- Abstract
A dual band antenna based on the square planar dipole structure with interdigital capacitors is proposed. With this technique, the harmonic frequency band can be controlled as desired. The dipole element consists of two square copper plates with overall size of 21.6x13.8 cm2. The bandwidths of the proposed antenna are 170 MHz (1.71-1.88 GHz) and 200 MHz (5.15-5.35 GHz). The antenna gain of each band is obtained to be 10 dB and 8 dB, respectively. To increase the antenna gain, the array antenna composing of the two designed dipoles is studied. The size of array antenna is 21.6 cmx24.4 cm. The improved gains of 13.1 dB for the first band and 10.1 dB for the second band are obtained. The array antenna with four dipoles is also investigated. The high gains of 16.8 dB for the first band and 12.6 dB for the second band are obtained. The proposed array antennas have higher gains compared with the conventional array antennas with the same element numbers. Therefore, the proposed antennas can be suitably used for LTE and WLAN base stations.
