The antenna is located at the bottom of the smartphone and integrated with a metallic casing. Positive-Intrinsic-Negative (PIN) diodes are loaded at the dual-open slot and the folded U-shaped slot, respectively, which are used to realize four working states A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by an applied radio frequency current, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Slot antennas are usually used at UHF and microwave frequencies at which wavelengths are small enough that the plate and slot are convenie I would like to design a basic and simple slot antenna and thus found some reference papers to design the antenna. But, I am stuck with the dimensions of the slot to be used for the design. Fig. 2. Transmission line model of a slot antenna (a) half-wave slot antenna. (b) Inductively terminated slot antenna. (c) Two series inductive terminations. Fig. 3. Proposed antenna geometry fed by a two-port microstrip feed. This two-port geometry is used to find out the exact resonant frequency of the inductively loaded slot. B. Antenna Feed Tutorial 12 - Creating Slots in a Rectangular Patch Antenna Using CST.

Slot antennas in waveguides provide an economical way of the design of antenna arrays. The position, shape and orientation of the slots will determine how (or if) they radiate. Figure 3 shows a rectangular waveguide with a drawn with red lines snapshot of the schematic current distribution in the waveguide walls. slot radiator depends on Xo, on the length of the slot, on the capacitive loading of the slot and on the shape of the wings. The input impedance of a long slot antenna without wings with a slot 2' long is very nearly a pure resistance of around 250 ohms. A typical input impedance of a long slot antenna with wings is shown in Figs. 12 and 13.

For many designers, embedded antenna design is a very challenging task when designing embedded CHAPTER III Wideband Embedded Slot Antenna . 2450 MHz radio frequency (RF) exposure,” Physics in Medicine and Biology, vol. 51
connected to one side of the slot, and the outside conductor of the cable - to the other side of the slot. – The slot length is some (λ/2) for the slot antenna and (λ/4) long for the INF antenna. • The INF and the slot antennas behave similarly. • The slot antenna can be considered as a loaded version of the INF antenna. slot antenna. If by using an appropriate boundary condition, the magnetic current density at any arbitrary point along the length of a modified slot antenna can be maintained the same as the slot antenna, then it is possible to make a smaller slot antenna.

including medical sensors which constantly communicate with each other and the outside world. The performance of the existing antenna has been simulated using HFSS. The conductive surfaces and the ground plane of all three designed antennas are made out of copper tape with a thickness of 0.03 mm. The simulations were carried out using HFSS software and the fabric antennas characteristics were … 01/06/2007 The design of a reconfigurable three-dimensional (3-D) slot antenna for 4G and sub-6G smartphone application is presented in this paper.

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 .

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 High Frequency Design ANTENNA DESIGN where C 0 is a phase difference of currents feeding adja-cent slots, while d is a physical distance between these slots. One use for these antennas is in a thin array for radio-location devices. It is desirable in these applications to transmit and receive energy to and from a narrow sector of a free space. 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 Design And Analysis Of Compact U Slot Microstrip Patch Antenna 9 Figure 1: U -Slot loaded rectangular micro strip antenna These properties make FR4_epoxy very attractive to be used as substrates for the fabrication of antennas in applications requiring light weight, low loss, reduced bill of materials, preserving the electromagnetic performance. The effect of the antenna location on the human body should be considered in the antenna design process. The proposed antenna may be used in Medicare RF systems. A wideband tunable microstrip antennas with high efficiency for medical applications has been presented in this chapter. 2. Antenna Design. A schematic view of the proposed slot microstrip-fed planar antenna for quad-band application is shown in Figure 1.The antenna is printed on a 1.6 mm thick FR4 substrates with relative permittivity of 4.4 and loss tangent 0.02, while the overall areas are only 20 × 30 mm 2.
