This paper presents a linear 1 × 2 “Ha ( )”–slot patch array microstrip antenna. The proposed design of an array microstrip antenna is intended for Wireless Local Area Network (WLAN) 2.4 GHz devices. From the previous research concerning the single patch “Ha ( )”–slot microstrip antenna, the gain that can be achieved is 5.77 dBi in simulation. This value is considered too small for an antenna to accommodate WLAN devices if compare to a Hertzian antenna. To enhance the gain of microstrip antenna, some methods can be considered using linear 1 × 2 patch array and T-Junction power divider circuit to have matching antenna impedance. The distances between two patches are one of the important steps to be considered in designing the patch array microstrip antenna. Thus, the minimum distance between the patch elements are calculated should be greater than λ/2 of the resonance frequency antenna. If the distance less than λ/2 electromagnetically coupled will occur, vice versa when it is to widen the dimension of the antenna will less efficient. Epoxy substrate Flame Resistant 4 (FR4) with dielectric constant 4.3 is used as the platform designed for the array antenna and it is analyzed using simulation software Computational Simulation Technology (CST) studio suite by which return loss, Voltage Standing Wave Ratio (VSWR), and gain are calculated. The simulation result showed that the designed antenna achieve return loss (S11) -25.363 dB with VSWR 1.1 at the frequency 2.4 GHz, and the gain obtained from simulation is 8.96 dBi, which is greater than 64.4 % if compared to the previous one. The proposed antenna design shows that increasing the number of patches in the array can technically improve the gain of a microstrip antenna, which can cover a wider area if applied to WLAN devices

“…Previous research has been conducted to analyze the effect of using different feeding technique on microstrip antenna, in which the result showed that the cut feed has better parameter performance compared to coaxial and microstrip line feeding technique [4]. From the previous research for cut feed or microstrip line feed with notch, the bandwidth only up to 60 MHz [5]. Furthermore, since bandwidth is one of the essential parameters for WLAN 2.4 GHz which should cover in the range of 100 MHz [6], better feeding technique should be utilized.…”

In this paper, single and dual element triangle patch microstrip antenna for WLAN 2.4 GHz is designed, analyzed and fabricated. Both proposed design utilized proximity feeding techniques. Afterwards the design is simulated on HFFS and optimized, which finally the dimension of both design for frequency 2.4 GHz is obtained. The best simulation result for both single and dual element triangle patch microstrip antenna is used as reference for fabrication on FR4 substrate with dielectric constant (□r) = 4.4 and thickness (h) 1.6 mm. The measurement result showed that the single element can achieve return loss (S11) -51.913 dB and VSWR 1.005 9 at 2.417 GHz, and then for dual element the result for return loss (S1) is -48.213 8 for VSWR 1.007 8 at 2.463 GHz. Compared to coaxial feeding technique, the proximity feeding has better parameter performance.

In this paper, the wideband planar sleeve antenna with two sleeves on the upper side and two sleeves on the bottom side are analyzed numerically. In the previous study, the wideband planar sleeve antenna is used at frequency 3.5 GHz. The purpose of this research is addressed to analyze the wideband planar sleeve antenna in the range frequency of 400-4000 MHz by using WIPL-D EM Simulator by adjusting the antenna parameter. The antenna upper sleeve, lower sleeve, the length of the antenna and the gap between the lower and upper sleeves are adjusted. The result shows that the wideband planar sleeve antenna is achieved. When the length of the upper sleeve is increased, the antenna will work at lower frequency but the return loss slightly reduced, the same effect occurred by increasing the lower sleeve size, but it doesn’t affect at the lower frequency. When the antenna length is increased, the return loss of the antenna is reduced. Furthermore, the distance between the lower and upper sleeve affects the return loss characteristic. This is indicated that by adjusting the length of the antenna parameter, the antenna is applicable for many systems, such as television system and the ISM system.
