摘要： An antenna arrangement having a ground plane (30, 212) a PIFA antenna (15, 240) arranged parallel to the ground plane, and a quarter wave slot antenna (220), arranged to radiate or receive with orthogonal polarisations, the ground plane being rectangular and having higher and lower E field regions (25), caused by use of either of the antennas. The feed (205, 218) of at least one of the antennas is located in the lower E field region caused by the other of the antennas, to provide improved isolation for a compact size. This can be useful for diversity or dual band use, for mobile handset devices.

摘要： An RF device includes a substrate and a series circuit of a tunable RF component and a DC blocking capacitor. The series circuit is arranged on the substrate and couples an RF signal terminal to a fixed voltage terminal that is electrically isolated from the RF signal terminal. The tunable RF component is coupled to the RF signal terminal, the DC blocking capacitor is coupled to the fixed voltage terminal and a driver terminal is coupled to the tunable RF component.

摘要： An antenna arrangement comprises a ground plane (14) and a planar antenna element (30) mounted spaced from and parallel to the ground plane. An open-ended slot (16) is provided in the ground plane (14), the slot being coextensive with an edge portion of the ground plane and having a first end (18) opening into the edge portion of the ground plane and a second closed end (20). An antenna feed (22) is coupled to the slot at a location intermediate the first and second ends. The planar antenna element is connected by an electrically conductive wall (28) to the edge portion of the ground plane, the wall (28) being co-extensive with the slot (16). The combination of the slot shape, slot location and the wall serves to increase the bandwidth of the antenna arrangement.
