Four claw-shaped parasitic branches are placed on the corners of the ground to widen the impedance bandwidth (IBW) and half-power beamwidth (HPBW) simultaneously. Several slots are etched on the radiation patch to obtain impedance matching. The proposed antenna is fabricated and measured. The experimental results show that the IBW for VSWR ≤ 2 is 72.5% from 1.02 to 2.18 GHz, and the 3 dB axial-ratio bandwidth is 54% from 1.15 to 2 GHz. The HPBW is beyond 100° overall CP bandwidth. Its dimensions are 70 mm × 70 mm × 12 mm, (0.35 × 0.35 × 0.06) λ ₀ ³ , where λ ₀ is the wavelength of the center frequency.23:T474,A simple structure E-plane decoupled millimeter wave (mmW) multiple-input multiple-output (MIMO) antenna based on current cancellation model is proposed in this communication. First, a coupling model of E-plane MIMO antenna is established by analyzing the coupling current. Then, a high-isolation two-element E-plane MIMO antenna loaded with decoupling branch Bar-L is designed by current cancellation method. Finally, a high-isolation four-element E-plane MIMO antenna is designed, fabricated, and measured to verify the applicability of the decoupling method in large arrays. The measured results show that the antenna achieves

dB in band of 25.5–26.5 GHz, and the measured isolation of adjacent ports in this band is greater than 35 dB, which effectively improves the isolation without deteriorating other performance. The proposed antenna with a simple structure is suitable for mmW MIMO systems requiring high isolation.24:T423,A novel dual-band circularly polarized (CP) planar endfire antenna with the front-to-back ratio (FBR) enhancement is proposed. First, a half-mode substrate integrated waveguide (HMSIW) cavity serving as a magnetic dipole (M-dipole) is devised for the dual-band vertical polarizations (VPs), and four slots are etched on the M-dipole to adjust the frequency ratio (FR) reasonably. Two independent electric dipoles (E-dipoles) are introduced for the dual-band horizontal polarizations (HPs). Then, the M-dipole and E-dipoles are connected by the parallel double-side compensate lines to adjust their amplitudes and phase differences, and thus, dual-band CP waves are radiated. A two-stage reflector is also loaded behind the M-dipole, which improves FBRs of the antenna in two bands. Finally, a 2.4/5 GHz prototype antenna is designed, fabricated, and measured to validate our design idea. A reasonable agreement between the simulated and measured results is obtained. Measured FBRs of the proposed antenna at 2.42 and 5.02 GHz are 15 and 14.2 dB, respectively.25:T485,An omnidirectional wireless local area network (WLAN) loop-slot antenna with common-mode current (CMC) suppression is proposed in this communication. First, based on the analysis of the equivalent model of odd-even
