Design of Dual-band low profile rectangular microstrip patch antenna using FR4 substrate material for wireless applications

<p>This paper presents Dual-Band proximity coupled feed rectangular Microstrip patch antenna with slots on the radiating patch and Defected Ground Structure. Initially a simple proximity coupled feed rectangular Microstrip patch antenna resonating at 2.4 GHz is designed. Etching out a ‘Dumbbell’ shaped defect from the ground plane and ‘T’ shaped slot from the radiating patch of the proximity coupled feed rectangular Microstrip patch antenna, results in a Dual-Band operation, i.e., resonating at 2.4 GHz and 4.5 GHz; with 30.3 % and 18.8% reduction in the overall area of the patch and the ground plane of the reference antenna respectively. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 123.6 MHz and C-band at frequency of 4.5 GHz with bandwidth of 200 MHz, and a very good return loss of -22.1818 dB and -19.0839 dB at resonant frequency of 2.4 GHz and 4.5 GHz respectively is obtained. The proposed antenna is useful for different wireless applications in the S-band and C-band.</p>

Microstrip patch antenna is very popular and extensively used in GHz wireless communications. The demand of increased wireless communication applications, needs increase in bandwidth, gain, efficiency and isolation of microostrip patch antenna. Microstrip patch antenna is a low profile antenna but has narrow bandwidth, low gain, low efficiency and isolation. In this paper a microstrip patch antenna is designed with 1.6mm RT Duroid substrate material. The bandwidth, gain and isolation were found to be 60MHz, 7.5dB and -40dB with dual resonance. The bandwidth and isolation enhancement is achieved withsecond resonance suppression technique. The second resonance suppressed by using two slots. Simulations were conducted with different lengths of slots and at different positions and compared. A bandwidth of 270MHz, gain of 7.9dB and an isolation of -46dB are obtained. Bandwidth increase of 450% and 115% isolation increase are achieved.

Rectangular Microstrip Patch Antenna

This study describes the design of dual rectangular microstrip patch antenna for Wi-Fi and WiMAX wireless communication applications. In this work, the technique of design array patch antennas was used in order to improve the physical antenna characteristics for Wi-Fi and WiMAX device. As a result, the proposed technique causes to increase the gain and directivity of the antenna. Using this method also leads to enhance measurement bandwidth of antenna and some other antenna parameters as mentioned in this research paper. A dual-band microstrip patch antenna is developed for WiMAX/Wi-Fi wireless applications that operate at a minimum frequency of 2.4 GHz and a maximum frequency band of 3.5 GHz with its dimensions is L= 88.27 mm, W= 171.4 mm and h= 1.67 mm. The achieved parameters of dual patch array antenna for 2.4 GHz and 3.5 GHz are (gain of 8.25 dB, directivity of 10.4 dBi, measurement bandwidth of 65.82 MHz and measurement return loss of -20.86 dB) and (gain of 7.56 dB, directivity of 8.76 dBi, measurement bandwidth of 98.96 MHz and measurement return loss of -21.38 dB) respectively.
