摘要： A transmission line pair has two transmission lines placed adjacent to each other in parallel to a signal transmission direction of the transmission lines as a whole. Each of the transmission lines includes a first signal conductor which is placed on one surface of a substrate formed from a dielectric or semiconductor and which is formed so as to be curved toward a first rotational direction within the surface, and a second signal conductor which is formed so as to be curved toward a second rotational direction opposite to the first rotational direction and which is placed in the surface so as to be electrically connected in series to the first signal conductor. A transmission-direction reversal portion in which a signal is transmitted along a direction reversed with respect to the signal transmission direction of the transmission lines as a whole is formed so as to include at least part of the first signal conductor and part of the second signal conductor. Thus, the transmission line pair is enabled to maintain successful isolation characteristics.

摘要： A slot antenna according to the present invention includes: a ground conductor 12 provided on a rear face side of a dielectric substrate 101, the ground conductor having a finite area; a slot 14 which recesses into the ground conductor 12, beginning from an open-end point on a side edge of the ground conductor 12; and a feed line 261 for supplying a high-frequency signal to the slot 14, the feed line 261 intersecting the slot 14. At a first point near the slot, the feed line 261 branches into a group of branch lines including at least two branch lines, such that at least two branch lines in the group of branch lines are connected to each other at a second point near the slot to form at least one loop line 209. A maximum value of a loop length of each loop line 209 is prescribed to be less than 1× effective wavelength at an upper limit frequency of an operating band of the slot antenna. In the group of branch lines, any branch line that does not constitute a part of the loop line 209 but terminates with a leading open-end point has a branch length which is less than a ¼ effective wavelength at the upper limit frequency of the operating band.

摘要： With a differential feed line 103c, slot resonators 601, 603, 605, and 607 are allowed to operate in pair, a slot length of each resonator corresponding to a ½ effective wavelength during operation. Slot resonators which are excited out-of-phase with an equal amplitude are allowed to exist within the circuitry. Thus, positioning condition of selective radiation portions 601b, 601c, 603b, 603c, 605b, and 607b in the slot resonators is switched.
