Channel Static Antennas for Mobile Devices

Channel static antennas are considered for mobile devices. The antenna keeps the wireless communication channel static by performing a counter-movement that is opposed to movements of the device that might be caused by a user. The feasibility of the concept is demonstrated for linear movement in an office environment. Channel measurements are performed with quarter wavelength monopole antennas in the 2.4GHz ISM frequency band. A channel model for the wireless communication channel of mobile devices with channel static antennas is proposed based on these measurement results.
