With the development of offset reflector antennas with high performance, the growing demands for high frequency, low sidelobe level and reduced mass have brought structural design and manufacturing process stringent requirements. The coupled structural-electromagnetic problem of offset reflector antennas is studied to find out the prime structural factors which have a great effect on electromagnetic...
The demand on portable and user-friendly wireless communication devices has geared up accordingly which necessitates optimal miniaturised built-in antenna for mobile terminals. This paper presents a design of a miniaturized circular microstrip L-probe wideband patch antenna for achieving diversity operation at mobile terminals. The design is optimised to cover the UMTS, LTE and WLAN. A prototype is...
The polynomial and Pade rational function fitting models were employed to interpolate the scanned wide-angle ARC of radiating element in array environments as spatial dependence. Its efficiency and applicability was also proved in the calculation of mutual coupling between elements in large arrays with sparse samples of scanned ARC. A data compression ratio of 9 has been achieved.
The characteristics of antipodal Vivaldi antennas with different structures and the key factors that affect the performance of the antipodal antennas have been investigated. The return loss, radiation pattern and current distribution with various elliptical loading sizes, opening rates and ground plane sizes have been analyzed and compared using full wave simulation tool. Based on the parameter study,...
