Direct feed biconical antenna as a reference antenna
2011 IEEE International RF & Microwave Conference, 2011Antenna factor is the main parameter in EMC measurement. Therefore, accurate and low uncertainty antenna is important in order to gain a reliable antenna factor. Direct feed biconical antenna has low uncertainty because balun can be eliminated in the design. Furthermore, the biconical antenna has fix phase center.

Additive manufacturing of antenna-feed chains
2017 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP), 2017This paper reports on the additive manufacturing of waveguide components and subassemblies for antenna-feed chains operating in the Ku, K and Ka bands. The aim of the activity is the monolithic manufacturing of an entire dual-band antenna-feed chain working in K-Ka bands.

UWB planar monopole antenna with differential feed
2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016This paper presents a differentially driven planar monopole antenna for UWB (Ultra-Wideband) applications. The dimensions of the antenna structure are first studied to achieve wideband characteristics with good impedance matching. The goal is to find dimensions which satisfy the UWB demands but also to show that antenna size can be miniaturized by ...

Multifeed EBG dual band antenna to feed a reflector antenna
2011 41st European Microwave Conference, 2011In this paper, we present the design of a multibeam reflector antenna fed by a multifeed dual band Electromagnetic Band Gap (EBG) antenna to achieve a high gain multispot coverage for space applications. First, we design a dual band EBG antenna in monofeed configuration.

Feed network for antenna decoupling
2009 Loughborough Antennas & Propagation Conference, 2009A decoupling network for improving the isolation between two highly coupled antennas is proposed. In this method the input signals are combined linearly so that the mutual coupling between the ports becomes zero. The scattering matrix of the network is found using a mathematical procedure and has been demonstrated in this paper for a previously ...
