摘要： Disclosed is an antenna with an extended electrical length, including radiators (110, 210, 310), (410 and 510) having S-shaped or spiral-shaped cells (112, 212, 312 and 512). The cells (112, 212, 312 and 512) are formed on the front surface of the boards (120, 220, 320, 420 and 520), and two or more of the cells are connected in series by connectors (114, 214 and 314) formed on the rear surface of the board. Furthermore, the antenna includes a ground stub (150) and a parasitic element (160) electromagnetically coupled to the radiators (110, 210, 310, 410 and 510), and has a good radiation characteristic. Furthermore, the antenna can include the cells (112, 212, 312 and 512) of different sizes and can thus have a multi-band characteristic.

摘要： The present invention provides a multiple band antenna, including a first radiation element adapted to resonate at a first resonant frequency band by employing a resonant length, which is reduced by a coupling effect with a neighboring radiation element, a power feed unit coupled to one lower side of the first radiation element, a first inductor coupled in series to the other lower side of the first radiation element, a second radiation element adapted to face the first radiator to thereby obtain the coupling effect, wherein the second radiation element has a predetermined lower portion coupled to the first inductor, a second inductor having one end coupled in series to a predetermined upper portion of the second radiation element, and a third radiation element coupled to the other end of the second inductor, wherein the third radiation element operates as one radiation element together with the second radiation element and resonates at a second frequency band.

摘要： There is herein disclosed an interdigital capacitor, an inductor, and an LH transmission line and a coupler using the interdigital capacitor and the inductor. The interdigital capacitor comprises two finger sets which are substantially disposed in parallel with each other. Fingers of each finger set are overlapped at outer edges thereof with each other to thereby generate capacitance. The inductor is formed substantially spirally inside the transmission line, so that it can have a large inductance in a compact shape and can be used in a broad frequency band. The LH transmission line has a broad frequency band in a compact shape, which includes interdigital capacitors connected in series with each other and inductors connected in parallel with each other. In addition, the coupler employing the LH transmission line has an excellent couplability.
