﻿ @book{meinke_antennas_1968, series = {Final scientific rept. 1 May 66-30 Nov 68}, title = {Antennas Integrated with Transistors and Varactor Diodes}, abstract = {Part 1 deals with transistorized receiving antennas. Definitions of gain, directivity, effective area, noise temperature, noise figure, and sensitivity are given. Active and passive antennas are compared concerning their noise behaviour. The difference between noise match and power match is described. Definitions and measuring methods for bandwidth, selectivity, intermodulation, and crossmodulation in active antennas are given. Part 2 deals with transistorized transmitting antennas. Transistor power gain and power match to the antenna are discussed. Measurements of the radiation of harmonics are described. Part 3 deals with tunable antennas. Examples of antennas tuned with transistors below 30 {MHz} and tuned with varactor diodes at Frequencies abov 30 {MHz} are given. Part 4 shows a semidirective antenna with adjustable pattern for vertical and horizontal scanning.}, publisher = {Institut für Hochfrequenztechnik der Technischen Hochschule München}, author = {Meinke, Hans H. and Flachenecker, Gerhard and Landstorfer, Friedrich M. and Lindenmeier, Heinz K.}, month = dec, year = {1968} }, @article{landstorfer_antennenmesraum_1968, title = {Antennenmeßraum im Bereich von 1 {MHz} bis 500 {MHz}}, volume = {21}, journal = {Nachrichtentechnische Zeitschrift}, author = {Landstorfer, Friedrich M.}, month = apr, year = {1968}, pages = {186--190} }, @inproceedings{meinke_noise_1968, address = {Boston, {MA}, {USA}}, title = {Noise and Bandwidth Limitations with Transistorized Antennas}, volume = {6}, doi = {10.1109/APS.1968.1150608}, booktitle = {Antennas and Propagation Society International Symposium}, author = {Meinke, Hans H. and Landstorfer, Friedrich M.}, month = sep, year = {1968}, pages = {245--246} }
