This article demonstrates the simulation of an electrically large antenna. The design and numerical results are courtesy and permission of Chelton Antennas, France. The antenna operates at 8 GHz and was simulated using the CST MICROWAVE STUDIO® (CST MWS) Transient Solver which is, as a result of its efficient memory scaling, ideal for such electrically large structures. In this case, the antenn...

In this article, an optimized E-shaped patch antenna for Bluetooth (2.4–2.484 GHz) and UWB (3.1–10.6 GHz) applications with WLAN (5.15–5.825 GHz) band-notched characteristics is proposed. The dimensions of the E-shaped antenna structure in addition to the position of the slotted C-shape in the ground plane are optimized using recent optimization techniques such as Modified Particle Swarm Optimi...

New pickup designs for a Bunch Arrival time Monitor (BAM) at the Free Electron Laser in Hamburg (FLASH) have been developed and simulated [1, 2] with CST PARTICLE STUDIO R ©. With regard to the signal characteristics and manufacturability a cone-shaped pickup was selected as a prospective candidate. At high frequencies, small manufacturing tolerances might have great influence on the pickup sig...

We characterized a BNL 1.3GHz halfcell SRF gun is tested for GaAs photocathode. The gun already was simulated several years ago via twodimensional (2D) numerical codes (i.e., Superfish and Parmela) with and without the beam. In this paper, we discuss our investigation of its characteristics using a three dimensional (3D) full-wave code (CST STUDIO SUITETM).The input/pickup couplers are sited sy...

This paper presents two-surface multipactor discharge with two-frequency rf fields using Monte Carlo simulations and Computer Simulation Technology (CST) Particle Studio. The effects of the relative strength phase second carrier mode on susceptibility time dependent physics are studied. Compared to single-frequency operation, shrinkage regions is observed for different configurations operation....
