Wide - Band Test Antennas

As part of an indoor mutt/path measurement system, discone antennas featuring simple N~onnector feed systems have bHn designed for the 1.0 to 2.0 GHz band. Extensive experimentation reveals that excellent performance (VSWR < 15:1 across the band) can be obtained with a simple "snap-on" feed/mount method, and that VSWR is most sensitive to the diameter of the disc feed conductor. Per· formance d...

Slot Cut Ultra Wide Band Antennas

The ultra wide band antennas are required in applications where larger bandwidth for the transmitting signal is needed. They cover wide bandwidth in the range from 500 MHz to the frequencies above 8000 MHz. In this paper, a review of various techniques to realize ultra wide band microstrip antennas (MSA) is presented. They are realized by using different techniques like basic planar monopole an...

Design Aspects of PrintedMonopole Antennas for Ultra-Wide Band Applications

This paper presents the design equations for lower band-edge frequency for all the regular shapes of printed monopole antennas with various feed positions. The length of the feed transmission line is a critical design parameter of these monopole antennas. Design curves for the length of the feed transmission line for various lower band-edge frequencies for all these regular shaped monopoles hav...

A Vhf-uhf Television Turret Tuner

ITH the advent of ultra-high-frequency television and the subsequent allocation of specific UHF channels, the need for a VHF-UHF television tuner becomes apparent. This tuner should ideally make the maximum use of the same components on VHF and UHF, so that there would be a minimum duplication of parts. This design should be one which would give optimum performance and still be easy to fabricat...
