Design and Investigations of Multiband Microstrip Patch Antenna for Wireless Applications

Abstract

Novel design for compact Multiband Microstrip Patch Antenna (MMSPA) is proposed. Antenna has rectangular-shaped patch and V and U slots are etched on patch and ring slot on ground plane which is covering patch from back along with line separation in ground plane. By connecting and disconnecting separation, it gives another design that also presents multiband operation along with frequency tuning capability. Physical dimension of proposed antenna is 0.1833 λ0 X0.147 λ0 in mm where λ0 is the wavelength (at free space) of the first resonant frequency 2.4 GHz. Inset feed microstrip line is used. MMSPA is simulated on CST software. Antenna resonates at 2.4, 4.1, and 7.98 GHz when separation cut is present at ground and antenna resonates at 2.5, 7.7, and 10.5 GHz when separation cut is connected at back of feed line (ground plane) S11 of −21.3, −13.7 and −20 and −13.6, −16.5 and −20.2 dB, respectively. Proposed antenna may be utilized for IEEE 802.15.1 (2.402–2.480 GHz band), TD-LTE 2300/2500 (2.2–2.5 GHz), ITU#10 band, and X-Band Satellite Communication Service (XSCS) applications.
