Can I achieve long range reception of Bluenrg-355MT with a ceramic chip antenna?

[EShei.1]

Hello! I'm using module Bluenrg-355MT in my project. There is the antenna ACAG0801-2450-T on my board. This antenna transmits enough over a long distance (D>250m). But reception of this antenna is not more than 15m. Is it possible to achieve long range reception with such type of antennas? Have you tested this module with small size chip antennas? Thanks in advance!

With antennas, size matters.

To maximise range, you're going to need the best antenna gain you can get.

Also, it depends on the whole transmission path from end-to-end - see "Link Budget"

"This antenna transmits enough over a long distance (D>250m). But reception of this antenna is not more than 15m"

Sounds like the problem is at the other end - you need to turn the power up at the other end!

Hello,

Please also note that not only antenna gain matters.

It is important to consider antenna matching to ensure proper impedance adaptation.

In theory both RF SOC output and antenna input are 50ohms but in reality this is never the case.

Two or three discretes components are usually enough to ensure this proper matching (and be sure your antenna will effectively radiates at 2.45GHz)
