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^o and ±45^o scan from broadside in H- and E-planes, 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^o and ±45^o 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.
