This antenna is designed on FR-4 substrate. It has dielectric constant 4.4 and thickness 1.6 mm. copper material is used for ground plane and patch. We provided microstrip line feeding to this antenna.

All goals must be measurable to then measure the progress towards the successful outcome, to measure progress is to monitor and access success and achievement.

On old radios the antenna was detrimental to the radio’s operation. Today, the antenna is not necessary. AM radio does not have as good of quality as FM but it can travel farther distances. FM signals can be interfered by things such as mountains or other barrier

The amplitude affects the strength of the force, that is the length of the force vectors in the electromagnetic wave. The wavelength of the wave depends only on the frequency with which the electron in the transmitting antenna is oscillating up and down; and the speed of light.

Window embedded wire antennas have been introduced at FM frequencies for low-power or receive-only applications. The power transmitted by the army radios at VHF and UHF frequencies can exceed tens of watts. At these power levels, it is of crucial importance to isolate the interior of the vehicle from the antenna radiation. In addition, this isolation eliminates the affects of the cabin interior and passengers on the antenna input impedance and radiation pattern. Hence a transparent ground plane will be needed behind the radiating element to reduce the radiation inside the vehicle and at the same time increase the directivity of the antenna. A wire-mesh or a more sophisticated band-selective ground plane can be used as the reflecting element. A meshed patch antenna on a mesh ground plane can provide the required isolation with the cabin interior. However because of the sub-wavelength dimensions of the armored windows at VHF and UHF frequencies a patch antenna, if feasible, cannot provide the one octave bandwidth required by the army radios. In this paper a monopole bow-tie antenna backed by a cavity (armored window) is proposed. Because of the limited thickness of the window glass, the radiation element and the transparent ground plane need to be placed very close to each other. Therefore the gain and/or the

The tangential components (seen in Figure 3.11), which are in phase, means that the resulting fields combine to give maximum radiated field normal to the surface of the structure. Hence the edges along the width can be represented as two radiating slots, which are λ / 2 apart and excited in phase and radiating in the half space above the ground plane. The fringing fields along the width can be modeled as radiating slots and electrically the patch of the microstrip antenna looks greater than its

Between the telephone and the telegraph, one object sits perfectly between, claiming the award for best electrical invention. The modern day radio is a perfect hybrid between these two extravagant things. Of course, many inventions are to be thanked for leading the way to this timeless possession, and the same can be said about the radio itself. Still used today, the applications are endless.

Wireless Networks can be broadly classified into three categories: Infrastructure based networks, Wireless LANs and Ad Hoc Networks. Infrastructure based networks are traditional cellular systems which require base station infrastructure. Wireless LANs are very flexible within the reception area. It requires low bandwidth when compared to wired networks. Ad Hoc networks are useful when the infrastructure is not available, impractical or expensive to build.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

There are several substrate materials that can be used for fabrication antenna. Some of them are low cost while the others are highly expensive. Each substrate being used has its own advantages and disadvantages. The dielectric of each substrate plays an important role in the

With the recent surge in wireless communications, the radio industry has seen an increase in the number of different communication standards each requiring its own specific hardware and processing. Our project addresses the need for radio interoperability with these various standards through the development of hardware generators for a software defined radio (SDR) system. These hardware generators will be created using Chisel, a hardware construction language. When given a set of parameters or constraints, the hardware generators will automatically output circuit designs for the given application thereby accelerating the hardware design process and introducing a new method for multi-standard support. Specifically, our team will focus on the development of generators for the system’s beamforming and MIMO blocks.

CE1.20 Three virtual sectors (Usually each sectors uses 60 degree angle projection) were implemented on the antenna and each sector is shown in different colour based on the design. In the above figure, light green shows the area covered by the light green sector and so on. The coverage of the each sector can increase or decreased based on the frequency given to each of them. The design and

Phased array antennas are to be used, whose array elements in a pattern (linear, circular, planar) collectively give a directional pattern and by changing the phase of the current to these elements the radiation pattern can be steered. Algorithms that is needed to achieve this is – DOA (Direction of Arrival) and Adaptive Beamforming algorithm.
