In this paper, the regular microstrip dipole antenna shape is modified by adding upper and lower triangular patches, which makes it look like a rhombus. The rhombus shape is chosen because of its wideband characteristics over the rectangular one. The presented antenna provides a wide bandwidth of more than 100%. The measured and computed VSWR and radiation patterns for one element and the mutual coupling for two elements are presented in the paper. The proposed antenna provides endfire radiation patterns with wide beamwidth and low cross polarization level which make it a good candidate for phased arrays and radar systems. © 2006 Wiley Periodicals, Inc.
