摘要： A monopole-type antenna (10) for multi- or wide-band use to transmit or receive radio frequency electromagnetic energy. A feed point (12) provides energy into the antenna or receives energy from the antenna. A driven radiating section (16) includes a first top-loading element (22) and a feed conductor (20) that electrically connects the feed point linearly to the first top-loading element, yet with the driven radiating section not electrically connected to a grounding surface (14). A parasitic radiating section (18) includes a second top-loading element (26) and a bridge conductor (24) that electrically connects the second top-loading element linearly to the grounding surface When energy is then provided at the feed point and conducted to the driven radiating section, it produces a first resonance mode, coupling at least some of the energy into and exciting the parasitic radiating section to produce a second resonance mode.

摘要： An antenna particularly suitable for use in radio frequency identification (RFID) transponders. First and second half portions each include nominally straight conductive sections primarily defining a radiating characteristic and nominally spiral conductive sections creating a positive reactive characteristic of the antenna. The straight conductive sections have feed points for connecting the antenna into the RFID transponder, and further connect with the respective spiral conductive sections. The first and said second half portions characterize the antenna as being a dipole type, and adding an optional loop section connecting the straight conductive sections can further characterize it as being of a folded dipole type.

摘要： A mode transducer for converting an electromagnetic wave between TE1,0 and TM0,1 modes. A rectangular waveguide guides the wave while in TE1,0 mode and a circular waveguide guides the wave while in TM0,1 mode. The rectangular waveguide and the circular waveguide are joined by a chamber to form a right angle structure. The chamber particularly includes offset walls distended away from proximal portions of the rectangular waveguide to convert the electromagnetic wave between modes. Two of the mode transducers rotatably coupled with a suitable rotation mechanism may be used as a rotary waveguide joint.
