By combining a folded plate and a double-layer metal structure with four apertures on its top floor, the proposed antenna has a dual-band characteristic and its gain reaches up to 11.9 dB with only 35 degrees (HPBW) of E-plane at 12.7 GHz and 12.1 dB with 39 degrees at 15.0 GHz. Compared to the conventional single-aperture flat antenna, the simulated and measured results show that the proposed antenna with resonant cavity achieves better impedance matching and low profile, meanwhile, the gain improved almost 5.2 dB at 12.7 GHz and 6 dB at 15.0 GHz, the HPBW of E-plane is reduced by 100 degrees and 108 degrees respectively.","claims":[{"public_id":"cl_14a658ca00e4aedff84f0b00d9b8cb30","status":"active","text":"A folded plate combined with a double-layer metal structure with four apertures yields a dual-band
