Wide Beam Tapered Slot Antenna for Wide Angle Scanning Phased Array Antenna

Abstract

Abstract-Design and development of a low profile, compact, wide beam and wide band printed double layered exponentially tapered slot antenna (DTSA) with a coplanar waveguide (CPW) feed meant for wide scan active phased array antenna in X-band has been presented. DTSA satisfies the requirements on the maximum reflection coefficient of Γ ≤ −10 dB for ±60 • and ±45 • scan from broadside in H-and Eplanes, respectively with a moderate gain of 4-7 dBi. Realized antenna has shown a symmetric pattern together with moderately high gain, low cross-polarization and 3 dB beam width better than ±60 • and ±45 • in H-and E-planes, respectively. The designed structure is expected to find applications in mounting platforms with limited RF real estate available to it like in military aircrafts, owing to its easy integration with the uni-planar monolithic millimeter-wave integrated circuits.

Spidron fractal tapered slot antenna for dual-band radar applications

“…However, most of the recent designs for TSAs have been carried out for ultra-broadband applications. [18][19][20] In this paper, we propose a compact dual-band TSA utilizing a Spidron fractal for radar applications in the S and X bands. The Spidron fractal TSA is fed by a simple microstrip-to-slotline transition.…”

Planar High Gain Dielectric Loaded Exponentially Tapered Slot Antenna for Millimeter Wave Wireless Communications

“…On both places, a reflection of the traveling wave is likely to occur. Therefore, smoother taper in the neck minimizes the reflection there [25,26]. This can be achieved with higher value of 'a'.…”
