- Abstract
This paper presents a compact design of a conformal log.-periodic four arm antenna with feeding network integrated on a single conical MID. The antenna structure incorporates two decoupled, predominantly linearly polarized radiators. Both radiators provide an input matching of better than 8 dB over a frequency range from 4.5GHz to 11GHz. The antenna radiation patterns are characterized by a front-to-back ratio between 4 dB - 7.5 dB and a maximum gain of 5 dBi between 5GHz and 7GHz in main beam direction. The pattern correlation coefficients below 0.3 confirm broadband diversity properties sufficient for MIMO applications. The overall antenna diameter and height are 50mm and 24mm respectively. It could therefore be used as a surface mounted or ceiling antenna in buildings, vehicles or aircrafts for communication systems.
