Design of Dual -Band Coax Patch Antenna for GSM and Bluetooth Applications
Ogunlade Michael Adegoke  | Charles Okanda Nyatega 
Abstract: This paper proposes the design of dual-band coax patch antenna for GSM and Bluetooth applications. The proposed antenna is suggested to be used in a mobile phone handset that covers dual frequency bands which include GSM1900 (1850-1990MHz) and Bluetooth (2400-2483.5MHz). The simulation of the antenna is performed using a High Frequency Structure Simulator (HFSS) software. Analysis for return loss, VSWR, gain and radiation pattern were carried out. The proposed antenna shows return loss of -29dB at 1.9GHz and -30dB at 2.4GHz which implies good results. The impedance matching is good at the desired frequencies with VSWR < 2 respectively. The overall simulation results shows that the antenna worked well at the desired dual frequencies and hence making the antenna suitable for use in both GSM and Bluetooth applications.
