“…6 (b). Equation (1) had been already obtained in Japan to obtain the input impedance of slot antennas earlier than the paper of Booker [16] as pointed out by Mushiake [17], and the paper by Asami et al [18] was a more detailed report of the unpublished earlier paper. However, the structures reported in these papers had been restricted for the thin slot antennas and the thin wire antennas.…”

SUMMARYInvention and development of the Yagi-Uda antenna in Tohoku University, Japan are described. Communication experiments in VHF and UHF frequency bands using transmitter and receiver developed in the same university as well as the Yagi-Uda antenna are also presented. Then, self-complementary antennas, which is the frequency independent antenna invented in Tohoku University are described. Analysis methods of large loop antennas is also presented.

“…The analysis is carried out by King and Wu's three term assumption for the current [8][9][10]. Thus, for a single centre-fed dipole in free space [11] [ ] In the above equations (4) and (5), V is the applied voltage, h is the distance along the dipole axis measured from the feeding point, l is the half-length of the dipole, a is the radius of dipole, β=2π/λ and the other symbols are as defined below [11].…”

Log Periodic array Antenna is one of the most important and commercially used antennas for T.V. reception. It is used in VHF and UHF bands. Although the analysis of this antenna is reported in literature, the data of self impedance & mutual impedance is not fully available. But, this data is useful for the optimal design of the antenna. In view of this the array above is considered and the analysis is carried out in the present work. The computed data for Self-Impedance as a function of lengths of elements and frequency and the Mutual Impedance as a function of spacings of elements is presented.

Today, the technological evolvements have contributed to the development of Ground Penetration Radar (GPR) systems. GPR systems are used in a lot of fields such as; military field, civilian life and commercial activities. Besides, antenna design for the GPR system is so important. The designed GPR antennas should have lower than 1 GHz start frequency for more penetration and getting information about the object in the deeper layers of ground or any obstacle. Also, with wide band properties obtaining high resolution data would be available. In this paper, a Self-Complementary bow tie antenna is proposed. The start frequency of designed antenna is from 0.45 GHz and it works frequency independently. Simulation and fabrication results are presented for designed antenna.
