Rectangular Microstrip Antenna

RCS is very significant to confirm data for target designation. The targets signature is different, because every target has own signature, and this specific signature is utilized to recognize the type of structure which will be tested. The monostatic radar utilizes one antenna on the body for reducing the scattering of signals for given polarization and receive and transmit in this type in the same location. Microstrip patch antenna is widely used in microwave systems, especially for space applications. In this paper, rectangular microstrip antenna in c-band frequency is designed and simulated as a target to calculate monostatic RCS area using CST software 2019. The strip antenna is simulated and modeled for different target angles (0, 45, 60and 90) degree. The monostatic radar cross section is simulated at 8GHz with incident angles from 0-180 degree. The best RCS of rectangular patch antenna is about -31m2 at the incident angle θ=60o.

This paper proposes a novel wideband to concurrent tri-band frequency reconfigurable microstrip antenna. The frequency reconfiguration is achieved by using a pair of PIN diodes in the antenna feed line to switch the antenna either in wideband mode or in concurrent tri-band mode. In order to improve the bandwidth and gain of the antenna for wideband operation, the properties of J-K inverter and split ring resonators are exploited. To demonstrate the versatility of this concept a prototype is fabricated and tested here. The tested results in wideband mode shows that the proposed antenna operates from 3.58 to –3.82 GHz, which is 4.08 times larger than the bandwidth of a simple microstrip patch antenna. In the concurrent tri-band mode frequency tuning is done by microstrip open stub at 1.5 GHz, 1.9 GHz, and 3.5 GHz. Gain of the proposed antenna is better than 2.7 dB in wideband mode and 2.7 dB in concurrent tri-band mode.

The objective of the paper is to design and investigate a rectangular microstrip antenna that covers the band from 2.4 to 3.6 GHz. The proposition consolidates investigation of fundamentals of microstrip patch antenna. A progression of simulation in Ansoft HFSS (High Frequency System Simulation) has been carried out to discover the dual operating frequency. The qualities of the patch antenna rely on its different geometrical parameters. The investigation is carried in terms of two prime factors: Return loss and radiation pattern.

Rectangular Microstrip Antenna

In this work, a simulated study was carried out for designing a novel spiral rectangular patch of microstrip antenna that is used in ultra-wideband applications by using a high frequency structure simulator software (HFSS). A substrate with dielectric constant of 4.4 and height 2.10 mm (commercial substrate height available is about 0.8-1.575 mm) has been used for the design of the proposed antenna. The design basis for enhancing bandwidth in the frequency range 6.63 - 10.93 GHz is based on increasing the edge areas that positively affect the antenna's efficiency. This design makes the designed antenna cost less by reducing the area of the patch. It has been noticed that the bandwidth of the antenna under this study is increasing to 4.30 GHz or 61% compared with 3.6% for the standard rectangular microstrip antenna with the same dimensions of the proposed antenna. The antenna also maintains the voltage standing wave ratio of 1.09 at resonant frequency 7.07 GHz, return loss -27.07 dB, and the amount of impedance in real and imaginary parts 51.5Ω and 3.3Ω, respectively.
