Design and comprehensive testing a 2.4 GHz antenna for WiFi access point

[...]these frequency influence the antenna dimensions which reached 190x15 mm [5]. [...]the antenna apply directly to the AP TP-LINK WA 701 ND and conducting the connection test with various distances inside the building with several room; in this case at G building in the campus of Politeknik Negeri Padang. According to the antenna return loss in Figure 1 (c) the AP TP LINK WA-701 ND has the resonance frequency on 2.43 GHz. [...]the antenna is simulated using all of the optimum dimension and Figures 3 (g) and (h) shows the omnidirectional radiation pattern for 2D and 3D plots respectively which is good agreement to the premilinary result of the AP TP LINK WA-701 ND antenna radiation pattern measurement. 3.RESULT AND DISCUSSION The prototype of optimal dimension of the AP antenna is fabricated onFR4 material with 4.4 dielectric constant as depicted in Figure 4 (a).
