Small 315 MHz Antenna Low-profile Antenna

What is a Small 315 MHz Antenna Low-profile Antenna?

The Small 315 MHz Antenna Low-profile Antenna style CTRF-ANTENNA-SMA-0315-0850-AP-S antenna item is a 2dBi gain antenna with a small size 8x50mm 315 MHz Dipole Antenna manufactured by C&T RF Antennas Inc for RF 315 MHz wireless data transmitting.

For the low-profile antenna same 315MHz ISM band frequency and small antenna size of 8x50mm, C&T RF Antennas Inc also provides an RF 315MHz SMA Rubber Duck Antenna style for your best choice.

How to choose the 315MHz antenna?

As the microcontroller generally uses 12MHz crystal as the starting vibration its own local oscillation is nearly 300MHz local oscillation frequency by the I/O port outward radiation of electromagnetic wave interference sources, resulting in a 315MHz receiving distance very close, or even can not receive.

Isolation: In order to effectively suppress electromagnetic interference from the MCU to the receiver module, it is recommended to use ① power isolation;

② port isolation; port isolation can be used triode or comparator. Practice shows that the effect of using isolation is very obvious.

315MHz antenna matching, the antenna’s 315MHz band, and machine band inconsistency, antenna impedance mismatch, all will seriously affect the call distance.

For users, when changing the 315MHz antenna, we should pay attention to tightening the antenna, in addition, we can’t just use the antenna provided by a non-manufacturer, and we can’t use the antenna that doesn’t match the frequency of the machine.

If the 315MHz transmitting power and receiver sensitivity are certain, the higher the gain of the 315MHz antenna used by both sides, the higher the frequency matches the distance reached.
