CONSTITUTION: Vertical radiation element array modules(110-1-110-n) include the k number of broadband radiation elements(111-1-111-k). Broadband RF modules(120-1-120-n) are connected to each vertical radiation element array module. The broadband RF module comprises a high speed switcher(121), a broadband phase shifter(122), a broadband high power amplifier(123), a broadband circulator(124), a limiter(125), a broadband low noise amplifier(126). A first broadband transmission distributor(142) distributes one transmission signal. A left side second broadband transmission distributor(144-1) distributes an inputted left side transmission signal to each left side RF module. A right side second broadband transmission distributor(144-2) distributes an inputted right side transmission signal to each right side RF module. A left side wideband reception synthesizer(146-1) synthesizes the received output of each left side RF module. A hybrid(148) outputs a differential signal between the received signal of a left side synthesizer and the received signal of a right side synthesizer.

    • A circularly polarized wave dielectric horn parabola antenna is provided to reduce interference in an adjacent communication service area by reducing shield due to a sub reflection plate and improving a sidelobe radiation pattern. A circularly polarized wave dielectric horn parabola antenna includes a parabola-shaped main reflection plate(10), a circular waveguide-shaped feed horn(30), a dish-shaped sub reflection plate(20), and a polarizer(40). The parabola-shaped main reflection plate is made of an electric conductor. The circular waveguide-shaped feed horn is mounted on a central front surface of the main reflection plate. The dish-shaped sub reflection plate is connected to a circular waveguide(31) through a dielectric bar(23) on an aperture of the circular waveguide feed horn. The polarizer converts a linearly polarized wave into a circularly polarized wave in transmitting and converts the circularly polarized wave into the linearly polarized wave in receiving by being connected to the circular waveguide on a rear surface of the main reflection plate.

    • A repeater for frequency band conversion is provided to solve the problem of call congestion and avoid frequency interference by converting the whole or part of a service frequency band into a surplus frequency band among many other service frequency bands, relaying the converted frequency band, and converting it into the original frequency band again. In a mobile communication network which consists of a base station, a link repeater(20), and a plurality of shadow area repeaters, the link repeater(20) comprises the first diplexer(202), a downlink LNA(Low Noise Amplifier)(203), a downlink converter(204), a downlink BPF(Band Pass Filter)(205) and a downlink HPA(High Power Filter)(206). The first diplexer(202) separates downlink signals of a service frequency band of the base station from uplink signals of the service frequency band. The downlink LNA(203) amplifies the downlink signals. The downlink converter(204) converts the service frequency band into another frequency band by combining the amplified downlink signals with local oscillation signals. The downlink BPS(205) passes only downlink signals of a desired converted frequency band among the converted signals. The downlink HPA(206) amplifies the converted downlink signals outputted through the downlink BPS(205).
