COMPARATIVE STUDY OF RADIATION PATTERN OF SQUARE SPIRAL ANTENNA

K. P. Tiwari

Abstract :

 

Frequency– independent antennas are used in applications that require grater bandwidths. Bi– conical spiral antennas and log–periodic antennas are often classified as independent of frequency, since the spiral antennas can be built as planers structures in accordance with the principle. Aluminium Nitride has been used as antenna substrate of thickness 2mm relative permittivity 8.2 and tangent loss (tanδ) 0.002. Measured loss in 1.9dB at 8GHz Width of the strip spiral have been taken d₁ = 1 mm d₂ = 2 mm and the spiral spacing 4mm. A strip is mounted at the center point. Various parameters are studied for the spiral antenna. The effect of feed gap, which is critical parameters for the performance of antenna, is studied for different frequencies.
