slot and with two slots of same physical patch dimensions. The positions of the slots were varied to see the eﬁect on the microstrip antenna bandwidth. It was observed that antenna performance could be controlled by introducing slots to a large extent in terms of increased bandwidth, improved VSWR, Return loss and radiation properties.

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 % Table 3 Diamond Slot Dimension [4] Increasing the size of inserted slot, effective radius of circular patch decreases which in turn increases the resonance frequency of antenna. With a=4mm and b=8mm input bandwidth approaches to 17.28%.With a=7mm and b=11mm input bandwidth approaches to 20.78%.Thus insertion of slot improves the input bandwidth. simulation results, we can say that the square slot circular microstrip antenna gives the better results op erati ng f q ucy 2.17GHz. Witho t changing the permittivity and height of the substrate, the effect of various parameters of Cmpa are studied. In simulation and measurement the return loss has a It has been shown that such fundamental scanning characteristics of an array consisting of microstrip antennas as the reflection coefficient, input resistance trends, scan blindness, and grating lobe effects are dictated by the interelement spacings and substrate parameters (height and relative permittivity) and not by the nature of the microstrip antenna element (patches or dipoles) [109].

effects of multipath in DGPS. In this paper we describe a new type of light weight, low profile GPS antenna system consisting of a two element concentric microstrip antenna array on a resistivity tapered ground plane that is effective in suppressing multipath through adaptive cross polarization filtering and antenna pattern shaping.

Jun 1, 2016 It provides dual-band operation by means of three narrow slots close and parallel to the patch Keywords: Microstrip antenna, Dual-band, Radiation pattern The effect of slot on the patch can be analyzed using the du Oct 16, 2020 after one publication of the mathematician Niels Fabian Helge von Koch, and it is Modified π-shaped slot loaded multifrequency microstrip antenna to reduce the metallic surface effect in the antenna performanc

The microstrip antenna is a relatively modern invention. It was invented to allow convenient integration of an antenna and other driving circuitry of a communication system on a common printed-circuit board or a semiconductor chip (Carver and Mink, 1981; Pozar, 1992).

The slots are numbered resembling slot 1, slot 2 and slot 3 as shown in figure 1. The location of the slot 1 and slot 3 with respect to the patch is defined by the dimensions d and l. the distance between slot 1& slot 2, slot 2 & slot 3 and slot 1 & slot 3 are denoted by d 12 , d 23 and d 13 respectively.

antenna. In this paper we have seen the effect of slot on microstrip patch antenna. By the use of slot we can enhance bandwidth, gain e.t.c.. Return loss is reduce. Axial ratio and radiation pattern is also improved. By the use of slot microstrip antenna can be used in many application. In this paper, a rectangular slot based microstrip patch antenna is designed and their analysis is done to evaluate their effect due to rotation of slot for wireless communication applications. The proposed antenna is suitable for • A rectangular type microstrip antenna with semi-ring shaped slot provides S 11 = -22 dB at 2.89 GHz and is can provides dual band result [7]. • The serrated-edge N-shaped slotted microstrip antenna feature S 11 = -21 dB at 2.1 GHz which can be used for WLAN, WMAN and Blothtooth applications [6].

Data obtained from simulation with variation of the height of the transformed antenna and its effect can be used to predict the antenna parameters including resonant frequency, return loss, power radiated, directivity and gain for a multilayer microstrip antenna subjected to the limits for the thickness of the superstrate layer (0.254mm-2.54mm).

Wideband U-slot microstrip antenna using CPW feed Abstract: The coplanar waveguide (CPW) has been researched due to several attractive features in comparison with the microstrip line. The attractions are wide bandwidth, better impedance matching, easy integration of solid state active devices and low radiation loss (see Nesic, A., 1983; Menzel, W. and Grabherr, 1991). 10/02/2021 rectangular microstrip antenna having two slots are listed below in millimetres.
