Small antenna design pdf


A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor usually fed by a balanced source or feeding a balanced load. Within this physical description there are two distinct antenna types. The large self-resonant loop antenna small antenna design pdf a circumference close to one wavelength of the operating frequency and so is resonant at that frequency.

These antennas are used for both transmission and reception. Self resonant loop antennas are relatively large, governed by the intended wavelength of operation. They are mainly used at frequencies above 3.

5 MHz where their size is manageable. They can be viewed as a folded dipole deformed into an open shape.
