TELKOMNIKA, 2023
The most researched and examined aspect of the communication system is the wireless connection. Without learning how to operate and use different types of antennas, your knowledge is incomplete. Microstrip patch antenna research has advanced significantly in recent years. When compared to standard antennas, microstrip patch antennas provide additional advantages and opportunities. It is of low volume, light weight, low cost, low appearance, compact and easy to manufacture. This study investigates the differences between rectangular and circular patch antennas. For Bluetooth applications, the center frequency of 2.4 GHz was chosen as the optimal resonant frequency. On a flame retardant (FR-4) epoxy substrate, the antenna dielectric constant is 4.4. Above the ground the base rises 3.6 mm. For the simulation process, high frequency simulation software (HFSS 15) is used as the program design. Antennas 1×1, 1×2, and 1×4 are designed for both circular and rectangular antennas. A comparison was made for both types of antennas and voltage standing wave ratio (VSWR), return losses, gain, directivity and half power beam width (HPBW) were found, and the feature of the rectangular antenna was shown.

The 10-dB impedance bandwidth of the antenna is 520 MHz (2.3-2.82 GHz) and 5.51 GHz (3.8-9.31 GHz). Also same configuration antenna is designed on Roger RT/Duroid substrate whose dielectric constant is 2.2, loss tangent 0.0009 and thickness 30 mil (0.762 mm). The simulated result is approximately same as FR-4. It covers the LTE, ISM, WLAN, WiMAX, X band satellite communication and ITU bands for wireless communications. To verify the proposed antenna design and response, a prototype has been fabricated on FR-4 and parameters are measured. The measured response validates the simulated response.
