Problem addressed
The millimeter-wave 5G bands are operated over a wide bandwidth from 24 GHz to 41 GHz. Mobile devices need antenna arrays with broadside and end-fire radation patterns for communicating with other devices at different directions. Design of wideband and end-fire antennas and arrays are challenging.
Innovation
- By employing the complementary antenna concept and using asymmetrical substrate integrated coaxial-like feed line, a wideband and high-gain antenna element is realized on dielectric laminates. The antenna has a compact volume and can be used alone or as the radiator element of an array design.
Key impact
- Wide bandwidth, high gain and high radiation efficiency
- High front-to-back ratio
- Can be integrated with Antenna-in-Package design
Application
- Mobile communications
