a range advantage over the chip antenna, but only outdoors. • The XBee-PRO can achieve more range than the XBee. • The XBee-PRO and XBee both achieve more range outdoors than they do indoors. The whip antenna on the XBee module affords additional range in outdoor applications. However, it also occupies more space. If more range is required, and space is a constraint, then the XBee-PRO with a chip antenna may be more appropriate. On the other hand, if more range is a requirement and cost, not space, is the constraint, then the XBee with a whip antenna may be the best choice. It should also be clear that the XBee-PRO can achieve superior range when compared to the XBee. Thus, if the application requires more range than the XBee can provide, then the XBee-PRO with a whip or a chip antenna could be used. Again, the chip antenna is best for tight spaces, while the whip antenna achieves more range.
the tabel is for series 1 radios, can i get that of series 2 ?
