antenna employing a nonparasitic grounded reflector is presented.
This fan-beam antenna is achieved using a six-element conventional
planar monopole array antenna and feed network, which
together produce sidelobes at 26 dB. Dolph–Tschebyscheff
distribution is employed, and a broadband array feed network is
designed to satisfy beneficial input impedance bandwidth requirements
in the frequency range 1.7–2.2 GHz. Therefore, this array
covers applications of GSM-DCS2, DECT, and 3G. Combining
planar monopole antenna as an array with nonparasitic grounded
reflector allows an advantageous fan beam pattern to be generated.
H-plane 3-dB beamwidths are controllable using grounded
reflector height. In addition, the results are compared with and
without reflector array antenna.
