An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and Web1 Jan 2013 · Parasitic antenna array Angle of arrival Mutual coupling Download chapter PDF 2.1 The Smart Antenna Divide Smart antenna systems have emerged in the early 1970s [ … Web19 Feb 2024 · While for the proposed antenna, in the band higher than the second resonant frequency, the radiation performance is improved due to more radiation apertures of parasitic patch arrays, so only a very small part of the radiation waves can be offset by that of the microstrip patch in broadside direction. Therefore, the gain deterioration is removed. fhf ch forbach
