摘要： A broadband/multiband circular array antenna is disclosed. One embodiment comprises a circular directional array antenna comprising a driven omnidirectional traveling-wave antenna element coupled to a transceiver via a feed and a plurality of surface-waveguide elements symmetrically positioned about and spaced from the driven omnidirectional traveling-wave antenna element. Each surface-waveguide element receives a control signal configured to selectively alter its waveguide characteristics to electronically direct a beam to/from the array. The array provides a directionally controllable antenna beam with broadband/multiband frequency performance in a low profile design that is both economical and practical to produce and maintain.

摘要： A shared aperture, multifunction conformable antenna has a spiral-mode microstrip (SMM) antenna portion having a spacer for maintaining the SMM antenna in spaced relationship to a ground plane, with dielectric material therebetween. The SMM antenna portion is substantially surrounded by a loop antenna which is spaced therefrom and which is electrically connected to the spiral-mode portion by a high frequency choke to block FM broadcast band signals from the SMM antenna. An AM-broadcast-band-blocking capacitor functions to route AM signals to the SMM antenna portion. The spiral-mode antenna receives signals at frequencies above 300 MHz, the loop antenna receives signals in the FM band, and both the loop antenna and the spiral-mode antenna receive signals in the AM band.

摘要： The invention is a class of planar unidirectional traveling-wave (TW) antenna comprising a planar four-arm TW radiator ensemble, such as a 4-arm spiral, which is fed medially with a twin-lead feed connected with only a pair of opposite arms of the TW radiator, with the other two arms parasitically excited. The use of a mode suppressor enhances the purity of single-mode TW propagation and radiation. The twin-lead feed is connected with the balanced side of a balun, and is impedance matched with the TW radiator on one side and the balun on the other side. This simple feed structure using a single balun is generally smaller and much simpler, and thus much less costly than the conventional feed for a 4-arm spiral, which is a complex one-to-four power divider that contains hybrids, power dividers, couplers, matrices, etc.
