Abstract
This paper presents an E-shaped flat dipole on an U-shaped cross-sectional ground plane. Dipole contributes from copper on the surface of FR4 to form the E-shaped. It is fed by a 50 Ohms coaxial cable. The frequency ranges is 1.5 - 2.8 GHz with return loss <;-15 dB. The antenna provides an average gain of 7.0 dBi and HPBW of 96 degree in the horizon plan and 62 degree in the vertical plan. The front-to-back ratio is greater than 18 dB on the U-shaped ground plane width of 160 mm, length of 110 mm and height of 40 mm. This antenna is suitable to use as a base station antenna with a linear polarization for DCS, PCS, UMTS and ISM bands. It is also the low-cost antenna.
