This paper presents a wideband or high gain 4x4 array operating in k-band. The unit cell of this array is a rectangular patch antenna in a stacked configuration. Four rectangular patches are passively excited by an additional rectangular patch located underneath. The latter is excited by a substrate integrated waveguide (SIW) through an aperture etched on the ground plane. By moving the relative position, and therefore the overlapped area, between the passive patches and the active one, a wideband or a high gain behavior can be obtained, maintaining the same layout. The proposed array achieves the impedance bandwidth of 12.55% with a gain of 22 dBi for the wideband case. In the high gain case, the impedance bandwidth is 5.5% with a gain of 24 dBi.

<p>Antennas are long used for communication of data since a century and their usage has been diversified over the past two decades and the antennas also entered the domain of medical fields. A rectangular microstrip patch antenna has been designed on a substrate integrated waveguide with frequency selective surface which is in the shape of a square. The design of this antenna with SIW are done by using CST on a low cost FR4 substrate where є<sub>r</sub> =4.4, h=1.58 mm and tan δ=0.0035. The SIW structure merit is utilized on the traditional FSS is simulated and verified by using CST.</p>

“…In the year 2014 ISRO have launched GSAT-14, for providing a platform for new experiments with two beacons operating at 20.2GHz and 30.5GHz [6] [7]. A micro strip array antenna at Ka-band consisting of 4×1 and 4×2 elements with a gain of 12.43 dB and 13.72dB at 35GHz with return loss of -19.20dB and -40.01dB has been reported in [8]. In [9] the phased patch array antenna at Ka-band with single element gain of 6.3 dB and 4×4 elements have gain of 15.6dB with a beam steering implementation is observed.…”

The design and analysis of single double (1×2) and four (1×4) element linear rectangular micro strip array antennas is done to achieve high gain and directivity. The operating frequency of the proposed array antenna is Ka-band, 20.2GHz which is a Beacon frequency of GSAT-14 launched by ISRO.The substrate material used is common for the single, double (1×2) and four (1×4) i.e. FR4 with a thickness of 0.8mm and the dielectric constant is 4.4. The antenna elements are placed uniform at a same distance. The feeding network used here is a parallel or corporate feed network. The power splitting and impedance matching is done using RF Wilkinson power divider. The entire proposed micro strip phased array antenna is evaluated using HFSS software tool.
