A new Chebyshev tapered series-fed printed dipole antenna comprising rhombus radiators at L band for SSR application, is investigated. Effects of vital parameters on antenna performance and some other details are analyzed and discussed as well. The proposed antenna, designed on standard RO5880 substrate with 0.787 mm thickness. On the basis of careful design and optimization, antenna possesses an...
A new wideband antenna operating at VHF band for communication systems is designed and implemented in this paper. The antenna at first consists of two quad antenna (Biquad). Gain of around 5 dB of this section are demonstrated; narrower beam widths and a further increase of gain is achieved using a reflector. For further increase of gain and beam width in azimuth plane, some passive elements are added...
This paper presents analysis and design of a new planar slot array antenna with reduced back radiation for secondary surveillance Radar (SSR) application. Feed network for sum and difference beams with hybrid phase shifter and branch line coupler are implemented. A backfill antenna is designed and used to improve coverage of difference pattern in back of antenna. The effects of vital parameters on...
