Enter R0 On the Enter Freq and Variables sheet. Roy and Chatterjee 3 also proposed log-periodic antennas with helical elements because the log-periodic helical antenna has a smaller transverse dimension. If a solution could be.

The log periodic antenna is used in a number of applications where a wide bandwidth is required along with directivity and a modest level of gain. There are several type of log-periodic antennas such as the planar trapezoidal zig-zag V-type slot and the dipole. A log-periodic antenna also known as a log-periodic array or aerial is a directional and narrow beam antenna that operates over a wide bandwidth.
