摘要: The radiation characteristics of grid antennas are investigated. A balanced feed array antenna (a GA), which radiates a linearly polarized wave and is used as reference antenna, has half-power beamwidth (HPBW) 19° in the ϕ = 0° plane 18° 90° plane. gain GA calculated to be 19.1 dBi. It shown that circularly obtained when C-figured elements added GA. rotation angle for right-hand ϕrot 135°, while left-hand 45°. HPBW CGA almost same those In addition CGA, unbalanced also analyzed. found Similarly, HPBWs same. axial ratio at center frequency 0.2 dB 17.3 dBi, respectively. bandwidths both approximately 8%. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 85(1): 58–68, 2002
