Multielement UWB receiving antenna
4th International Conference on Antenna Theory and Techniques (Cat. No.03EX699), 2004The paper presents the results of simulation of a multielement receiving loop antenna intended to receive ultrawideband (UWB) pulse electromagnetic signals. The dependence of the current amplitude at its output on the antenna dimensions has been obtained.

The basic theory of a receiving antenna is presented in sufficient detail to permit the calculation of the voltage across the load of an optimally designed TV antenna circuit. The rms load voltage is given by VL=λH(30RrD)1/2, where λ is the wavelength of the incident radiation, H is the rms value of the magnetic field intensity, Rr is the radiation ...

The modal solution to a biconical receiving antenna with arbitrary arm angles and lengths is presented in the form of sums over special functions; sums which are exact in the sense that no electromagnetic approximations are made. The antenna load is confined within a sphere of small radius centered at the apices of the cones. The analytical formulation

Adaptive Antenna for Handheld GPS Receivers
Navigation, 2010An adaptive antenna for handheld GPS receivers is presented. The antenna has a small aperture, small volume, and is lightweight. The antenna uses four spiral elements to provide broadband satellite coverage and can also be used in conjunction with a space-time adaptive processor (STAP) for interference suppression.

A simple DBS receiving antenna-a tripole antenna
Digest on Antennas and Propagation Society International Symposium, 2003Results of an investigation of a tripole antenna for DBS (direct broadcast satellite) systems are presented. A tripole of a=1.25 mm, h=50 mm, g=18.75 mm, and d=18.75 mm operating at 12 GHz is chosen as the representative antenna. The variation in the input admittances of the representative tripole with respect to the change in its driving point is ...

Multi-GNSS Receiver Antenna Calibration
2020Global Navigation Satellite Systems (GNSS) are not only widely used for precise positioning, navigation and timing but also for establishing of terrestrial reference frames for geospatial applications, such as land and water management. The quality of GNSS carrier phase measurements depends on the knowledge about the location of the exact electrical ...

High gain and low noise characteristics are strongly required for DBS receiving antennas; reflector antennas have been the most popular. Recently, various kinds of flat array antennas are proposed and used as commercial products. This paper describes the state of the art of DBS receiving flat arrays.
