We propose a novel feed network for a $2{ imes}2$ array antenna to form a sectoral conical beam. The proposed feed network, which is a symmetrical structure, consists of four $90^{circ}$ hybrids, a crossover, and four $90^{circ}$ delay lines. To verify the performance of the feed network a $2{ imes}2$ array antenna and the feed network are fabricated on a microstrip structure, and the radiation patterns are measured at the center frequency of 2.57 GHz. The maximum radiation is measured at the $45^{circ}$ elevation angle and at the $45^{circ}$, $135^{circ}$, $225^{circ}$, and $315^{circ}$ azimuth angles depending on the choice of the input port of the feed network.
