However, if the communication wavelength is much larger than the antenna length, the radiation efficiency of the antenna is very low – a crucial concern for the energy-limited nanomorphic cell. Another difficult problem for nanomorphic communication is the background thermal radiation. Interestingly,...
Asymptotic method is used to find the far-zone radiated waves and the periodic guided waves, which are used subsequently to determine the antenna radiation characteristics including gain (directivity) patterns, efficiency, and periodic guided wave power pattern. Of particular interest is the photonic ...
A low-cost compact planar leaky-wave antenna (LWA) is proposed offering directive broadside radiation over a significantly wide bandwidth. The design is based on an annular metallic strip grating (MSG) configuration, placed on top of a dual-layer grounde
The weak resonance frequencies are the small antenna radiation which is excited by the field in the cavity. 前者携带有天线几何结构及其构成材料的信息,后者含有天线辐射特性方面的信息。 更多例句>> 3) radiation efficiency 辐射效率 1. A uniform representation in the calculation of seismic radiation ef...
With the rapidly developing of microstrip antenna in the military and commercial fields,narrowband and low radiant efficiency become the bottlenecks for its further development. 随着微带天线在军事和商业领域内迅速发展,微带天线的频带窄以及辐射效率低成为制约其发展的两大“瓶颈”,因此展宽频带和提高辐射效率...
