Where Is the Antenna on My Android Phone?

Android Phone

Each signal on an Android phone is delicately transferred through an antenna, making its design and placement a bit complicated. If you cannot make cellular calls and use Bluetooth or WiFi, you would suspect the respective antenna could be the problem. But how would you know the location of these Antennas on your device?

Quick Answer

The primary cellular antenna on Android is located behind the back cover on the lower left or right side of the battery. The Bluetooth and WiFi antenna is located behind the plastic frame of the motherboard. 

In this article, we will identify where is the antenna on your Android phone by following some easy step-by-step methods. We will also discuss various types of antennas found in an Android smartphone.

Types of Antennas in an Android Phone

There are multiple antennas installed on your Android phone, each of which is built for a specific type of connectivity purpose mentioned below.

Primary Cellular Antenna

A primary cellular Antenna helps you make and receive phone calls or send and receive text messages through transmitting and receiving signals. If you cannot receive 2G, 3G, or 4G, signals on your Android phone, it’s probably because your phone’s primary cellular antenna is not working.

GPS Antenna

GPS antenna was standard in the old cellphones but is still featured in some modern smartphones. The GPS antenna only receives signals in Android phones. 

WiFi and Bluetooth Antenna

The WiFi and Bluetooth antenna is pretty common in new-age Android phones and is not dependent on the primary cellular antenna signal reception. So, if your primary antenna is not working, you would still be able to use Bluetooth and WiFi on your Android device.

Finding Antenna on Android Phone

If you’re asking yourself where the antenna is on your Android phone, our two step-by-step methods will help you to achieve this task without any hassle.

Method #1: Finding Cellular Antenna on Android Phone

You can find the primary cellular antenna in your Android phone by following these easy steps.

Step #1: Heating the Back Cover

Take out the sim card and turn off your Android phone. Use the heat gun to heat the back cover and hover it on the corners to completely remove the adhesive. Perform the heat gun process for at least one minute.

Step #2: Removing the Back Cover

Attach a suction cup to the back of your phone. Slide a plastic tool (such as a guitar pick) between the back cover and your phone’s frame

Carefully slide the plastic tool around the back cover to detach it from the phone. If the back seems stiff, keep reheating to make it loose. Pull the suction cup slowly, and the back cover will come off.

Step #3: Disassembling Motherboard 

Unscrew all the screws you see on the exposed back of the Android phone. Carefully pull the white frame by pushing the motherboard inside to reveal the electronic components of your device.

Step #4: Identifying Antennas on Android

In the lower left and right side of the battery, two screws are found holding the primary cellular antenna of your Android phone.
