Abstract: PROBLEM TO BE SOLVED: To provide a microwave device that consists of parallel plate resonators and is capable of mode selection. SOLUTION: This invention relates to the microwave system having some parallel plate resonators including at least one dielectric board at both sides of which pole plates made of a metallic strip are configured. At least either pattern of the 1st and 2nd plates in each of some of the parallel plate resonators is shaped or formed so as to shut off a current line of a undesirable mode at its maximum point in order to suppress at least one undesirable mode TM 210, in other words, either of the 1st and 2nd plates include current interruption notches (2A, 2B, 2C, 2D).

Abstract: The wireless relates to a method for utilizing the available bandwidth in a wireless communication system that comprises a first (A/B) and a second (C/D) communication device intended to transmit information to each other, where each device (A/B; C/D) simultaneously can transmit on a first frequency and receive on a second frequency. Based on the need of the respective devices to transmit information within a particular interval of time, the said interval of time is divided up into a number of sub-intervals, the first device simultaneously transmitting on both the first and the second frequencies within a number of the said sub-intervals, and the second device simultaneously receiving on both the first and the second frequencies during these sub-intervals. The invention also relates to devices and modules intended to be incorporated in such a system.

Abstract: The present invention relates to a microwave arrangement which comprises a device including a number of dielectric substrates, electrodes arranged on either side of said dielectric substrate(s) and microwave transmission means for coupling microwaves into and out of said arrangement. The substrate comprises SrTiO3 crystals or a dielectric material with similar properties and first and second connection means connected to each of the electrodes for application of a voltage, temperature regulating means for cooling down the device so that through application of a voltage or external electrical pulses the dielectric constant of the substrate can be switched between a first stable state and a second stable state giving a digital, switchable arrangement.
