摘要： The invention describes a broadband multi-dipole antenna that has low input reflection coefficient, low cross polarization, rotationally symmetric beam and constant beam width and phase center location over several octaves bandwidth. The dipoles are fed from one or a few feed points, and they may with advantage have log-periodic dimensions. The antenna is more compact, has lighter weight and is cheaper to manufacture than other solutions. It is very well suited for feeding single, dual or multi-reflector antennas.

摘要： An antenna on a removable card An antenna on a removable memory card (1) is intended for the creation of contactless communication channel of the mobile communication device. The antenna is in the form of a high-frequency transformer (2) with an oblong ferrite kernel (3) with resonantly tuned primary winding L1. The emitted signal is brought to the primary winding L1. The secondary winding L2 is left open circuited, without closing the load circuit in a contact way, without ohm load; it emits electrical field with its outputs. The high-frequency transformer (2) can be in the form of auto-transformer with one winding. The signal emitted in the direction towards the removable memory card (1) can be received through the auxiliary winding L3 or through an independent receiving antenna (8). The secondary winding L2 can have a larger number of loops than the primary winding L1 or it can be formed by only one winding in the form of a pipe.

摘要： An object is to provide a radio frequency IC device capable of achieving impedance matching between a radio IC chip and a radiation plate in a wide frequency band, and achieving desired radiation characteristics over a wide range of frequencies. Another object is to provide a radio frequency IC device and a radio communication system that allow both long-distance and short-distance communication and, in particular, allow short-distance communication using a small amount of energy. A radio frequency IC device includes an electromagnetic coupling module (1) having a radio IC chip (5) and a feed circuit board (10), and a radiation plate (15). An annular electrode (25) is disposed to be coupled to both a feed circuit of the electromagnetic coupling module (1) and the radiation plate (15). The radiation plate (15) serves as an electric-field radiation plate for long-distance communication, while the annular electrode (25) serves as a magnetic-field radiation plate for short-distance communication. The feed circuit board (10) may be removed, so that the radio IC chip (5) is coupled to the annular electrode (25) directly or with an interposer disposed therebetween.
