Advancement in Designing of Wideband Horn Antenna
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 4
Abstract
A Dual Ridge Horn Antenna operating in frequency range of 4-17 GHz is designed using equation based exponential tapered part varies the impedance of the guide from 50 © at the feeding point (double-ridged rectangular waveguide) to 377 © at the aperture of thenantenna. Designed Horn Antenna has a total length of 43.375 mm which means it is very small in size and weight. An N- type coaxial line to rectangular double-ridged waveguide transition is introduced for coaxial feeding of the designed antenna. Major modifications are imposed on Back Cavity, exponential taper and to design antenna as small as possible. The proposed antenna is simulated with commercially available packages such as Ansoft HFSS. Microwave Studio for the given operating frequency range. The antenna gives decent gain of about 4 dB to 25 dB over operating range while delivering 13 GHz bandwidth
