In this paper, high spatial resolution imaging of a motion induced synthetic aperture radiometer with sparse rectangular array is presented. The imaging process is described including an observation scenario and image formation. The equivalent array factor and instantaneous spatial frequency coverage are presented to demonstrate the performance. Additionally, the differences between the proposed system...
By using a multilayered ferrite substrate, a compact internal DTV (digital television) antenna is proposed. The antenna is constructed on the ground plane of a clamshell-type mobile phone. It is suitable for a DVB-H band (VSWR<3), and it has over -10 dBi gain which is acceptable for a practical digital television signal reception.
This paper proposes the internal FM radio chip antenna miniaturization using magneto-dielectric. New digital multimedia broadcasting service including FM is now available with the development of VHF band and is expected to offer diverse opportunities to mobile businesses. FM radio frequency band ranges between 87.5 MHz and 108 MHz. However FM antenna is too big to fit inside mobile devices since a...
