Dual band modified square microstrip patch antenna with wideband is achieved by corner cut and inserting slits inside the edges of the radiating patch having slot loaded finite ground plane. It is observed that two operating frequencies at 3.21 and 4.03 GHz can be obtained. The obtained impedance bandwidths for 10 dB return loss for these operating frequencies are 15.58 % (500 MHz) and 27.8 % (1120 MHz) respectively. Compactness and dual band operation with wide bandwidth of this antenna is widely applicable for the wireless communication systems. KEYWORDS: Dual Band, Finite Ground, Impedance Loci, Return Loss, Wideband I. INTRODUCTION Conventional microstrip antennas in general have a conducting patch printed on a grounded microwave substrate and have the attractive features of low profile, planner configuration, low costs, lightweight, easy fabrication and capability to integrate with microwave integrated circuits. However, microstrip antennas inherently have a narrow bandwidth, and bandwidth enhancement is usually demanded for practical applications. Size reduction and bandwidth enhancement are becoming major design considerations for practical applications of microstrip antennas. For this reason, studies to achieve compact and broadband operations of microstrip antennas have greatly increased [1-10]. Microstrip patch antennas are widely implemented in many commercial applications of wireless communication. As the demand for increased electronic mobility grows the need for small handsets are most likely increased. Microstrip patch antennas are manufactured using printed circuit technology, so that mass production can be achieved at a low cost. In multichannel applications, a small instantaneous bandwidth is required over a large frequency range. Accordingly, tunable antennas provide an alternative to a broadband antenna in which an antenna with a small bandwidth is tuned over a large frequency range. In some applications, the system must work within two frequency bands that are far apart.

International Journal of Electronics and Communication Engineering & Technology (IJECET), ISSN 0976 – 6464(Print), ISSN 0976 – 6472(Online), Special Issue (November, 2013), © IAEME band antenna with wideband is used. If the antenna operates at two spot frequencies, then it is known as a dual band antenna. The electromagnetic simulation of the proposed antenna has been carried out using IE3D software of Zeland Software. Return loss, Smith chart, directivity etc. are being evaluated using IE3D software. II. ANTENNA DESIGN AND RESULTS In this patch antenna design, dual band modified square microstrip patch antenna with wideband is achieved by corner cut and inserting slits inside the edges of the radiating patch having slot loaded finite ground plane. The 50-ohm coaxial cable with SMA connector is used for feeding the microstrip patch antenna. Fig. 1 shows the front view of modified square microstrip patch antenna with slot loaded finite ground plane. It is observed that two operating frequencies at 3.21 and 4.03 GHz can be obtained, within the frequency range 2.5 GHz to 5 GHz with step frequency = 0.01 GHz, In this modified square patch antenna design, length of patch L = 30 mm, width of patch W = 30 mm with slot loaded and corner cut finite ground plane of the dimension L = 45 mm and W = 45 mm and square slot of dimensions 10 mm × 10 mm at the centre position, feed point locations at the patch is (11.825, -12.375). Fig. 2 shows the back view of modified square microstrip patch antenna with slot loaded and corner cut finite ground plane. Fig. 3 shows the variation of return loss with frequency for antenna design; the impedance bandwidth is taken from the 10-dB return loss. Fig. 4 and Fig. 5 show the radiation pattern for antenna design at lower (3.21 GHz) and higher resonance frequency (4.03 GHz) respectively. Fig. 6 shows the variation of efficiency with frequency for antenna design. Fig. 7 shows the Impedance loci (Smith chart) for antenna design. At lower and higher operating frequencies, the simulated input impedance of antenna is in good agreement with the 50 ohms impedance. Here due to modified square microstrip patch antenna with corner cut and inserting slits inside the edges of the radiating patch having slot loaded finite ground plane, the obtained impedance bandwidth for 10 dB return loss for these operating frequencies are 15.58 % (500 MHz) and 27.8 % (1120 MHz) respectively. The other radiation characteristics of the proposed antenna design for these operating frequencies are also coming out to be satisfactory.
