  ABSTRACT: The development of a low profile, lightweight, broadband spiral antenna for airborne applications is described. The use of an electromagnetic band gap substrate with loads as reflector for an Archimedean spiral antenna is proposed. A method based on a transmission line model is presented to design this loaded electromagnetic band gap substrate. Simulation and measurements results demonstrate the applicability of the concept. A good impedance matching as well as a good circular polarisation are achieved over a 10:1 frequency bandwidth. Finally, thickness and weight of this new antenna are greatly reduced and their performances are better compared with a conventional spiral antenna with unidirectional beam

  ABSTRACT: This paper presents the design of a low profile, lightweight, broadband spiral antenna for airborne applications. A thin modified electromagnetic band gap substrate with load is used as reflector for an Archimedean spiral antenna. This new loaded electromagnetic band gap (LEBG) substrates has very wideband radiation characteristics and has an easier realization than the mushroom-like surface. The conception of the antenna has been validated by measurements. Thickness and weight of this new antenna is greatly reduced and radiation characteristics are better compared to a conventional spiral antenna with unidirectional beam.

• Conference Proceeding: Archimedean microstrip spiral antenna loaded by chip resistors inside substrate

  ABSTRACT: An ultra-wide-band (UWB) microstrip spiral antenna is proposed. The antenna is resistively loaded inside the substrate to maintain a good circular polarization on the bandwidth. The main performances are a very thin thickness (λ/100 at the lowest operating frequency), good impedance matching and right hand circularly polarized patterns over a 9:1 bandwidth.
