where ε.sub.r represents a relative permittivity of the dielectric, k represents a constant in a range of 0.15 to 0.70, and λ.sub.0 represents a free space wavelength of the signal.

An antenna device includes a dielectric resonator antenna configured to transmit and/or receive a first RF signal, a patch antenna pattern configured to transmit and/or receive a second RF signal, and at least partially overlaps the dielectric resonator antenna in a vertical direction, a first feed via configured to feed to the dielectric resonator antenna, and a second feed via configured to feed to the patch antenna pattern, wherein a frequency of the first RF signal is lower than a frequency of the second RF signal.

A wearable device includes a wearable body that in use is worn on or proximate a skin of a wearer and a wearable antenna embedded in the wearable body and insulated from the wearable body. The wearable antenna includes a microwave dielectric substrate having a first major surface, a second major surface opposed to the first major surface, and a relative permittivity of at least 90.

The invention relates to a dual polarized wideband array antenna using orthogonal feeding technique to have a low profile and a cosecant squared beam. The array antenna includes three main parts: the element antennas, the orthogonal feeding structure and the feeding network. The spatially orthogonal feeding structure is a transition between the microstrip lines on element antennas and the striplines on the feeding network. The top layer of the feeding network operates as a ground plane for the array antenna. Due to the disparities between the stripline lengths, the phase parameters of element antennas are optimized to create a cosecant squared radiation pattern.

Disclosed are exemplary embodiments of multiband WiFi directional antennas. In an exemplary embodiment, an antenna generally includes a base plate, a plurality of vertically polarized antenna element modules on the base plate, and a plurality of horizontally polarized antenna element modules on the base plate. Each antenna element module includes a radiating element and a ground plane/reflector. The antenna may be operable within at least a first WiFi frequency range and a second WiFi frequency range different than the first WiFi frequency range.

A dual-band antenna array may be provided. The dual-band antenna array may comprise a trace split, a first frequency branch, and a second frequency branch. The trace split may feed the first frequency branch and the second frequency branch. The first frequency branch may comprise a first frequency branch geometry that may cause a majority of a current of a signal fed into the trace split to feed the second frequency branch when the signal comprises a second frequency. The second frequency branch may comprise a second frequency branch geometry that may cause the majority of the current of the signal fed into the trace split to feed the first frequency branch when the signal comprises a first frequency.

An array antenna device includes a substrate, a strip conductor formed on one surface of the substrate, plural loop elements formed on the one surface of the substrate, and a conductor plate formed on the other surface of the substrate. Each of the loop elements has a circumferential length that is approximately equal to one wavelength of a radiated radio wave, and is disposed at such a position as to be coupled with the strip conductor electromagnetically, and the loop elements are arranged alongside the strip conductor at distances that are equal to the one wavelength.

An antenna for suppressing the gain of side lobes is disclosed, including a substrate, tandem antenna units arranged on the substrate and each including a first feed line and radiating elements, and the width of the radiating elements decreasing gradually from the middle of the first feed line to the two ends; and a power divider disposed on the substrate and including a feed port, a second feed line with middle connected to the fed port, and transmission lines, connected to the second feed line respectively. The output powers of the transmission lines decrease gradually from the middle of the second feed line to the two ends, and the transmission lines are respectively connected to the first feed lines. Thereby, the present invention can effectively suppress the gain of the side lobe both in YZ plane and the XZ plane, and improve target detection.

An electronic device may be provided with first and second sidewalls, a rear wall, and a display. Multiple antenna panels may be used to convey radio-frequency signals at frequencies greater than 10 GHz. A first antenna panel may radiate through the display while second and third panels radiate through the first and second sidewalls. The second and third panels may be tilted at non-zero angles with respect to the sidewalls. The non-zero angles may be of opposite sign. The non-zero angles may have the same magnitude. The magnitude may be equal to 15 degrees, as one example. Tilting the panels in this way may allow the panels to collectively cover as much of a sphere around the device as possible, including out of coverage areas behind the rear wall caused by conductive material in the rear wall, without requiring additional panels to be disposed within the device.

An antenna comprising: a longitudinal support member for supporting components of the antenna and a method of assembling such an antenna is disclosed. The components supported by the longitudinal member comprise: at least one signal feed probe configured to capacitively supply a signal to a corresponding at least one radiating patch; the at least one radiating patch mounted to at least partially wraparound the longitudinal support member; and signal supply circuitry for supplying a signal to the at least one signal feed. The signal supply circuitry is mounted on an outer surface of the inner longitudinal support member; and the longitudinal support member is formed of a conductive material and forms a ground plane for the antenna.
