Abstract Antenna studies on various wireless communication systems have been carried out by many academics. In this research, the omnidirectional microstrip patch antenna (MPA) is proposed, manufactured, and tested. The operating bandwidth of the antenna is quite suitable for the different applications. The proposed antenna fabricated on the flame retardant (FR-4) substrate with a volume of 75.85 × 57.23 × 1.59 mm3. Computer simulation technology (CST) studio used to design and simulate. Experimental results show that the return loss (RL), bandwidth (BW), voltage standing wave ratio (VSWR) and input impedance (Zin ) are -25.26 dB, 61 MHz, 1.12 and 54.46 Ω, respectively. The antenna operates at 2.42 GHz (from 2.39 to 2.45 GHz), which has good performance in the Wi-Fi, Bluetooth, and ZigBee communications.

This is the first report on novel mushroom-type electromagnetic band gap (EBG) structures, consisting of fractal periodic elements, used for enhancing the gain of microstrip patch antennas. Using CST Microwave studio the performance of rectangular patch antenna has been examined on proposed fractal EBG substrates. It is found that fractal EBGs are more effective in suppressing surface wave thus resulting in higher gain. The gain of rectangular patch has been improved from 6.88 to 10.67 dBi. The proposed fractal EBG will open new avenues for the design and development of variety of high-frequency components and devices with enhanced performance.

Variables are utilized to improve the antenna’s simulation results are as position, space, length, and width of different mirror images T and I shaped antenna slots. The measured results from the simulated design show that the designed construction resonates at various closely separated frequencies that are within the frequency band allotment for wireless applications. At resonance frequencies of 2GHz to 3GHz, the bandwidth and return loss are significantly enhanced.

Measured Sensitivity

A slot-loaded microstrip patch sensor antenna is proposed to enhance sensitivity in measuring the permittivity of planar materials. A thin rectangular slot was etched along the radiating edge of a rectangular patch antenna fed by a microstrip transmission line. Two resonant frequencies were created at a lower frequency compared to the single resonant frequency of a conventional ordinary patch antenna. The sensitivity of the proposed slot-loaded patch antenna was measured by the shift in the resonant frequency of the input reflection coefficient when the planar dielectric superstrate was placed above the patch, and was compared with that of a conventional patch antenna without the slot. The two antennas were designed and fabricated on a 0.76 mm-thick RF-35 substrate for the first resonant frequency to resonate at 2.5 GHz under unloaded conditions. Five different standard dielectric samples with dielectric constants ranging from 2.17 to 10.2 were tested for sensitivity comparison. The experiment results showed that the measured sensitivity of the proposed patch antenna were 3.54 to 4.53 times higher, compared to a conventional patch antenna, for the five samples.

Imaging Application

This paper present the brief view to design of a microstrip rectangular patch antenna. Microstrip patch antennas are used because of configuration such as low profile, conformal, light weight, and easy fabrication. The linear polarization and circularly polarization of microstrip patch antennas have attracted more attention recently. These antennas are significant due to their ability to improve the benefits of microwave imaging application. The Federal Communication Commission (FCC) has approved the frequency limit for narrowband and wideband antenna. One of the advantage of the narrow band technology is the design of feasible compact conformal antennas. Therefore a compact miniaturized microstrip rectangular patch antenna has been proposed to design for microwave imaging application. The miniaturization of microstrip patch antenna has been done to obtain the better narrow bandwidth, return loss and Voltage Standing Wave Ratio (VSWR). Ultra Wide Band (UWB) is achieved by using certain techniques which is used for expansion of bandwidth. The rectangular patch antenna with a 50Ωmicrostrip feed is fabricated on the FR4 substrate.
