2.2 Modelos de Patches Modificados Alguns modelos de patches têm um fator de qualidade inerentemente baixo. Isso ocorre devido à pouca energia armazenada próximo ao patch e à alta radiação. Os anéis anular, retangular e quadrado, o patch de quarto de onda e a antena com fenda em U são alguns exemplos de estruturas modificadas [1],[2].

The microstrip antennas have been designed on ε r = 4.3 and h = 1.53 mm. It has been observed as the slot length increases the resonant frequency shifted to the lower side by 19.05 % and 5.04 % The second alternative design consists of a Rotman lens and a single-pole–quadruple-throw (SP4T) switch. This design is very straightforward and offers a completely symmetrical device, exhibiting uniform loss for all scan beams. The number of scan angles reduces to four, pointing to ±6° and ±18° from boresight axis. Dipole, Slot & INF antennas • Slot antenna: a slot is cut from a large (relative to the slot length) metal plate. • The center conductor of the feeding coaxial cable is 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 …

In this design, we assume the left and right sides of symmetric u- slot patch antenna has not enough effective role in antenna structure to increase bandwidth . We 

In recent years, the U-slot patch antenna established itself as a versatile, low profile and cost effective antenna that can be fine- tuned for ultra-wideband  The slot method used in the design of microstrip antenna operates to add up the “Double U-Slot Loaded Stacked Microstrip Patch Antenna with 2 × 2 Array for  26 Oct 2015 Abstract. Many techniques have been proposed to design microstrip patch antennas with multiband characteristics. In the proposed antenna 

This paper presents a design and simulation of rectangular micro strip patch antenna at 2.5 GHz frequency range for wireless communication that provides a radiation pattern along a wide angle of beam.

The design of single U-slot antenna structure is presented in Fig. 1 and corresponding dimensions are length of the patch (L) is 52 mm, width of the patch (W) is 71 mm, length of vertical outer slot (ls 1) is 40 mm, length of horizontal outer U-slot (bs 1) is 18 mm, width of outer slot (ws 1) is 4 mm, and offset feed length (d) is 9 mm.

The U-slot patch antenna was originally developed as a single-layer, single- patch wideband antenna. It has recently been shown that it can also be designed to 

In the proposed antenna design, a combination of dual U-slot and multiple layers is used to get multiple bands and wide bandwidth. A multiband triple-layer probe   The U-slot patch antenna was originally developed as a single-layer, single- patch wideband antenna. It has recently been shown that it can also be designed to  12 Oct 2020 Complete series of all types of antenna designs in HFSS and CST from beginner to pro level!
