Abstract
The presented manuscript represents a miniaturized microstrip patch antenna with frequency and pattern reconfigurability. Three modes are analyzed based upon switching actions of two PIN diodes to achieve tunability. Low profile material FR-4 is used for the fabrication. The analysis is carried out in terms of tunability, reflectance response, resonance frequency, electric field, and bandwidth. The proposed structure provides tunability for the two bands. The proposed design provides the maximum tunability of 340 MHz, the bandwidth of 700 MHz, reflectance response of - 40.38 dB, an electric field of 4234.9 V/m, and beam tilting capability of 30 degrees, - 40 degrees, + 35 degrees, - 90 degrees, and 120 degrees. Simulation and fabrication are carried out for the verification. The optimization of design is carried out by varying the dimensions of the three parameters. The comparison is also carried with previously published work. The proposed design can be used for multiband applications in the S and C bands.
