A dielectric resonator antenna having a resonator formed from a dielectric material mounted on a ground plane with a conductive skirt. The ground plane is formed from a conductive material. First and second probes are electrically coupled to the resonator for providing first and second signals, respectively, to or receiving from the resonator. The first and second probes are spaced apart from each other. The first and second probes are formed of conductive strips that are electrically connected to the perimeter of the resonator and are substantially orthogonal with respect to the ground plane. A dual band antenna can be constructed by positioning and connecting two dielectric resonator antennas together. Each resonator in the dual band configuration resonates at a particular frequency, thereby providing dual band operation. The resonators can be positioned either side by side or vertically.

The present invention represents an integrated antenna assembly comprising a cellular communications antenna and a satellite communications antenna. Such an antenna assembly can, therefore, be used for communications over either frequency range. A wireless telephone using this assembly can, therefore, operate with either a terrestrial cellular communications system or a satellite communications system. In a preferred embodiment of the invention, the satellite communications antenna is a quadrifilar helix antenna and the cellular communications antenna is a sleeve dipole. The whip portion of the sleeve dipole is positioned axially in the center of the quadrifilar helix antenna. This orientation permits operation in both the satellite and cellular frequency ranges without significant electromagnetic coupling.

An antenna is described. The antenna includes a planar circular structure. The antenna also includes a radiating element located at the center of the planar circular structure. The antenna further includes one or more parasitic elements located on a contour around the radiating element. The parasitic elements are aligned in parallel direction with the radiating element. The parasitic elements protrude from the planar circular structure. The antenna includes switches separating each of the one or more parasitic elements from ground. A switch in a first position creates a short between a parasitic element and ground. A switch in a second position creates an open circuit between the parasitic element and ground.

A compact Ku band microwave diplexer configured as a three port surface mount component on a miniature alumina substrate. Input signals occurring at a common port having frequencies within a first pass band are passed to a second port while being isolated from signals occurring at a third port. Signals occurring at the third port are passed to the common port while being isolated from the signals at the second port. A microstrip dual spur line filter is used combined with open circuit stubs to provide enhanced second harmonic suppression on the transmit side, while using a coupled line microstrip filter on the receive side. This approach allows for compact size and automated component assembly through pick and place and reflow manufacturing techniques.

A coaxial to microstrip transition is introduced in a multi layer mixed dielectric printed circuit board environment that provides a 50 Ohm impedance system between a coaxial antenna feed and a surface mount diplexer at Ku-band frequencies. The 50 Ohm transition from the coaxial antenna feed to the diplexer at microwave frequencies lossy FR-4 style laminate is provided by constructing a PCB internal coax using the center conductor of the antenna feed and a dual ring of plated through hole VIAs. The transition from the PCB internal coax to the microstrip section of the high frequency laminate PCB layer uses a “D”-style opening in the ground layer and a VIA ring arrangement between the layers to optimize or tune the performance of the transition. Additional features in the interface construction are implemented to guaranty that its microwave and mechanical performance does not degrade in extreme environmental conditions.

A multi-channel wireless communication device includes first and second antenna elements. The first antenna element, being of a first type, transmits and receives a first wireless communication signal over a first predetermined wireless channel. The second antenna element, being of a second type different than the first type, transmits and receives a second wireless communication signal over a second predetermined wireless channel, different from the first predetermined wireless channel.
