Abstract: A mounting structure of a grille for mounting the grille onto a device comprises a fixing member having a fixing aperture for receiving a fastening means and a guiding member extending away from the fixing member for inserting into an opening on the device so that the grille is placed in a pre-determined position and the fixing aperture is aligned with a corresponding fastening means receiving slot on the device to facilitate the fastening of the grille onto the device. The fixing member and the guiding member are integrally formed as a single piece on the grille.

Abstract: According to various aspects, exemplary embodiments are disclosed of antennas, which may be configured to be low profile, ultra-wideband, and/or omnidirectional. In an exemplary embodiment, an antenna may be low profile and may be configured to be operable omnidirectionally within an ultra-wideband frequency range including frequencies from about 350 megahertz to about 6000 MHz. The antenna may include a printed circuit board (PCB) having a first side and a second side opposite the first side. The first side of the PCB may include a radiating element, a first patch with an additional radiating arm, a shorting line, a stub along the shorting line, and a microstrip line. The second side of the PCB may include a ground plane and a second patch.

Abstract: Exemplary embodiments are provided of antenna housing assemblies. In an exemplary embodiment, an assembly generally includes a radome having an outer surface, an inner surface, a first end, and a second end opposite the first end. A top cap is coupled to the first end of the radome via an ultrasonic weld joint. A first sealing member is disposed about the top cap such that the first sealing member is positioned between the top cap and the inner surface of the radome. A bottom cap is fastened to the second end of the radome via an ultrasonic weld joint. A second sealing member is disposed about the bottom cap such that the second sealing member is positioned between the bottom cap and the inner surface of the radome. Exemplary methods of assembling antenna housings are also disclosed.

Abstract: Exemplary embodiments are provided of antennas and antenna systems including the same. In an exemplary embodiment, an antenna generally includes an upper radiating patch element, a ground plane spaced apart from the upper radiating patch element, and a feed point positioned adjacent the ground plane. A first feeding element electrically couples (e.g., via proximity coupling or direct galvanic coupling) the upper radiating patch element to the feed point. A second feeding element electrically couples (e.g., via proximity coupling or direct galvanic coupling) the upper radiating patch element to the feed point. A shorting element electrically couples (e.g., via proximity coupling or direct galvanic coupling) the upper radiating patch element to the ground plane. In other exemplary embodiments, the antenna systems include one or more ground planes and one or more antennas.

Abstract: According to various aspects, exemplary embodiments are disclosed of antenna systems. In an exemplary embodiment, an antenna system generally includes a ground plane and first and second antennas. A first isolator is disposed between the first and antennas. A second isolator extends outwardly from the ground plane. The antenna system is configured to be operable with low passive intermodulation.
