  Blazars host the most powerful persistent relativistic conical jet -- a
highly collimated anisotropic flow of material/plasma. Motivated by this, we
explore the blazar's broadband spectral energy distribution (SED) in an
anisotropic flow of plasma which emits via synchrotron and inverse Compton (IC)
mechanism. The flow is conical with two velocity components: a highly
relativistic flow component along the jet axis and a random perpendicular
component with average random Lorentz factor $\langle \gamma^{ran} \rangle$
$<<$ than the average component along the jet axis $\langle \gamma \rangle$.
Assuming a broken power-law electron population, we calculated the broadband
SED using synchrotron and IC processes assuming a cylindrical (of radius R and
length L) emission region. For the IC process, we used Monte Carlo approach. We
found that such anisotropic flow can reproduce blazars broadband emission as
well as general short and high amplitude variability, indicating that spectral
and temporal variability are not sufficient to distinguish among existing
models. We demonstrate this by reproducing SEDs of FSRQ 3C 454.3 and three BL
Lacs objects OJ 287, S5 0716+714, PKS 2155-304. Our formalism and set-up also
allow us to investigate the effect of the geometry and dimension of emission
region on observed broadband spectra. We found that the SEDs of low synchrotron
peak (LSP) blazar can be explained by considering only SSC (synchrotron
self-Compton) if R/L ($<$ 0.01), broadly mimicking a spine-sheath geometry. In
general, the degeneracy between non-thermal particle number density and length
of the emission region (L) allow us to reproduce any variability in terms of
particle number density.
