Abstract
Omni-directional base stations are needed in many emerging wireless co mmunication systems. This paper presents the first adaptation of a qua si-optical oscillator array for this purpose. A 28 GHz active oscillat or element containing a modified Vivaldi endfire antenna is utilized a s the unit cell. Twelve of these are incorporated into the circular ar ray, which is powered from a single de power supply. The array has a h igh combining efficiency and remains frequency-locked over a span of 6 00 MHz.
