A Single Layer Dual-Polarization Printed Bow-Tie Slot Broadband Antenna with C-Band Stop
Authors: , , ,
Abstract: In this paper, a single layer dual-polarization printed bow-tie slot broadband antenna with C-band stop is presented. The proposed antenna consists of two pairs of mirror-symmetric and mutually perpendicular bow-tie slots with two coplanar waveguide (CPW)-fed. The proposed antenna has a very simple structure, and the measurement results show that the antenna performance can achieve a wide impedance bandwidth of 79.1% for | S11 | and | S22 | ≦ -10dB from 1.3 ~ 3 GHz and 62.3% from 5.25 ~ 10 GHz, which has been implemented to the operating band for GPS (1575MHz), WLAN band (2.4GHz and 5.8GHz), 6 GHz unlicensed spectrum (5.925 ~ 7.125 GHz), UWB band (3.1 ~ 10.6 GHz), LTE Upper band (LTE, 1710 ~ 2690 MHz) applications. The measured in-band isolation performance between the two ports | S21 | ≦ -15.5dB from 1.4 ~ 3 GHz, and | S21 | ≦ -21dB from 5 ~ 10 GHz is significantly achieved, and the radiation pattern, peak gain, and efficiency of the proposed antenna are measured as well. In the end, the simulated and measured radiation patterns are compared.
