Abstract
Beside low cost and easy to fabricate, there isn't enough bandwidth in any single antenna to accommodate all frequency ranges for basic rectangular antenna. The antenna with dual band frequency is proposed. This research presents various co-planar waveguide pentagonal microstrip patch antenna designs with multiple slots structure (MSS) techniques for dualband 3.5 GHz Worldwide Interoperability for Microwave Access (WiMAX) and 5.8 GHz Wireless Local Area Networks (WLAN) application. The simulation work is applied using CST Microwave Studio software while the fabricated antenna design in laboratory using FR4 substrate material (εr = 4.4, tan δ = 0.019). The work started with Antenna A with basic square patch antenna shapes. Then the Antenna B1, Antenna B2, Antenna B3, Antenna B4 with different shaped of patch including circular, triangular, square and pentagonal with coplanar waveguide (CPW) technique. Antenna C1 and Antenna C2 applied the first and second stage of multiple slot structure. The next stage of Antenna D1, Antenna D2 and Antenna D3 with CPW pentagonal island patch antenna with first, second and third stage of multiple slot structure. It then proceeds to the final stage of Antenna E1 and Antenna E2, CPW antenna with some modifications design mini pentagonal island and multiple slot’s structure. Besides that, the parametric study on a dual band CPW Pentagonal patch antenna for WiMAX and WLAN applications with multiple slot structure is presented in this work. As a result of the antenna's designs, the performance of the return loss, gain, and radiation pattern was impacted by the first and second multiple slot’s structure. For the last proposed design of Antenna E2, it shows that, the antenna is operate at two different point at 3.5 GHz and 5.9 GHz with return losses of – 25.662 dB and – 28.815 dB, respectively. For both resonant frequency points, it shows the bandwidth performance of 1.58 GHz (from 2.57 GHz to 4.15 GHz) and 2.4 GHz (from 5.13 GHz to 7.53 GHz). For antenna gain, it shows a 2.24 dB and 4.47 dB for each resonant frequency, respectively.
