Formulations Comprising Psychotropic Drugs And Selenium

Abstract

There is disclosed an antenna device 14 comprising a pair of dielectric resonator antenna elements 1, 1', each element 1, l' comprising a dielectric resonator provided with a feed 4, 6, 7 and a conductive backwall 3, wherein one element is configured as a transmit antenna 1 and the other as a receive antenna 1', and wherein the elements 1, 1' are disposed such that the conductive backwalls 3 directly face each other in a substantially parallel configuration. Several such antenna devices 14 may be formed as an array, with side-wise adjacent devices 14 having an orientation of the transmit and receive elements 1, 1' reversed, thereby giving near omnidirectional coverage with much reduced coupling between transmit 1 and receive 1' elements.
