Directional Loop-Type Antenna Technologies Applied To Satellite And Terrestrial Integrated Mobile Phone Applications

In this article, a brief overview and discussion on some loop-type antenna technologies applied satellite and terrestrial integrated mobile phone applications is presented. By properly applying distinct characteristics of different resonant modes of various loop-type antenna designs as array elements, different application requirements of beamforming array antennas for satellite mobile phones including multi-band operations, dual-polarization or wide beam-scanning coverage could be achieved.
