✦ Synopsis

In this paper, a modified microstrip-fed dipole antenna is presented to improve the stability of the radiation patterns and increase the usable bandwidth. The proposed antenna consists of two parallel dipoles of different lengths to obtain two main resonances. The antenna produces almost similar radiation patterns around the two resonances, and as a result, high pattern stability is realized. The presented antenna provides a wide impedance bandwidth of 90%. In addition, it provides endfire radiation patterns with high gain, low cross-polarization level, and wide beamwidth, which make this antenna a very good candidate for phased arrays and spatial power combiners.
