What is a Patch Antenna?

A patch antenna, also known as a microstrip patch antenna, is a low-profile antenna consisting of a metallic patch mounted over a ground plane. It excels in applications requiring compact size and directional performance, making it ideal for 5G, 4G, and 3G networks. Unlike bulky dipole antennas, patch designs radiate perpendicular to the patch surface, offering high gain (typically 5-10 dBi) in a flat form factor.

These antennas operate on principles of resonance, where the patch acts as a resonant cavity excited by a feed line. Common materials include FR4 substrates for cost-effectiveness or Rogers laminates for high-frequency precision. At AsiaLeren, our patch antennas support frequencies from 698 MHz to 6 GHz, covering sub-6 GHz 5G bands and legacy cellular standards.

Patch Antenna FAQ

What is a patch antenna?

A patch antenna is a miniaturized antenna using microstrip technology, featuring a metal patch on a dielectric substrate over a ground plane. Its compact, lightweight design suits integration into PCBs for communications, IoT, and navigation.

What are the main features of patch antennas?
Key features include miniaturization (sizes from mm to cm), directional radiation for better efficiency, multi-band support (GPS, WiFi, 5G), and stability in -40°C to +85°C ranges. They integrate easily with mass production and reduce device complexity.

What applications are patch antennas used for?
Patch antennas power consumer electronics (smartphones, wearables), in-vehicle GPS/V2X, IoT sensors, medical devices, drones, and aerospace comms. They're perfect for space-limited setups needing reliable signals.

Are AsiaLeren patch antennas compatible with 5G, 4G, and 3G?
Yes, our patch antennas support multi-band operation across 5G sub-6GHz, 4G LTE (698-2700MHz), and 3G frequencies. Combo designs ensure backward compatibility for seamless network switching.

How do patch antennas differ from other antennas like omnis or panels?
Unlike omnidirectional antennas, patch antennas provide focused directional radiation with higher gain in specific directions, lower profiles, and easier PCB integration. They're lighter and more stable than helical or yagi types.

What is the typical gain and size of your patch antennas?
Models offer 5-9 dBi gain with sizes from 50x50mm to 150x150mm. High-gain versions suit point-to-point links, while compact ones fit drones or routers.

Can patch antennas be used outdoors?
Absolutely – IP67-rated models withstand weather, vibration, and extremes. Ideal for vehicles, base stations, or industrial IoT.

What connectors and mounting options are available?
Standard SMA, N-type, or RP-SMA connectors with bracket, magnetic, or flush mounts. Custom options for MIMO setups.

How to install a patch antenna for best performance?
Mount high with line-of-sight to signals, use low-loss cables, and align for directional focus. Test VSWR (<1.5:1) post-install.

Do you offer customization or bulk orders from China?
Yes, as a Shenzhen-based manufacturer, we provide OEM customization (frequencies, shapes) with low MOQs (100+ units), fast shipping, and 2-year warranties.
