The elongated 44mm length optimizes gain performance (2.5 dBi) through meandered trace design while maintaining the narrow profile. This form factor is ideal for devices requiring edge-mounted antennas or installation along narrow PCB sections. The slim design also enables conformal mounting along device edges or curved surfaces without protruding into the main device volume.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: Is this antenna compatible with WiFi and Bluetooth simultaneously?\u003c\/p\u003e\n\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: Yes, the TX2400-FPC-4405 operates across the entire 2.4GHz ISM band (2400-2500 MHz) with VSWR ¡Ü2.0, making it fully compatible with WiFi (802.11b\/g\/n\/ax), Bluetooth (Classic and BLE 4.0\/5.0\/5.1\/5.2\/5.3), ZigBee (IEEE 802.15.4), and Thread protocols. The 50¦¸ impedance and IPEX-I connector ensure compatibility with dual-mode WiFi+Bluetooth modules from ESP32, nRF52, CC2652, and similar platforms. For devices with separate WiFi and Bluetooth radios, you may need two antennas or a diplexer to share a single antenna between both radios.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: How do I install this slim FPC antenna for optimal performance?\u003c\/p\u003e\n\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: For optimal performance, mount the antenna along the edge of your PCB or device enclosure, positioned on or near a ground plane (minimum 50mm ¡Á 10mm recommended for the elongated shape). Keep the antenna away from metal components, batteries, and LCD displays (10mm clearance). Clean the mounting surface with isopropyl alcohol, peel the 3M adhesive backing, and press firmly along the entire 44mm length. Connect the IPEX-I connector to your module's antenna port. The slim profile allows installation in narrow spaces, but ensure the 44mm length has adequate clearance for optimal radiation pattern. Verify performance using your module's signal strength indicators after installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: What is the expected WiFi range with this antenna?\u003c\/p\u003e\n\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: WiFi range depends on transmit power, receiver sensitivity, environmental conditions, and antenna placement. With typical WiFi transmit power (15-20 dBm) and proper installation, expect 35-90 meters indoor range and 120-220 meters outdoor line-of-sight. The 2.5 dBi gain provides approximately 1.8x range improvement compared to 0 dBi reference antennas. For USB WiFi adapters and wireless network cards, the slim profile enables optimal antenna positioning along the device edge, maximizing performance despite the compact form factor. Internal antenna placement typically reduces range by 20-30% compared to external antennas, but the enhanced 2.5 dBi gain helps compensate for this loss.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45203900629094,"sku":"10*TX2400-FPC-4405","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX2400-FPC-4405-_2_800x800_v2.jpg?v=1773473087","url":"https:\/\/cdsenet.store\/products\/tx2400-fpc-4405-2-4ghz-slim-fpc-antenna","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
