In this paper, design and development of broadband blade monopole antenna covering 0.5-1.5 GHz is presented with simulated and measured results. Blade monopole antennas are preferred antenna configurations for airborne platforms due to lower drag offered by them. The basic antenna element configuration is optimized by simulation studies using CST Microwave Suitetrade EM simulation software.
In this paper, the design and development of broadband, helical elements dipole antenna is presented. It offers higher gain compared to its conventional tubular elements counterpart of same physical dimensions. Both types of the dipole antennas, one with tubular elements and other with helical elements were constructed. These antennas were compared for their electrical parameters in the frequency...
This paper presents the design of 256 (16 times 16) elements planar microstrip array antenna at K-band frequencies using corporate feeding network. The array antenna has been designed and developed for miniaturized satellite communication (SATCOM) ground terminals. The impedance bandwidth achieved for VSWR Lt 2.0 is 540 MHz (~ 2.7%). The achieved mid-band gain of the array antenna is about 29 dBi...
Digital broadcasting is the distribution of audio and/or video signals which transmit programs to an audience. The era of total digital broadcasting, from program production to digital receivers, will soon be upon us as a result of advances in image compression technology, higher integration and improved performance in LSI devices, and the rapid progress in digital technologies including the development...
In this paper, an inward scaled loop antenna (ISLA) is presented. It is created by successive scaling and rotating and fitting the scaled copies of a wideband loop antenna (WBLA) in the empty space available in it. The overall size of the antenna remains the same as that of the WBLA. The advantage of an ISLA is its improved input performance as compared to the WBLA. Impedance bandwidth of the order...
In this paper, design and development of rectangular sleeve dipole antenna covering more than an octave bandwidth (850-2500 MHz) is presented with measured results. Here a rectangular box type of sleeve is proposed over the cylindrical dipole elements. This antenna is compact in size and covers more than 2.9:1 bandwidth with maximum VSWR 3:1. The antenna was first simulated using CSTtrade microwave...
