Antenna Considerations
The choice of antennas is a critical and
often overlooked design consideration.
The range, performance, and legality of
an RF link are critically dependent upon
the antenna. While adequate antenna
performance can often be obtained by
trial and error methods, antenna design
and matching is a complex task. A
professionally designed antenna such as
Figure 24: Linx Antennas
those from Linx will help ensure maximum
performance and FCC compliance.
Linx transmitters are capable of achieving output power in excess of some
legal limits. This allows the designer to use an inefficient antenna, such as a
loop trace or helical, to meet size, cost, or cosmetic requirements and still
achieve full legal output power for maximum range. If an efficient antenna is
used, then some attenuation of the output power will likely be needed. This
can easily be accomplished by using the LADJ line or a T-pad attenuator.
For more details on T-pad attenuator design, please see Application Note
AN-00150.
A receiver antenna should be optimized for the frequency or band in which
the receiver operates and to minimize the reception of off-frequency
signals. The efficiency of the receiver’s antenna is critical to maximizing
range performance. Unlike the transmitter antenna, where legal operation
may mandate attenuation or a reduction in antenna efficiency, the receiver’s
antenna should be optimized as much as is practical.
It is usually best to utilize a basic quarter-wave whip until your prototype
product is operating satisfactorily. Other antennas can then be evaluated
based on the cost, size, and cosmetic requirements of the product. You
may wish to review Application Note AN-00500 “Antennas: Design,
Application, Performance” and Application Note AN-00501 “Understanding
Antenna Specifications and Operation.”
