Yagi-Uda Antenna is one of the most important and commercially used antennas for T.V. reception. 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 ...
of 36 dB and a side lobe level of −20 dB, the radar consists of 1024 pairs of crossed Yagi-Uda antenna elements (1024 pairs of crossed-half-wave dipoles) arranged in a 32 × 32 matrix over an area of 130 m × 130 m. The radar beam can be tilted up to 20° in steps of 1...
Dual-band antenna and challenges associated with its global optimization: (a) geometry, (b) family of responses corresponding to random designs allocated over the assumed design space, (c) selected characteristics. The target operating frequencies: 2.45 GHz and 5.3 GHz are indicated by vertical line...
The reconfigurable concept of a graphene loaded patch antenna with increasing gain is proposed in this paper. We have developed the patch antenna with inset feed for THz band application for which graphene load is used to obtain the reconfigurable characteristic. It has been shown that by increasin...
IMPACT OF ELEMENT LENGTHS AND SPACINGS ON THE PERFORMANCE CHARACTERISTICS OF YAGI-UDA ANTENNAA. A. Raji
Several parasitic tripoles of unequal lengths are added in front of an active tripole or a large ground plane. Attention is focused on an antenna with a wire reflector. An integro-differential equation has been developed for the analysis of the circular polarization Yagi-Uda antenna array. ...

Microwave Antenna Characteristics in the Presence of an Intervening RidgeUsing two transmitters and two receivers operating in the 2000 mc./sec. region, the following experiments were carried out, in the presence of an intervening ridge, between terminals which were 14 km. apart: (i) Using ...
A three‐element quasi Yagi‐Uda antenna array with printed metamaterial surface generated from the array of uniplanar capacitively loaded loop (CLL) unit‐cells printed on the substrate operating in the band 25‐30 GHz is proposed. The metamaterial surface is configured to provide a high...
