    These antennas can provide narrow beamwidth and high power handling. In its simplest form, it is basically an open circuit wire with the signal being fed at the centre. Another antenna that makes use of passive elements is the Yagi-Uda antenna. If the graph of radiation of antenna is just a function of direction, then it is simply called as Radiation Pattern. An Radar Antenna has either receive energy from an electromagnetic field or to radiate electromagnetic waves produced by a high frequency generator. Usually a wave guide horn Antenna is used as a feed radiator for the paraboloid reflector Antenna. Good methodology to predict, test, and validate the power handling capability of FSS designs are hence highly desired for future FSS applications.

    Parabolic Antenna.It is because of this reciprocitythe Lens can be used as an Antenna, as the same phenomenon helps in utilizing the same Antenna for both transmission and reception.

    Phased Array Antenna.The slotted waveguide array antennas multiple slots on a single waveguide have potential of low cost, low weight, ease of fabrication, high gain, and easier amplitude tapering for extremely low sidelobe.

    Among the different types of reflector Antennas, the simple parabolic reflectors and the Cassegrain feed parabolic reflectors are the most commonly used.But if we consider an isotropic antenna, then its power density will be same at all points on the sphere of radiation.

    Popular antennas for the ground-based and airborne radar systems include horn antennas, reflector antennas, and slotted waveguide antennas (Skolnik, ).The rays that pass through the centre of the Lens are less refracted than the rays that pass through the edges of the Lens.

    In radio systems, many different antenna types are used with specialized properties for particular applications. Antennas can be classified in various ways.Wire Antennas come in different shapes and sizes like straight wire DipoleLoop and Helix.

    The antenna consists of a radiating element that splits the rods and makes current flow through the center by using a feeder at the transmitter out that takes.Electrically small loops of a single turn have small radiation resistance compared to their loss resistance.

    Radar antennas operate in two modes: scannig and tracking. In the scanning mode, all the targets in a section are illuminated periodically.Hence, the units of field strength are volts per meter.

    Wire Antennas. One of the most commonly used antennas are wire antennas. · Short Dipole Antenna. Perhaps the simplest of all antennas is the.There are many reasons to use antennas but the main reason is, they provide an easy method to transmit signals wherever other techniques are not possible.

    It has been known that when an antenna is situated in a proximity to the ground, its input impedance varies significantly with the antenna elevation and the type of the ground.

    The major disadvantage of using these antennas is their inefficient and very narrow bandwidth, which is typically a fraction of a percent or, at the most, a few percent.
