Design and Analysis of M-Shaped Monopole Antenna for Bluetooth communications

The M-shaped monopole antenna is an antenna that has a reduced size for bluetooth and wireless communication. It is an integrated, portable, wideband antenna with a gain of 2dBi-5dBi and a frequency range of 0. SGHZ-2.45GHZ. A 0. 4mm substrate height and 4.4 relative dielectric constant was found to have a VSWR <3:1. The T-shaped groundplane is incorporated into the design at the price of bandwidth in order to further minimize size, which was chosen to represent the dimensions of a normal mobile phone. Two trapezoidal sections, a triangular part, and a rectangular section are combined to form the M shape of the Mshaped antenna. A 50$\Omega$ feed line can be used as the impedance bandwidth is huge. Over the operational band, the radiation pattern is comparatively steady, producing an omnidirectional pattern. The antenna is a desired component for usage in a variety of mobile communication systems due to its small size and broad bandwidth.
