    Switched-beam antenna employing phased array of switched-beam elements

    A switched-beam antenna, by switching feed probes of patch antennas and phase shifters in a phased array of switched-beam elements, is presented. A single stub was employed to obtain impedance matching when all elements exist. Eight patterns are illustrated that are essential to control local oscillator signals in a circular antenna mixer array. © 2012 IEEE.

    A dual-band dual-feed switched-beam single patch antenna

    With the demand of dual-band operation in modern wireless communications, this paper proposes a low profile switched-beam patch antenna. It is a patch antenna that operates at 2.45 GHz and 5.8 GHz by designing microstrip transmission lines to short the low frequency patch with the high frequency patch for low-band operation. These transmission lines open circuit to separate the two patches to allow the high frequency patch operate solely. By selecting appropriate transmission line width and length, the antenna provides switched-beam patterns at the design frequencies. This antenna is significant in developing a low profile dual-band phase array of switched-beam elements.
