Array antennas have been widely studied and used for base stations because they are effective in solving the problems of multipath fading and co-channel interference and improving performance and capacity in wireless communication systems. However, little effort has been made for developing array antennas suitable for mobile handsets, because of the difficulties such as the limited space on the handset...
A simultaneous measurement method using a parallel modulated probe array is proposed to measure the electromagnetic field radiated by antennas at different locations simultaneously. Each modulated probe is excited by a local signal with different frequency, so that the received intermediate frequency (IF) signal contains different frequency components which indicate the relative magnitude of the radio-frequency...
