A high-gain, three-antenna system suitable to be concealed inside wireless access points for multiple-input multiple-output (MIMO) applications in the WLAN 2.4/5.2/5.8 GHz bands is presented. The MIMO antenna system is composed of three dual-loop antennas occupying a moderate size of 10 × 20 × 40 mm3. Each dual-loop antenna further comprises a large outer loop and a small inner loop, both operating...
Circularly polarized (CP) antennas are attractive to wireless communications applications simply because less strict orientations are required for mobile stations (the end user) with respect to base stations. To achieve CP operation, many designs of patch antennas have been reported in the literature. However, for the designs utilizing dielectric substrates, single-feed, single-element patch antennas...
