COMPACT 3D MONOPOLE ANTENNA FOR DIFFERENT WIRELESS COMMUNICATION APPLICATIONS

A 3D compact printed monopole antenna for most of the wireless communication applications is proposed in this paper. The proposed antenna has dimensions 40 × 30 × 1.6 mm3; it is based on multi different length arms of E-shaped monopole with modified ground plane coupled with meander line. The performance of the 3D antenna is almost the same as a 2D antenna with reduction in size, and it could be fit in a wireless transceiver device. The size reduction about 25% compared to the 2D planar proposed antenna is realized on a printed circuit board to reduce the fabrication cost. The coupling between the antenna elements broadens the operating bandwidth, which includes most of the wireless commercial service bands, GSM1800/GSM1900/ UMTS/WCDMA2100 802.11b/g/LTE2600 (2690 MHz) as well as 802.11a/n (5150–5825 MHz). The antenna’s simulated and experimental results are in good agreement. It is fabricated on a low-cost FR4 substrate and measured to validate the simulation performances. Measured results display that the proposed antenna produces omnidirectional radiation pattern of −6 dB impedance bandwidth at multi operating bands and average gain of 3.5 dBi and 2 dBi for 2D and 3D, respectively over the operating band.
