摘要： An improved glass mount antenna system employs a pair of coupling plates having planar cavities disposed therein with any ground plane portion thereof. Surfaces of the coupling plates which are opposite that of the ground plane include a printed exciter strip which crosses the planar cavities to thereby provide an effective communications antenna assembly which is inexpensive to manufacture and especially well suited for high frequency communication operations such as the ultra-high frequency microwave bands of between 1.5 GHz and about 2.4 GHz which are currently intended for PCN/PCS communications.

摘要： A multi-band antenna is provided that operates in non-harmonically related frequency bands. The antenna includes a primary antenna element for a first frequency band of the non-harmonically related bands, said primary antenna element extending perpendicularly from a ground plane, the primary antenna element electrically isolated from the ground plane, a plurality of secondary elements extending from the ground plane parallel to the primary antenna element and arranged in a circle around the primary antenna element, each of said plurality of secondary elements electrically isolated from the primary antenna element and ground plane and a plurality of antenna elements for a second frequency band of a higher relative frequency than the first frequency band, the plurality of high frequency antenna elements extending parallel to the primary and secondary antenna elements and disposed in a circle around the secondary antenna elements.

摘要： A cost efficient multi-band antenna, for use with non-harmonically related frequency bands, for example dual Wi-Fi frequency bands. An antenna element extends away from a ground plane. A sleeve positioned coaxial about the antenna element is spaced apart from the antenna element and the ground plane. Dimensions, spacing and dielectric constants of the antenna element, sleeve and any dielectric spacers are selected to tune the antenna to the desired frequency bands. Further, the ground plane may be the radiating element of, for example a GPS module or SDAR antenna to create a triple frequency band antenna assembly.

摘要： A low cost window-mounted antenna system for mobile communication systems operating at frequencies in and above the 1.5 GHz band includes an annular ring aperture coupler fabricated on printed circuit boards on each side of the window, with a microstrip line etched on each of the printed circuit boards. A collinear array-type whip antenna with a 1/2-wavelength lower section is used with the coupler. A coplanar waveguide trace is printed on the outside coupling unit to form an impedance matching network for the active element. The RF signal is thus electro-magnetically coupled through the window.
