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 ... What are the advantages and disadvantages of slot antenna?

A slot antenna consists of a metal surface, usually a flat plate, with a hole or slot cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic ... The Pros and Cons of Slot Antennas.

Advantages. Mobility – user device can be moved easily within the wireless range. Neat and easy Installation – since no cable running here and there, just start up the wireless device and you’reMore user supported – cable device have limited slots whereas wireless does not. Disadvantages. What are the advantages and disadvantages of radio… The biggest advantage is that they can operate day and night and in nearly any type of weather.Deserts areas are a go-to for radio telescope construction. The arrays must also be made up of several to dozens of large and precise antenna to pick up the wavelengths because they're very low energy. Advantages and Disadvantages of LAN Local Area Network Advantages of LAN or Local Area Network. 1. Resource Sharing. Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. This will reduce cost of hardware purchases.

slot antenna[′slät an‚ten·ə] (electromagnetism) An antenna formed by cutting one or more narrow slots in a large metal surface fed by a coaxial line or waveguide. Slot Antenna an antenna in which apertures, or slots, for the radiation or reception of radio waves are cut in the conducting surface. A slot antenna may be a metallic wave guide, a ... Microstrip antenna - Wikipedia Advantages. Microstrip antennas are relatively inexpensive to manufacture and design because of the simple 2-dimensional physical geometry. ... These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is loaded by material with increasing relative dielectric constant.
