log periodic antenna design
It is a directional antenna with a wide bandwidth. The antenna is fed from an intermediate point a distance from the grounded end.

Since 1986 M2 Antenna Systems has been building high-quality antennas positioners and accessories for radio amateurs.
. Beginning with some of the earliest computer modeled and Computer Numerically Controlled CNC manufactured antennas Mike Staal K6MYC has applied his experience to design and build the finest directional linear cross-polarized and circular. Log-periodic dipole array Often confused with the Yagi-Uda this consists of many dipole elements along a boom with gradually increasing lengths all connected to the transmission line with alternating polarity. The antenna is shorter and more.

These cross polarized log periodic antennas are have higher gain and are more directional but work best if you have direct line-of-sight to the tower. The figure given above shows the radiational pattern for a bi-directional log-periodic antenna.
The antenna design is compact. The design has two advantages over a simple monopole. For bi-directional Log-periodic antenna the maximum radiation is in broad side which is normal to the surface of the antenna.
The following are the advantages of Log-periodic antennas. An inverted-F antenna is a type of antenna used in wireless communication mainly at UHF and microwave frequenciesIt consists of a monopole antenna running parallel to a ground plane and grounded at one end.
