Introduction to Some Types of Antennas

Millimeter-Wave Circularly Polarized Liquid Crystal Phased ArrayMillimeter waves refer to electromagnetic waves with frequencies ranging from 30GHz to 300GHz. The wavelength of these waves in a vacuum is roughly between...

What is a Good RF Cable? What are the Character...

Basic Structure of Coaxial Cables: · Inner Conductor (Innerleiter): Made of solid or stranded copper (Massiv oder Litze, Cu). · Dielectric (Dielektrikum): Made of PTFE (Polytetrafluoroethylene) or FEP (Fluorinated Ethylene Propylene Copolymer). · Shielding /...

Dual-Band 2.4G/5GHz Wi-Fi Antenna Sharing Issues

Currently, dual-band Wi-Fi modules support communication over both the 2.4GHz and 5GHz frequency bands. In the circuit design of these modules, there is an issue of antenna sharing between the...

Antenna Bandwidth

Definition: The bandwidth of an antenna refers to the frequency range within which the antenna’s performance parameters (such as input impedance, gain, VSWR, radiation pattern, etc.) meet certain specified requirements....

What is the principle of off-grid communication...

Off-grid communication technology is a form of communication that does not rely on traditional network infrastructures (such as cellular networks, Wi-Fi, etc.). It allows devices to communicate directly without the...

Why MIMO Antennas Require the Same Grounding

  Reasons for Shared Grounding in MIMO: MIMO antennas utilize multiple transmitting and receiving antenna elements to simultaneously send and receive multiple signals, thereby enabling spatial channel multiplexing. This technology...
