摘要: A compact printed planar antenna fed asymmetrically by a 50 Ω microstrip line is presented. This novel structural configuration derived from conventional rectangular monopole, introducing feed-line asymmetry to offer octave band end-fire radiation patterns. ground plane of considerably small length and modified in shape with two symmetrical bevel slots on the upper edge, illustrate significant improvement input impedance matching over operating bandwidth. The influence patch thickness dielectric substrate gain explored numerically. By linearly tapering patch, observed. Both numerical experimental reflection coefficient results confirm that proposed presents an bandwidth 94% for coefficients less than -10 dB. measured present optimum 11.8 dBi stable unidirectional has wide bandwidth, size reasonably high gain, suitable various broadband applications including point-to-point communication. simple structure very few design parameters.
