![]() In this paper a dual band (2.4 GHz and 5.4 GHz) microstrip patch antenna is designed and compared using a conventional and artificial ground planes for Wi-Fi and WLAN applications. It has been observed that the practical results obtained by testing the fabricated antenna using Network analyser E5071C closely matches with the theoretical results obtained by simulating the antenna design in CST MWS 2010. The simulated antenna has been fabricated and tested successfully using network analyser E5071C with anechoic chamber. The antenna has bandwidth of 5.74 GHz and VSWR less than 2. The designed MPA is suitable to be used for bluetooth, International Mobile Telecommunication (IMT), WLAN, WiMAX and C-band (satellite) applications. ![]() The antenna has bandwidth of 5.74 GHz and resonant at 2.33 GHz, 4.58 GHz, 5.85 GHz and 7.15 GHz with corresponding return loss of -33.72 dB, -37.1 dB, -36.50 dB and -18.14 dB, respectively. The antenna has been designed and simulated using CST Microwave Studio (2010). The antenna performance has been analyzed in terms of antenna parameters such as return loss (dB), bandwidth (GHz), gain (dB), directivity (dBi), antenna impedance (ohms) and VSWR. A notch has been added in feed line to improve return loss and antenna bandwidth. The feed line has to be of suitable width so as to match the antenna impedance with the port impedance (50 ohms). ![]() partially reduced slotted ground plane has been employed to enhance the antenna bandwidth. A circular slot has been drilled in substrate to improve the return loss. ![]() The antenna has been designed using slotted substrate of FR4 material having dielectric constant of 4.4 with slotted radiating patch and a defected ground plane. Abstract: In this paper, a multi resonant slotted Micro Strip Patch Antenna capable of operating in a frequency range of 1.97 GHz to 7.71 GHz has been proposed. ![]()
