The techniques described herein relate to a Radio Frequency (RF) communication module for a hand-held mobile electronic device. The Radio Frequency (RF) communication module includes a circuit board and a plurality of antennas disposed on a top side and bottom side of the circuit board. The plurality of antennas comprise a first subset of antennas comprising end-fire antennas and a second subset of antennas comprising broadside antennas. The first subset of antennas and the second subset of antennas also have a bandwidth of approximately 40 percent. The Radio Frequency (RF) communication module also includes a shielded area comprising circuitry coupled to the circuit board for controlling the antennas.

Antenna systems, devices, and methods for providing both end-fire mm-wave high-frequency signals and low-frequency RF signals from a collocated antenna array in which at least one high-frequency antenna element and a low-frequency antenna element are spaced apart from one another. Grating strips are positioned between the high-frequency antenna elements and the low-frequency antenna element, the grating strips being spaced apart from one another by a defined spacing. The grating strips are configured such that a signal wave from the high-frequency antenna element propagates through the low-frequency antenna element.

Radar loss caused by a windshield having laminated glass in a vehicle is suppressed with a simple configuration.

An antenna's radiation section is disposed inside the windshield of a vehicle having a plurality of layers. The radiation section not only radiates radio waves but also receives reflected waves of the radio waves from a target. A distance measurement information generation section is connected to the radiation section. The distance measurement information generation section measures a distance to the target on the basis of the radiated radio waves and the reflected waves from the target and generates distance measurement information.

An orthogonally polarized Yagi-like MIMO antenna system and a triangular printed wideband Yagi based MIMO antenna system, respectively, and methods for making the antennas. The orthogonally polarized Yagi-like MIMO antenna system includes two slot round loop elements on a top side of a substrate. Each slot round loop element has two input ports and two slot reflectors.
