Acoustic Models of Radio Antennas
Proceedings of the IRE, 1941The large number of independent variables in antenna arrays make it advisable to develop means for rapidly surveying the field patterns which may be obtained. The advantages in the use of acoustic models for this purpose are shown. Two analogous acoustic antennas are developed, one for the measurement of fields at a distance and the other for fields ...

Packset radio antenna measurements
IRE International Convention Record, 2005Packset radio antennas in the HF and VHF ranges have traditionally presented severe matching problems due to the dependence of antenna parameters on position, surroundings and operator. The advent of high power (20-40W) packsets tunable over the entire HF and VHF range have made better antenna matching desirable. A novel antenna measurement test set is

Antennas for digital radio broadcast
Ninth International Conference on Antennas and Propagation (ICAP), 1995The Digital Radio Broadcast is reviewed briefly and the gain, polarization and other electrical requirements of mobile antennas for direct satellite signal reception, or terrestrial broadcast signals is discussed. Low profile and low cost antenna candidates in the form of multifilar helices and microstrip type radiators are introduced and compared. >

ANTENNA DEVICE FOR RADIO TELEPHONES
2007The aim of the invention is to technically improve an antenna device for radio telephones, based on a printed circuit board antenna or a strip conductor antenna, in such a way that it is economical and simple to produce and has a high efficiency, but nevertheless ensures that the user of the radio telephone is less exposed to the effects of ...

Antenna Combined with Radio Tuner
SAE Technical Paper Series, 1988<div class="htmlview paragraph">Since the introduction of the car radio, reception quality has been less than perfect. Currently, audio reception is accomplished with a co-axial cable between the antenna and radio tuner. Unfortunately this system looses transmission in various ways.</div> <div class="htmlview paragraph">Today we will ...

Antennas for Mobile Radio Systems
2004Transmission and reception of radio waves require antennas. In providing gateways to transmission and reception of radio signals, antennas play important roles both at the base station and mobile terminal. Though, higher transmit power and greater receiver sensitivity can improve radio link quality and reliability, the regulatory authorities place a ...
