Design of ultra-wideband antenna

Abstract

The paper mainly introduces design and realization of sending and taking over antenna based on a kind of Ultra-widehand MIR movement sensor circuit. In the paper, four kind of antennas are designed, including plane-helix antenna, wave-guide antenna, exponent antenna and symmetrical dipole antenna. Through the examinations on four kind of antennas, the result testifies that the symmetrical dipole antenna is fittest for MIR among them. Therefore, the paper briefly gives the elementary case of symmetrical dipole antenna and mainly introduces the design, realization and test of it.
