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.

CO-AXIAL FED MICROSTRIP RECTANGULAR PATCH ANTENNA DESIGN FOR BLUETOOTH APPLICATION
A design procedure for Microstrip rectangular patch antenna for Bluetooth application is presented. In Bluetooth open wireless technology important constraints are size and installation of the antenna. In this paper the proposed antenna is designed using transmission line model and can create resonance at 2.45 GHz with in Bluetooth frequency range 2400-2485 MHz. Coaxial feed technique is used to excite the patch even though microstrip inset feed technique is present because of low radiation and ease of installation. Placement of co axial feed for this patch is taken almost one third of length from virtual ground line i.e., at the center line of the patch which is along the width lines and can creates resonance at 2.45 GHz with minimum reflection coefficient (s 11) at this feed position. Fabrication is done using photolithographic technique and is tested with Agilent Network Analyzer to measure VSWR and S 11 parameters. S-parameters are used to measure the antenna performance and shown that S 11 value is low at resonant frequency. Variation of input impedance as function of frequency is also presented using Smith Chart. Radiation patterns are drawn both in E-plane, H-plane in anechoic chamber and parameters like gain, beam width (both E and H planes) are measured. Designed antenna is simulated on FR4 substrate with loss tangent tanδ=0.02 using Agilent Advance Design System (ADS) software. Simulation and measurement results are compared and discussed.
