Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. Horn antennas - SlideShare You just clipped your first slide! Clipping is a handy way to collect important slides you want to go back to later.

Arbitrary antenna constructions can be used as a spotlight in an antenna field. For a phased array antenna is decisive that the single radiating elements are steered for with a regular phase moving and the main direction of the beam therefore is changed.
Types of Feeding in Microstrip Patch Antenna - Subha Sarkar
Slot antennas are easy to mass produce with any technology. The slot antenna can be cut out of whatever surface the antenna is mounted on. You tune the antenna performance by altering the slot size, shape and the design of the cavity behind it. Slot antenna radiation patterns are roughly omni-directional. Advantages and disadvantages of Microstrip Patch Antenna Drawbacks or disadvantages of Microstrip Antenna. Following are the disadvantages of Microstrip Antenna: The spurious radiation exists in various microstrip based antennas such as microstrip patch antenna, microstrip slot antenna and printed dipole antenna. It offers low efficiency due to dielectric losses and conductor losses. Slot antenna - Wikipedia A slot antenna's main advantages are its size, design simplicity, and convenient adaptation to mass production using either waveguide or PC board technology. Due to Babinet's principle a slot in a waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot. This can be used to determine the radiation ...
