The study on design and fabrication of a log periodic dipole array antenna for aviation industry / Mohd Hairi Selamat

Antenna is the device that is the heart of communication systems, being used to transmit and receive radio signals. An antenna forms the interface between the free space and the transmitter/receiver. The choice of a particular antenna depends on factors such as gain, radiation pattern, polarization,...
