Side Lobe Level Reduction of Any Type of Linear Equally Spaced Array Using the Method of Convolution
In most applications of antenna arrays, side lobe levels (SLLs) are commonly unwanted.
Especially, the first side lobe level which determines maximum SLL is the main source of electromagnetic
interference (EMI), and hence, it should...
Development a new wideband substrate integrated waveguide H-plane horn antenna loaded with periodically diamond patches
>impedance bandwidth, which covers from 20.8 GHz to 26.15 GHz with stable end-fire radiation patterns,
while Side Lobe Level -SLL- is lower than 10 dB over the operating bandwidth....
Modified SIW H-Plane Horn Antenna with Improved Gain Using Thin Substrate
distribution
along radiating aperture. Also, to reduce Side Lobe Level (SLL) of
the antenna and to enhance gain, a dielectric slab and a row of
patches are placed at the front of the aperture. The proposed SIW
horn antenna...
Thinned Array Inspired Quasi-Uniform Leaky-Wave Antenna With Low Side-Lobe Level
is designed using a systematic method based on the thinned array theory in order to achieve a low side-lobe level (SLL). The designed antenna radiates at center frequency of 10 GHz at θ=60∘ with the SLL of about –20 dB. The proposed antenna scans a part...
optimization of array factor in linear array by using modified genetic algorythm
The array factor (sidelobe level, SLL) of a linear array is optimized using modified
continuous genetic algorithms in this work. The amplitudes and phases of the currents as well as the
separation of the antennas are all taken...
