Resumos Cadastrados
Resumo Inglês:
An L-strip proximity coupled circular microstrip
antenna is proposed. The structure is investigated using circuit
theoretic approach and simulated using IE3D simulation software.
The patch is designed on a thick substrate of thickness of 11 mm for
a design frequency of 3.74 GHz and provides ultra wide band
operation. The numerical results for input impedance, VSWR,
radiation pattern, efficiency and gain are presented. Bandwidth is
found to be dependent on length of horizontal part of L-strip. A
bandwidth of 69.52% is achieved (for VSWR≤2) for y0=0.112λ0 and
h2=0.097λ0. The beam of antenna rotates with operating frequency.
