EMF Radiation Protection Universal Phone Shield

The Simplest Way to Shield Yourself from Your Phone

Your phone emits Radio Frequency (RF) radiation from cellular, WiFi, Bluetooth, and 5G connections, and Extremely Low Frequency (ELF) radiation from its battery — continuously,  whenever it is on. An EMF blocking phone case is a more permanent case for your phone, while this EMF phone shield can be used as little or as frequently as needed with your phone.

The DefenderShield® Universal Phone Shield is a slim, flat panel lined with Ultra Armor+® Shielding Technology — the same multi-layer metallic composite used in DefenderShield’s wallet cases. It blocks up to 99% of directional EMF radiation from 0 to 110 GHz, covering all three 5G bands, 4G LTE, WiFi, Bluetooth, GPS, NFC, RFID, and ELF from the battery. The shielding performance is verified through FCC-accredited lab testing.

Think of it like a phone-sized umbrella — slide it between you and the source, and the exposure drops on your side while the phone keeps working normally on the other.

Position It, Pocket It, Forget About It

The shield measures just 0.125 inches thick and weighs 1.4 oz — thin enough to slide into a pocket alongside your phone, light enough that you will not notice it in a bag. Two built-in RFID-blocking pockets hold a credit card or ID behind wireless-skimming protection. Included elastic bands let you strap the shield to the phone when you want hands-free carry with continuous shielding.

Available in two sizes: Small (6” × 3”) fits most standard-sized phones, and Large (6.5” × 3.5”) covers larger models. The shield works with any phone, any brand, and any existing phone case — no swaps, no adhesives, no installation.

🛡 Ultra Armor+® — Full-Spectrum Shielding in a Flat Panel

The same shielding technology found in DefenderShield’s wallet cases, built into a slim shield instead of a phone case. Blocks up to 99% of directional EMF from 0 to 110 GHz — RF from every wireless protocol including high-band 5G and ELF from the battery, both of which are often ignored by other EMF protection brands. Verified by an FCC-accredited lab.

📱 Position Anywhere — Screen, Back, or Pocket

On a call, place the shield over the screen between the phone and your face. While texting, slide it behind the phone between the back and your hand. In your pocket or bag, strap it to the phone with the elastic bands so it stays between the device and your body. One shield, multiple positions, continuous coverage at the contact point.

🔒 Two RFID-Blocking Pockets

Slip a credit card or ID into either pocket for wireless-skimming protection while the shield rides alongside your phone. No separate RFID sleeve needed — the pockets are built in.

📡 No Signal Interference

The shielding, when placed correctly in between your phone and body, blocks EMF on  one side from emitting towards you. The phone’s antenna communicates from the opposite side. Cellular, WiFi, Bluetooth, GPS, and battery life stay exactly where they were before the shield was placed.

🦶 Ultra-Slim and Lightweight

At 0.125 inches thick and 1.4 oz, the shield adds almost nothing to the bulk of your phone. It slides into a pocket, fits inside a bag, and sits against your phone without noticeably adding any bulk to your device. No installation, no adhesives, no commitment to one phone model.

🧪 FCC-Accredited Lab Verified

The Ultra Armor+ Shielding technology used in this product is verified to block EMF radiation from 0-110 GHz by an independent FCC-accredited laboratory. DefenderShield publishes its results on its Technology page.

1. While on Calls — Place the shield over the screen.

Place the shield flat against the phone’s screen before holding the phone to your ear. The shield now sits between the phone and your head, reducing EMF exposure at the closest contact point during a call. Use the phone’s speaker or DefenderShield Air Tube Earbuds if you prefer hands-free.

2. While texting and browsing — Place the shield on the back.

Flip the shield to the back of the phone so it sits between the device and your hand, lap, or desk. The screen stays visible and touch-responsive while the shield blocks emissions heading toward your body.

3. In a Pocket or bag — Place the shield on the side closest to your body with the elastic bands on.

Strap the shield to the phone using the included elastic bands. Position the shield between the phone and your body — for example, place the shield facing your leg, with the phone on the other side, in a front pocket. The bands keep it in place so you do not need to adjust it every time you pull the phone out.

RFID Pockets

Slide a credit card or ID into either of the two built-in RFID-blocking pockets. The pockets sit flat against the shield and do not add meaningful thickness.

What the Shield Does Not Do

• It does not wrap around the phone — it shields one side at a time.

• It does not provide drop protection.

• It does not replace a phone case — it works alongside whatever case you already use.

• The shielding is only active when the shield is physically between your body and the phone.
