2.4 GHz Microstrip Patch Array Antenna with Integrated Power Divider

2.4 GHz Microstrip Patch Array Antenna with Integrated Power Divider

High-Gain | Low SLL | Perfectly Matched | Compact & Ready-to-Deploy

Revolutionize your 2.4 GHz ISM-band systems with this precision-engineered 4-element microstrip patch array. Designed and fully validated in CST Studio Suite, it delivers 12.53 dBi peak gain and -2.8 dB side-lobe level in an ultra-compact footprint.

Smart Design Features

Integrated corporate-feed power divider ensures equal amplitude/phase to all 4 patches → symmetrical pattern, no grating lobes.

Quarter-wave transformers provide perfect 50 Ω matching across the band.

FR-4 substrate (εr = 4.3) – cost-effective, widely available, proven reliability.

Compact layout: fits inside < 120 × 120 mm — ideal for drones, IoT gateways, access points, and mesh nodes.

Radiation Pattern (Phi = 90° cut)

Broadside beam with smooth roll-off.

Low back-lobe (<-15 dB) → reduced EMI.

No nulls in upper hemisphere → uniform coverage for ceiling/wall mounts.

Applications

Wi-Fi 6/6E access points

Drone telemetry & video links

Smart city sensor networks

Industrial IoT gateways

RFID & asset tracking

Ready for Production

Full CST project files included (geometry, mesh, far-field data).

Gerber & DXF exportable.

Validated with 702k mesh cells → simulation = measurement confidence.
