摘要： Provided are a system and a method for determining an angle. The method includes: determining differences between signal strengths of incident waves received by a first directional antenna of an anchor node from a tested node and signal strengths of incident waves received by a second directional antenna of the anchor node from the tested node at multiple angles, wherein the first directional antenna and the second directional antenna are mounted at a same point, and an area formed by the first directional antenna is partially superposed with an area formed by the second directional antenna; and taking an angle corresponding to a minimum difference in the differences as an angle between a line connecting the anchor node and the tested node and a horizontal reference line. The present technical solution solves the technical problem that a high positioning accuracy and a low complexity of a positioning device cannot be realized at the same time in the related arts and achieves the technical effect of positioning a target accurately when the positioning device is low in complexity.

Furthermore, the antenna comprises a first and a second, identically designed individual antenna, the first individual antenna being connected to the first antenna gate and the second individual antenna being connected to second antenna gate. Additionally, an adjusted terminating resistor is connected to the load gate while the coupler transmits the signal to the first antenna gate at a phase angle of 0° and to the second antenna gate at a phase angle of 90°.

摘要： A portable communication device has an antenna configuration that allows to form various different antenna directivity configurations. In particular, a control device discriminates between a transmitting state and a receiving state of the communication device. As based thereon, it effects various non-uniform selection patterns among the directivity configurations.

摘要： An antenna circuit comprises an antenna element made up of a conductor bent into zigzag form and having a distributed inductance connected to a variable tuning unit including a variable reactance circuit and a reactance element. A plurality of dipole antennas comprising such an antenna circuit are grouped to form a phased array or Yagi antenna and voltage variable capacitors within the variable reactance circuits are interconnected. The grouped antennas are connected by a coaxial cable to a receiver which includes a generator circuit for generating a tuning control d.c. voltage for altering the capacitance of the variable capacitors. Control of the directivity of the grouped antennas is relieved by feeding slightly different tuning control d.c. voltages to each dipole antenna of the group so that the resonance of each dipole antenna is delayed to generate phase differences between the dipole antennas. The control is closed loop because a voltage difference signal is produced using the incoming radio wave and this voltage difference signal is used as a fine tuning signal.
