Suapan apertur dengan rongga udara dalam pandu gelombang pasca dinding LTCC (Low Temperature Co-fired Ceramics) dengan pemalar dielektrik εr lebih daripada 5 dicadangkan untuk peningkatan lebar jalur dalam jalur gelombang milimeter. Rongga segi empat tepat diguna pakai kerana hanya satu corak topeng segi empat tepat boleh digunakan untuk setiap lapisan LTCC untuk mengurangkan bilangan parameter reka bentuk dan kos. Had fabrikasi seperti jarak antara tepi pos dan tepi apertur mengurangkan lebar jalur. Struktur suapan direka pada 61.25 GHz untuk julat εr dari 2.0 hingga 9.0. Dalam kes εr = 7.0, lebar jalur untuk pantulan di bawah -15 dB dengan rongga udara adalah 4.25 kali ganda daripada tanpa rongga udara dalam simulasi, dan 3.10 kali dalam pengukuran.

Abstract: The aperture feed with an air cavity in a LTCC (Low Temperature Co-fired Ceramics) post-wall waveguide with dielectric constant εr more than 5 is proposed for bandwidth enhancement in the millimeter wave band. A rectangular cavity is adopted because only one mask pattern of a rectangular can be used for each layer of LTCC for reducing the number of the design parameters and the cost. The fabrication limitation such as the spacing between the post edge and the aperture edge reduces the bandwidth. The feeding structures are designed at 61.25 GHz for a range of εr from 2.0 to 9.0. In the case of εr = 7.0, the bandwidth for reflection below -15 dB with the air cavity is 4.25 times that without the air cavity in simulation, and 3.10 times in measurement.
