A slot antenna design was modeled 2 cm above the phantom. A 1 V voltage source was placed across the middle of the slot (Fig. 2A) and tuning was conducted by altering the length of the slot antenna. No additional matching circuits or baluns were used. • The INF and the slot antennas behave similarly. • The slot antenna can be considered as a loaded version of the INF antenna. The load is a quarter-wavelength stub, i.e. a narrowband device. • When the feed point is moved to the short-circuited end of the slot (or INF) antenna, the impedance decreases. When it is moved to the slot center (or open end of the INF antenna), the impedance increases Asked 8th Jan, 2020 in the project antenna design for medical applications. A circular ring slot antenna (CRSA) with microstrip feeding technique is analysed at 2.45 GHz frequency. In order to A new triple band circularly polarized square slot antenna design with crooked T and F-shape strips for wireless applications. Ahdi Rezaeieh, Sasan and Kartal, Mesut (2011). A new triple band circularly polarized square slot antenna design with crooked T and F-shape strips for wireless applications. Progress In Electromagnetics Research, 121, 1 Quad Antenna Design is one more free antenna design and analysis software for Windows. Quad antenna is a type of directional wire radio antenna mainly used on the VHF and UHF bands. This type of antenna is quite similar to Yagi-Uda antenna but instead of using a straight element, this antenna uses a square , round, or some other shaped closed looped elements . Engel NEOVH 300-antennen är en självinstallerbar antenn för satellitskivan, även om den är liten kan den ta emot positionen hos huvudsatelliterna med en stark signal. Användarvänlighet gör det idealiskt att installera var som helst, eftersom det kan installeras på bara några minuter. Antennen anpassas till mottagandet av fria kanaler, och även de som kodas om du prenumererar på en Hej alla, Jag skulle vilja design patch antenn med SMA-kontakt från markplanet. Hur kan vi simulera SMA kontakt med hjälp av fart? BTW.det kan förstås använda HFSS eller CST. Tack på förhand

Hi all, How can one design a Slot antenna in ADS as it allows to work in 2D only? how to create a 'slot' on the substrate? Which layer to select? Regards, Mariya

This implantable antenna is designed using thin and biocompatible substrate-superstrate layers to achieve human body insulation as well as flexibility. Despite showing good antenna performances, only the realized gain value is observed to be reduced (-12 dB). In addition, the multiple-point ablations and a larger MWA area could be achieved simultaneously by using the present tri-slot antenna. This study has a potential for the innovative design of MWA antenna for treatment of liver tumor with a large range and a long length. PMID: 28462497 [Indexed for MEDLINE] MeSH terms.

13/7/2001 · Design of miniaturized slot antennas Abstract: A procedure for the design of a novel small slot antenna is presented. Using this method enables us to achieve a perfectly matched antenna with a fairly high efficiency for a given arbitrary small size.

Antenna Structure and Design. The geometry of the proposed coplanar waveguide (CPW)-fed slot antenna is shown in Figure 1 with all dimensions in mm. This antenna has a simple structure with only one layer of dielectric substrate (RT/duroid 5880 PTFE glass fiber substrate) and metallization.

This paper presents a novel design of meander annular-ring slot antenna for circular polarized radiation. This antenna operates in the ISM (Industrial, Scientific and Medical) frequency bands, near 915MHz. The circular polarized radiation is achieved by feeding two orthogonal sides of an annular-ring slot. The required phase difference is achieved by adjusting the position of the feeding port. A meander …

antennas. The methods developed for efficient wideband patch antenna design are based on one or more of the following principles: A. Thick substrates of low permittivity are used. B. A scheme is devised to reduce the mismatch problem associated with thick substrates. C. By means of parasitic elements or slots, either new resonances
