	abstract = {A high-gain conical-beam traveling-wave array antenna based on a slotted circular waveguide is designed at the higher part of Ku-band. A single radiating element is formed by a ring of eight equally spaced slots fed by a circular waveguide. The excitation of the nonfundamental TM01 mode provides a uniform feeding distribution to each slot, generating an omnidirectional radiation performance. Thus, an array antenna formed by 48 rings of slots is proposed following the design rules of traveling-wave arrays. Every ring is properly designed to achieve a uniform power distribution and consequently maximum directivity for the array antenna performance. The distance between elements is also adjusted to obtain the better input matching response and mitigate the grating lobe appearance, generating a high-gain conical-beam radiation performance suitable for satellite and fifth-generation communications. The proposed antenna design has been manufactured in plastic material by using a 3-D printing process and plated by a spray metallization process. A -10 dB impedance bandwidth higher than 23\%, high-gain values around 13.5 dB, or total efficiency higher than 98\% has been achieved for the whole frequency band.},

	abstract = {In this article, a linearly polarized 4-element linear array in Ku band is presented. The single element consists of a circular microstrip patch capacitively coupled to a printed slot-end WR-51 waveguide. A corporate waveguide feeding network at H-plane is designed, which is composed of bends, T and Y-junctions. An optimization process with septums and irises is performed to get the best possible matching coefficient. An antenna prototype has been manufactured and measured. A maximum gain of 12.6 dBi, up to 91.6\% radiation efficiency and 13\% bandwidth (16 to 18.3 GHz) has been experimentally achieved.},

	abstract = {Propagation loss models for indoor environment are presented. The directive channel propagation loss in indoor environment at frequency bands of 3.3 GHz with a channel bandwidth of 200 MHz and 5.5 GHz band with 320 MHz bandwidth is measured using vertical polarizations. A Set of directive panel antennas is used in the measurements. Network analyzer is used in the measurement campaign. It is noticed that the propagation loss can be modelled by two slopes propagation model giving a rise to two propagation zones. It is noticed that the first zone of propagation is almost free space propagation zone. In general, the second zone has a higher deviation from the mean value of propagation loss. A new Hypo-Rayleigh distribution is proposed to model the channel induced fading in the second zone of the propagation zones.},

	abstract = {In this paper, we present two dual-mode channel filter topologies which are able to withstand more than 600 W in Ku-Band. The two different designs (one with elliptical cavities and the other one with rectangular cavities) implement the same transfer function: four order, elliptical response centered in 12GHz, with 40MHz bandwidth and two transmission zeros. It is shown that the critical dimensions for the power-handling of these filters are the dimensions of the input-output irises. In fact, in order to rigorously obtain these conclusions and to reach these high-power levels (including margins), it is essential to use the advanced numerical techniques described in the paper to predict the multipactor effect. Moreover, the standard approach for multipactor onset prediction based on computing the voltage inside the component is shown to be too conservative and difficult to apply to many practical filter configurations.},
