Abstract
The intrinsic disadvantages of patch antennas such as narrow bandwidth and nonuniform coverage are the reasons why this class of antenna has not been seriously considered for hand-held application. In this paper we present a new design for a U-shaped patch antenna that has a reasonable bandwidth, adequate coverage, and less interaction with the head and the hand of the user. Based on our earlier investigations (Manteghi 1997; and Manteghi et al. 1996) the important goals of the research reported here, were to obtain the maximum coverage and to properly correct the near-field pattern so that the undesired interactions with the user's head and hand are minimized.
贴片天线固有的缺点，如窄带宽和不均匀覆盖是这类天线没有被认真考虑用于手持应用的原因。在本文中，我们提出了一种新的u形贴片天线设计，该天线具有合理的带宽，足够的覆盖范围，并且与用户的头部和手的交互较少。基于我们早期的调查(Manteghi 1997;和Manteghi et al. 1996)，这里报告的研究的重要目标是获得最大的覆盖范围，并适当地纠正近场模式，从而最大限度地减少与用户头部和手部的不希望的交互。
