被時尚雜誌評選台中4大必訪的文創聚落，其中座落在台中美術館附近的「留白計畫blank plan」也名列其中。「留白計畫」由三位八年級生創辦人王奕翔、林黛蓉、周亭亭精心設計的沈浸式藝文體驗空間，在成立短短不到一年間，已經成為眾多IG網紅的打卡聖地。

創辦人之一周亭亭說，「40年老空間本身就是一場大型創作，團隊從無到有打造寬闊空間氛圍，保留天井讓陽光自由灑落，樓層裡的大面落地窗能眺望台中綠地。」踏進空間可見大面積磨石子地板、隨處可見鐵鏽痕跡、柱體上的紅磚、牆面灰泥、客用老木桌與不修飾結構本身的樑與柱，她接著說，「保留部分歲月的樣貌，回歸到材質上的表現，是留白計畫的一大設計核心。」

「留白計畫」是改造4層樓老公寓，團隊推出不同策展、體驗、講錯，傳承老派美學。白天有「茶想」，由「講茶學院」創辦人湯家鴻舉行實驗茶席；也有「啡語」，透過扭蛋機轉出自己當天的手沖咖啡豆，親手體驗手沖咖啡，沖一杯屬於自己當天味道的咖啡。在晚間，有時也在調酒師楊子逸設計下，以酒杯為畫布，以酒水、香料為彩筆，進行一場酒精的微醺創作。

「留白計畫」開始前，也籌備一年多，其創辦團隊認為，藝文空間在這個時代尤其重要，而台中這座城市正在蓬勃發展，旅遊人數也是相對較多的地方，近年美術館附近的巷弄，更是開創出許多有意思的獨立小店與餐廳，街區氛圍與「留白計畫」的精神相呼應。

The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

一樓的「留白茶想」，邀請茶學專家、講茶學院創辦人湯家鴻進駐分享茶文化，運用茶農第四代、資工系背景的實驗精神投入泡茶流程，長年致力於台灣茶專業知識教授與國際推廣，將於現場帶來茶碗沖泡的茶道體驗，從茶歷史、時代器物特色到茶道精神，進行一場深度探索台灣茶文化的完整感受。此外，同步邀請插畫家吳睿哲Ray以「溫室」為題設展，運用剪紙技術，捕捉植物與生命模樣，演繹出細膩而純粹的線條。

二樓日間為「留白啡語」，夜晚則搖身一變成了「留白酒喃」。其中最重要的點睛之筆，借勢咖啡，該店與台灣咖啡品牌「井井」合作，並邀請熟捻無框架日式手沖流派「松屋流派」，現場滴濾泡出三種風味的咖啡。周亭亭分享，體驗時彷彿欣賞一場沉靜優雅的表演秀，松屋式為日本四大沖煮流派之ㄧ，流派精神強調不需高規格材質濾杯，僅以最簡單的鐵絲搭配濾紙或法蘭絨布，即可煮出風味乾淨且穩定的咖啡。

三樓選品空間中由「Blue Beach Denim 藍灘丹寧」主掌，品牌由一群熱愛牛仔褲、重視地球環境議題的台灣人 所組成，他們將牛仔視為第二層皮膚，如同 Nudie Jeans 的做法，講究留下材質隨時間變化的痕跡，對應老屋在歲月洪流留下的印記。同樓層展設佈滿植物與樹林的「森居」，創作者劉芷萱 Stephy 讓每一位參與者被大型植物創作圍繞，傳遞永續的生命循環。至於四樓的展區空間，也將不定時配合新舊技藝家，創造出屬於自己的展覽。
