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.

International Journal of Electronics Letters, 2018
In this paper, a compact microstrip fed UWB monopole antenna for dual band applications is proposed and investigated. The base of the proposed antenna is a rectangular shaped radiator. The radiator of an antenna occupies a small area of only 10.2 × 7.6 mm 2 (0.081λ 0 × 0.06λ 0) that covers the UWB frequency range. To create a dual band antenna by etching a quarter wavelength resonator, loop strips into radiator is designed which generates the notch band characteristic. The proposed structure consists of rectangular patch shape at centre with two symmetrical loop strips. Dual band antenna is designed on FR-4 substrate whose dielectric constant is 4.4, tangent loss 0.02 and thickness 1.59 mm. The overall size of proposed antenna is 15 mm × 15 mm (0.12λ 0 × 0.12λ 0). 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).

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.
