MM-Wave Integrated Antennas on Low Cost MCM-D Substrates
This paper discusses the EM modelling and practical design of milimeter wave microstrip patch elements in the frequency range of 80GHz on low cost MCM-D substrates. The critical parameters of milimeter design such as losses, bandwidth and the influence of process tolerances on antenna performance are discussed.
متن کاملLow Loss mm-Wave Monolithic SP4Ts
Many of the emerging broadband wireless access systems operate at mm-wave frequencies where large allocations of spectrum are available. GaAs Monolithic Microwave Integrated Circuits (MMICs) offer a means of realising low cost, high performance, high volume, reproducible mm-wave components. This paper details two Single Pole 4 Throw (SP4T) switch MMICs covering 24 to 34GHz and 34 to 45GHz. The ...
متن کاملLow-cost chaotic radar design
An approach for creating a low-cost Chaos Pulsed-Doppler Radar is presented. The objective of this effort is to develop a practical realization of a Chaotic Radar with performance advantages over other approaches. Many groups [2], [3] have proposed that Chaotic Waveforms are an effective radar signal generator due to: the relatively low cost of producing complex wideband waveforms and the diffi...
متن کاملA Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor
Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
متن کاملDistributed Elements and MM-Wave Characterization of Low Cost MCM-D Substrates
Future telecommunication aplications will shift more and more to the use of higher frequncies. Multichip Modules (MCMs) and MCM technologies are very close to microand milimeter-wave systems like transmitter/receivr (T/R) for radars and communication modules for wireless infrastructure links. There are various stringent requirements for MCMs in the frequency range of 1 to 100GHz but one of the ...
