Abstract

A novel compact patch antenna with Defected Ground structure (DGS) operating for Wireless applications is proposed and investigated. This proposed antenna generates four separate resonances to cover 3.271 GHz (WiMax), 4.92 GHz (WiFi), 6.35 GHz (Space applications) and 11.04 GHz (Fixed Satellite applications) while maintaining overall compact size of 32 × 32 × 1.6 mm³ using an FR-4 substrate commonly available with a permittivity of ε_r = 4.4. The proposed microstrip patch antenna (MSPA) consists of a square radiator in which a Log Periodic slot is etched out along with square defects on ground surface and a microstrip feed line. The log periodic slot with DGS modifies the total current path thereby making the antenna operate at five useful bands. Structure displays the impedance bandwidth of 8.34% (3.10-3.37 GHz), 2.00% (4.88-4.98 GHz), 14.68% (6.27-7.194 GHz), and 5.41% (10.79-11.39 GHz) with gains 3.25 dB, 0.85 dB, 5.65 dB and 4.47 dB respectively. The antenna performance is analyzed using numerous parametric optimization studies, field distributions, and currents. Excellent agreement is obtained between measured and simulated results.
